Hannover Messe 2023 provides the latest technologies in robotics, automation, motion control, IIoT, fluid power, e-mobility, material handling and more. PTE's sweet spot, so to speak, are the vendors in the drive, fluid power, and motion control segments.
“Drive and fluid technology components are the central building blocks of machines, for power and motion, but also as a source of data for digital value-added services and crucial to the performance of customer products – this is what we will be showing at Hannover Messe,” said Hartmut Rauen, deputy executive director of VDMA
The following round-up examines some of the motor, gear and drive technology featured in Hannover this April.
High Efficiency low voltage NEMA motors SIE series (in the range from 1 up to 250 hp) are designed to withstand the most extreme, severe-duty applications (in compliance with the NEMA Premium requirements).
The NEMA Premium efficiency electric motors program refers to single-speed, polyphase, 1-250 hp, 2, 4, and 6 poles, NEMA Design A or B, continuous rated, squirrel cage induction motors.
These motors are designed for long life and reliable operation in most extreme industrial applications.
NEMA motors can operate in severe duty applications thanks to heavy-duty cast-iron construction. Special shaft sealing systems have been applied to increase the level of protection against contaminants.
They also offer NEMA brake motors. Apart from standard executions, they offer special JM/JP motors designated for driving of pumps.
The entire range of NEMA motors is certified according to CSA and UL standards.
Three-phase induction motors with output range from 0.06 kW to 2,500 kW with foreign ventilation (forced ventilation). Foreign ventilation is supplied independently of the main motor and built in the fan cover. Motors are adapted for speed control by frequency converter.
Cantoni Motor manufactures a wide range of traction motors (output power from 50 to 1,500 kW), and traction generators. Motors for various traction vehicles: trams (including low-deck trams), trolleybuses, subway, and locomotives.
Electromagnetic brakes are designed for braking rotating parts of machines and their task in areas such as emergency stopping, immobilizing machine actuators, acting as a positioning device, and minimizing run-on times of drives.
These brakes can be used in many application areas including industrial cranes, wind power plants, platforms, escalators, warehousing, cranes and more.
The Cantoni Group supports young and passionate engineers from Czestochowa University of Technology (Politechnika Czestochowska) in the implementation of innovative projects and appreciates their contribution to the development of advanced technology of the future.
For years the group has succeeded and has been awarded in many domestic and international competitions for their advanced projects including the Mars Rover.
Following the BG 66, BGE5510 and BG 95, the BG 75 brushless DC motor is now also available as a dPro version. With a continuous output power of up to 590 W, peak power of up to 1,700 W, and a peak torque of almost 5.8 Nm, the BG 75 dPro is more powerful than all other versions of the BG 75 series – with a supply voltage of just 24 or 48 VDC. This means more power in the same space, allowing machines to be built even more compact in the future. These characteristics makes the BG 75 dPro the perfect partner in the application fields of logistics, robotics, as well as machine and plant engineering. It can, for example, be used equally in the food, semiconductor, and electronics industries, or can operate as a drive for AGVs (Automated Guided Vehicles). Connection and programming is as easy as for all motors of the dPro family and is done either via CANopen or one of the Industrial Ethernet interfaces Profinet, EtherCAT or Ethernet/IP. The hybrid connector used for this reduces the cabling effort to a minimum. The motor can then be programmed, controlled, and monitored via the "Drive Assistant 5" commissioning and configuration tool and/or MotionCode.
With its DM66200H series, Faulhaber is upgrading performance for motors with an internal opening (aperture). As a direct drive, the new hollow shaft motor operates backlash-free and can be integrated into different applications with very limited effort. It achieves performance values in terms of both speed and torque. Its exceptionally wide aperture has a diameter as large as 40 mm. The drive is characterized by low weight and an extremely slim design. Thanks to minimal wear (bearing only), it is ideal for maintenance-free continuous operation.
The DM66200H hollow shaft motor offers a completely new drive solution for applications that require a very large aperture. The rotor runs around the opening and drives the mechanics surrounding this opening directly without the need for a transmission. Due to the design, it is extremely energy-efficient and requires neither a brake nor an encoder.
Despite the large aperture, the moving mass of the rotor remains small, making speeds of up to 2,000 rpm possible. The motor reaches a dynamic torque of up to 180 mNm and can move correspondingly large loads. With a high resolution of 1.8° in full-step mode, it can execute positioning tasks precisely in open loop operation.
Originally developed for precision optics applications, the DM66200H hollow shaft motor is suitable for many different application areas. It can be used wherever cables need to be guided through the aperture or in cases where gases, fluids or light signals are to pass through the opening. Apart from the field of optics - e.g., for microscope stages, apertures, zoom lenses, laser beam controls, etc. - it can be used for impellers and prostheses, in robotics as well as for many different control and positioning tasks. Other potential applications are turntables, antennas as well as air and gas extractors.

Linear axes and multi-axis systems for positioning tasks in automation. Linear guideways provide linear motion by re-circulating rolling elements between a profiled rail and a bearing block. The coefficient of friction on a linear guideway is only 1/50 compared to a traditional slide and they can take loads in all directions. With these features, a linear guideway can achieve high precision and greatly enhanced moving accuracy. Hiwin Corporation offers multiple linear guideway series, each featuring different options for sizes, loading capabilities, accuracies, and more.
The company’s strain wave gearing system has three basic components: a wave generator, a flex spline, and a circular spline. The elliptical shape of the wave generator, rotating against the thin, tooth lined flex spline, drives or is driven by the rigid circular spline which has more teeth than the flex spline. The result is a gear system that will reduce speed and increase torque. The unique properties of the strain wave gearing system allows it to achieve much higher gear ratios than other gear reduction solutions in a more compact space.

