Most manufacturers of shaft-mounted speed reducers offer torque arms for their products. However, in some situations, a machine designer may be required to design his own.
This paper presents a joint project conducted by Ashwoods Electric Motors and Oerlikon Fairfield that uses planetary drives with an integrated electric motor. Current solutions used in production of off-highway vehicles rely upon large, heavy and inefficient brushed DC or induction motors, coupled to a planetary gearbox. This presents a number of challenges to the vehicle designers such as: limited vehicle range, limited space around the motor/drivetrain, and motor durability. The proposed integrated system utilizes an Oerlikon Fairfield Torque Hub, widely used in off-highway vehicles, and the Ashwoods first-to-market, interior permanent magnet motor. How these products are integrated, i.e. incorporating a brake solution, represents a market-changing product. Using interior permanent magnet (IPM) technology in the motor design means the motor can be up to 70% lighter, 70% smaller and 20% more efficient than traditional motors used in off-highway traction applications.

How to Ensure Reliable Performance, Increased Efficiency and Lowest Total Cost of Ownership.
It's no secret that conveyor systems are the primary market for gearmotors, and so it shouldn't be much of a surprise that gearmotor manufacturers are looking for ways to cater to that market's needs. From Brother's new VFDs to Siemens' Simotics S-1FG1, a lot of the new solutions in the industry have their own unique quirks, but all fall into a few common veins.

Gearmotor manufacturers find new ways to push the envelope. (With Sidebar on new alternative to planetary gearboxes)
Standing in a factory or a warehouse, you're bound to notice machinery, whether it's a conveyor system that winds across the floor or large fans that hang from the ceiling. You may even notice automated guided vehicles or autonomous mobile robots carrying parts, driving themselves from one section of the building to another. These machines are good candidates for using high-efficiency gearmotors, especially if they're expected to run for long stretches at a time. If they aren't using high-efficiency gearmotors, then they may be costing more money than they should.

The following article explains the commonly used paint components and methods within the gearmotor industry, with a focus on electrodeposition coating (E-Coat). These processes will be described in general, with a closer examination of the E-Coat applications steps. Some pros and cons of each method will be presented along with comparative test results showing the benefits of E-Coat.

Heavy industry. The phrase conjures images of mines and steel mills, of huge caverns underground, of cavern-like factories, of oldline companies operating heavy-duty machines for hightorque work. That's the image of heavy industry. Today, though, there's also another image. It's of an operator walking a steel mill's floor, looking at his smartphone or his tablet.
Energy efficiency is for more than just motors. Here are some mechatronics companies making sure you get more bang for your buck when it comes to your power bill.

Industrial mainstay adapts to remain relevant in a 4.0 world
The secondhand on the Doomsday dial ominously spins around the face, slowly but ever so surely inching the motor industry towards its inevitable terminus:
A wide variety of companies displayed mechanical power transmission and motion control technologies at Pack Expo, held in November in Chicago. The event, which is the largest packaging and processing trade show in North America, attracted more than 48,000 attendees, according to show owner and producer PMMI. The four-day event included 2,352 exhibiting companies, an increase of more than 19 percent from the previous show in 2012.
Novatorque energy efficient motors, Portescap smaller-size brushless DC motors, Pittman customized motors, Kollmorgen stainless steel motors, Crouzet expanded motor series, and a report from IHS on rare earth mineral supply.
Norkol Converting Corporation is one of the nationâ™s leading independently owned converters and distributors of commercial printing papers. The company has full production capabilities and state-of-the-art machinery for winding, trimming and sheeting. The company utilizes traditional slitter re-wind equipment that unwinds, slits and then re-winds paper to new dimensions. These conventional re-winders, while typically producing new widths of paper with clean cuts, work at an inefficient, slow pace.
The use of motor structures which can concentrate magnetic flux allows ferrite PM motors to achieve performance and power densities that approach those of PM motors using rare earth magnets, but without the cost penalties and supply source concerns of rare earth magnets.

Permanent-magnet, synchronous-torque motors offer significant advantages on high-energy-consuming and high-dynamic applications.
The issue might be a faulty treadmill at a local gym, the need to update orthopedic surgery equipment or simply a train stuck in neutral at the toy store. Whatever the case may be, viewing e-mails in the marketing department at Torque Transmission is like opening Christmas presents every morning.
The world of high horsepower drives often calls for mechanical design to be approached from different perspectives. As motors, gearboxes and machines increase in size, power density can become disproportionate from one driveline component to the next, emphasizing the need for more rugged, robust and compact equipment.

Few industries are experiencing change quite as fast as the packaging arena. Lighter-weight containers are being introduced to reduce costs and energy use, packaging is being redesigned to attract consumer attention and manufacturers are using fewer materials in an effort to address environmental concerns.
An exploration of direct drive motor trends and examples of design uses for direct drives as replacements for gear drives or belt drives.
The primary driver of an airport baggage handling queue conveyor must be able to operate under increasingly demanding operating conditions, including frequent starting and stopping. The selection of the primary driver of the queue conveyor is dependent on multiple criteria, including dimensional requirements and durability characteristics.
In the process of applying industrial drive products, we occasionally are misled into believing that we are applying horsepower. The real driving force is not horsepower - it is torque. This paper is developed to impart a deeper understanding of torque, its relationship to horsepower, and the types of loads we most frequently encounter.
In today's highly competitive world, the better someone understands the advantages and benefits of direct drive technology, then the more they will have an advantage in machine building, giving them an edge over their competition.
When talking about high-end machining or manufacturing applications that include direct-drive technology, one of the key advantages of utilizing this particular transmission method is its endurance. Because of the very nature of direct-drive motors they are able to operate at peak performance levels indefinitely â” without any kind of wear or aging â” as long as the motor isnâ™t pushed past its capacity. Unfortunately, because this isnâ™t a perfect world, unexpected things can happen which can cause the motor to overheat. Whether the heat source is due to a parameter being input incorrectly, or an unexpected external force causing more resistance than expected â” it is important to have certain forms of thermal protection in place. Since torque motors are built in such a way that they cannot be repaired and yet maintain their efficiency, it is vital to prevent any overheating â” thus precluding the need to purchase a new one.
