Selecting a motor for a specific application can be a challenging task. Many factors must be considered, including the application’s required voltage, maximum current and diameter, speed, efficiency, ...

The optimal size for a clutch or brake is determined by three things: Required torque, thermal horsepower per engagement, and average required thermal horsepower. Here, we'll discuss the first, ...

The driver is a key factor in determining a motor’s stall performance. Temperature can affect the stall torque of brushless DC motors. Tolerances on the motor parameters can significantly impact the ...

When it’s time to specify a high-performance motor that offers both precise positioning and cost efficiency, stepper motors offer many advantages over DC motors thanks to their brushless technology.

Evaluating tribological properties such as friction coefficients, friction forces, and torques for arbitrary material pairs, with high precision is crucial for multiple areas of research and industry.

Selection of replacement motors is usually straightforward if the ratings are equivalent. Sometimes, however, a different type of motor is necessary or desirable. For success in these cases, it is ...

The U.S. motor industry has worked on a standardized basis for more than three-quarters of a century. The standardization agency — National Electrical Manufacturers Association (NEMA) — was ...
