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, ...

NUM’s new TMX series direct drive motors have an extremely low cogging torque, making them suitable for applications that demand very smooth and accurate rotation, especially at low speeds. Typical ...

Permanent magnet direct current (dc) motors convert electrical energy into mechanical energy through the interaction of two magnetic fields. One field is produced by a permanent magnet assembly; 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.

The case of a pulsating-load testing machine shows how to ballpark qualities that are important for deploying electric motors. Crankshafts in running internal-combustion engines pulsate as well as ...

There is increasing demand from engineers and specifiers working on complex motion control applications for cutting edge motors, especially those requiring high-torque, precise positioning and ...

Stepper motors are often used for positioning since they are cost-effective, easy to drive, and can be used in open-loop systems—meaning that they don’t require position feedback like servo motors.
