Articles About motor control
Articles are sorted by RELEVANCE. Sort by Date.
Over the many years, there have been many technical papers and articles about which motor is the best. The short and sweet answer is - let's talk about the application. More recently a number of papers and articles have appeared that compared each motor's advantages and disadvantages in generic or specific terms. Many times, the methods used to drive and control these motors are not completely described due to the many control schemes available for use. A few articles focus on just the open loop step motor and the closed loop servo motor advantages and disadvantages in a laundry list format. This article is attempting to "drill down" into the reasons why and to describe how it is done.

The secondhand on the Doomsday dial ominously spins around the face, slowly but ever so surely inching the motor industry towards its inevitable terminus:
News from Around the Industry
Over the past few decades, energy efficiency in motors has become an ever-increasing concern for OEMs and manufacturers alike. With multiple energy bills mandating higher efficiency across ever-broader spectrums of motors, including the most recent Small Motor Rule by the Department of Energy, efficiency has become an essential consideration when choosing a new motor.
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.
This issue we take a long, hard look at motor efficiency, and you should, too. After all, electric motors used in industrial settings are the single largest consumer of electricity in the United States. Upgrading your electric motors is not only good for the environment, but itâ™s also good for your bottom line. Sure, saving electricity lessens the burden on our countryâ™s energy infrastructure. But it also saves you money in the long run.
Th e total U.S. electric motor base exceeds 100 million motors and consumes more than 50% of all electricity generated in the country. Small motorsâ”fractional horsepower to 20-hpâ”comprise 99% of the motor population but consume only 25% of all generated electricity (Refs. 1,3,10,14).

If youâ™re an electrical engineer you know how an electric motor works; if you arenâ™t, it can be extremely confusing. Therefore, hereâ™s the simplified explanation (or the âœhow an electric motor works for dummiesâ version) of how a four-pole, three-phase AC induction motor works in a car.
When the need arises for linear motion or positioning, there are many choices. One can use an Acme screw, ball screw, rack & pinion, or belts. The cost of a linear motor solution is generally greater than a mechanical linear product, but when one needs highly accurate, repeatable, high-speed motion, then the answer may be a linear motor.
Beginning with this initial installment , and with the gracious permission of ABB/Baldor Electric, we are pleased to announce the beginning of a new series -- Baldor Basics: Motors. This is a collection of basicsdriven, motor-intensive articles authored by former Baldor engineer Edward Cowern, PE, a respected name by many in the electric motor industry. During his tenure at Baldor, Cowern - now enjoying his retirement - was tasked with producing a number of motor- and basics-related tutorials, primarily in response to a steady flow of customer questions regarding motors. Today's customers continue to ask questions and seek answers to address their various motor-related issues. As with Cowern's original introduction to the series, we hope you find these articles useful and would appreciate any comments or thoughts you might have for future improvements, corrections or topics.

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.
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.

Increasing pressure on many fronts is compelling mine operators to thoroughly examine every phase of their operations. Fluctuating demand that whipsaws mineral prices, government-imposed environmental regulations and rising operating costs related to maintenance downtime all pose serious challenges for the mining sector. Add pressure from customers and stakeholders for more sustainable operations as well as union demands for higher wages, and you have a scenario that requires mine operators to exercise every possible option to achieve more efficient operations.
One of the key challenges in the mining industry today is maintaining throughput in the face of ore grade quality that has declined by 40 percent in the last decade.
How would you compare the efficiency and capabilities of hybrid stepper motor actuators vs. can stack stepper motor actuators?
There are three major types of reluctance motors: all three reluctance motors are non-permanent magnet, brushless motors. They are synchronous motors with a non-linear relationship between torque and current. The variable-reluctance step and switched-reluctance motors utilize the principle of magnetic attraction by inducing magnet poles within the soft-iron rotor, and by energizing a set of coils wound around stator teeth resident in the laminated stator. These two reluctance motors must be sequentially excited to achieve continuous, steady-state rotation. The design of all reluctance motors requires finite element analysis (FEA) software.
When I woke up this morning, my house was a comfortable 68Â°F, despite the fact that overnight temperatures in the Chicago area were close to freezing. I donâ™t often think about the blower motor that helps circulate the warm air from my furnace throughout my house, but today I was grateful for it...

The Formula Renault 3.5 is seen as a crucial stepping stone on the way into the premier class, the Formula 1. Ambitious racers do not just bring their talents - they also have highly efficient motors on board to control the throttle of their 530-hp V8 engines.
Step motors come in many sizes and shapes. But they all share one item in common - each step motor type moves in discrete-degree steps. They react to a series of voltage pulses supplied by their basic controller, known as an "indexer." The step motor was the first to accept digital pulses, then move or rotate a prescribed amount without any feedback device. All step motors are position devices without the need to use any feedback devices. They operate primarily in an open-loop control scheme.
This product focus highlights the latest technology in electric motors.

A brief overview of the induction motor, including the basics of construction, performance and variable speed drives.
Recently I had a disturbing conversation with a colleague here at the office. During the conversation, it became clear to me that my co-worker -- a really intelligent guy whom I respect a lot -- had no idea how even the most simple electric motor works.
There are more brushless PM motors being made every day. These brushless PM motors are smaller in size -- i.e., less than 50 watts in power output found in hard-disk drives, CD and DVD players and many portable medical devices. Servo systems with brushless PM motors ranging from 50 watts to 50 kilowatts are now challenging the larger electric motor applications. A few manufacturers have pushed brushless PM motors above 200 kW.
University lab's motor eliminates pricey rare-earth magnets.
Electric motor-driven systems are the single largest enduser of electricity, accounting for over 40% of global consumption according to the International Energy Agency.
The use of motor current signature analysis (MCSA) for motor fault detection â” such as a broken rotor bar â” is now well established. However, detection of mechanical faults related to the driven system remains a more challenging task. Recently there has been a growing interest for detection of gear faults by MCSA. Advantages and drawbacks of these MCSA-type techniques are presented and discussed on a few industrial cases.

The motors might be small, but the big-brain technology driving these electrical wonders was on full display at the 2014 Small Motor & Motion Association Fall Technical Conference, convened November 4-6 in St. Louis, MO. SMMA, the manufacturing trade association (120 members strong) that tends to the best interests of the electric motor and motion control industries â” including manufacturers, suppliers, users, consultants and universities â” played gracious host to a wide array of presenters from an equally diverse range of sources â” from academia to the federal government. Like gears, motors are most everywhere, as evidenced by SMMAâ™s membership (consumer-, public interest-, national defense- and commercial-oriented) demographic which includes: appliance; transportation; medical equipment; office automation and computers; aerospace; and industrial automation. The associationâ™s mission: To âœserve as the principal voice of the electric motors and drives industryâ and to provide a forum to âœdevelop, collect and disseminate technical and management knowledge.â
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.

News from the industry about new products.
According to the Department of Energy (DOE), more than half of all electrical energy consumed in the U.S. is used by electric motors. To address this, several years ago, the DOE conducted a technical study as to what could be done to raise the efficiency levels of âœsmallâ motors. After years of study and litigation, the Small Motor Rule (SMR) was passed that covers two-digit NEMA frame single- and three-phase ¼ through 3 horsepower motors in open enclosures.