Following this development work Lafert has introduced a second generation of PM Synchronous Motors, named HPF, achieving IE4 Super Premium Efficiency level, with more stable and reduced production costs without applying rare earth magnets.
NKE manufactures bearings with ceramic rolling elements. Technologies are advancing rapidly and bearings must meet more sophisticated and varied requirements under increasingly demanding operating conditions.
In response to these special needs, NKE Austria and FERSA have committed to the development and manufacturing of hybrid bearings. Hybrid bearings can be used in new applications where conventional steel bearings have not been beneficial. For example, bearings with ceramic rolling elements are especially designed for applications where high-grade electrical insulation is necessary and/or high speeds occur.
Furthermore, NKE premium hybrid bearings possess excellent performance characteristics, like extended service life and reduced friction.
NKE spherical roller bearings are used to support high radial loads and compensate for misalignment of the bearing positions and/or increased shaft bending. This type of bearing is suited for applications with high loads and difficult operating conditions. NKE spherical roller bearings were designed to withstand such conditions in demanding operational environments. In order to achieve maximum strength and longevity high quality bearing steel is used. An optimized inner design with an increased number of rollers allows for higher load capacities of our products. The inner design is optimized for challenging operating conditions, reduces wear and heat and therefore the usage of lubricants. This results in less downtime and reduced effort and finally to a reduction of costs.
NKE provides bearings with oxide ceramic insulating layers on the bearing ring. Applied with plasma technology, the insulation has a guaranteed breakdown resistance of at least 1,000 V AC or DC.
Rollon offers the TH Series where the linear axis is fitted with a preloaded ball screw drive and ball guides with a ball chain. Due to its design features, it is especially well suited for applications requiring high performance and precision. The applications for the TH Series include laser applications, dosing robots and various handling tasks. This linear axis is characterized by high intrinsic rigidity and load bearing and offers additional flexibility with one or two carriages.
Compact Rail is the product family of roller sliders with guide rails made of cold-drawn roller bearing carbon steel. The raceways are located on the inside of a C-profile, thus protecting them from soiling. Fixed bearing rail, compensating bearing rail and compensation rail enable combinations for all applications in which deviations in parallelism must be compensated in one or two planes. Easyslide is the product family of compact linear ball bearings for high load ratings with long service life. They are equipped with one or several sliders per rail. If several sliders are used, they can each run, independently of one another, in their own ball cage or synchronized in a common ball cage. Different slider lengths and strokes can be selected. All Easyslide guides are particularly easy to mount. Easyslidel linear ball bearings are used in sliding doors on vehicles or machines and the like. The system made up of rail, slider and ball cage is particularly easy to mount, and is economical and reliable.
The low-wear, flexible gear couplings from R+W are used in a wide variety of industries. Particularly in heavy-duty operation – such as on the high torque shafts of mixers, rolling mills, crushers, test stands and conveyors – gear couplings transmit torques from 1,900 to 2,080,000 Nm with high torsional rigidity and low backlash. To ensure optimal performance, R+W manufactures both the coupling hubs and the flange sleeves with precise crowned gearing, made from high-strength steel.
Durable, reliable, and flexible: these characteristics make industrial couplings ideal for all applications that require maximum safety and performance in the face of constant and extreme loads. Engineers and operators across a wide range of industrial sectors are aware that machine component failures and downtime drive up cost and, in the worst cases, can lead to accidents – making proper industrial coupling selection critical.
The main advantages of elastomer couplings include vibration damping, easy installation, zero backlash transmission, and electrical isolation. Whether for machine tools, packaging machines, automation systems, printing machines or general mechanical engineering - the uses for elastomer couplings are as diverse as their requirements.
Elastomer couplings are part of a wider group, known as jaw couplings, the key component of which is an elastomer segment inserted between two hub halves. This elastomer insert is the heart of the elastomer coupling. It transmits torques from 0.5 to 25,000 Nm without backlash, and compensates for axial, lateral and angular shaft misalignment. When properly selected for size and hardness, the elastomer insert optimizes the entire drive train and exhibits important characteristics, such as vibration damping, torsional stiffness, and thermal stability.
The Neugart WPLHE combines all the advantages of the successful PLHE, as a right-angle variant.
Specifically, the WPLHE features both the gearing of a proven economy gearbox and a high-performance output bearing with preloaded tapered roller bearings, which are otherwise commonly used in precision gearboxes (such as the PLN and the PSN). This means that the new right-angle gearbox tolerates high radial and axial forces of up to 8,000 N at the output. For example, pulley drives with high radial loads can also be implemented in right-angle designs.
Compared to the coaxial PLHE the motor is rotated by 90° in this case, the WPLHE offers the ideal solution in confined spaces, for example in packaging and other special machines. It is an economy right-angle gearbox offered with a pre-mounted pinion as an option. This makes it particularly suitable for space and cost-sensitive rack-and-pinion drives. There are 13 different pinions from which to choose: with choice of straight-cut or helical-cut teeth, from module 2 to 3, with numbers of teeth from 15 to 27.
Thanks to the output geometry with square output flange and long centering flange that has become established on the market, the WPLHE is easy to implement. Several different output shaft variants - smooth, keyed, splined or with pre-mounted pinion - mean that the right-angle gearbox can be used in a wide range of applications. It also offers IP65 protection, making it suitable for harsh, dusty, and dirty environments. Food-grade and low-temperature lubricants are also available for the lifetime lubrication commonly provided by Neugart.
Additionally, the company will feature its economic planetary gearbox line for a wide variety of drive solutions.
