Since 1978, Applied Motion Products has specialized in offering two-phase, hybrid step motors in a variety of frame sizes. These motors are designed to work optimally with Applied Motion stepper drives, ensuring smooth motion and high performance in every application. Add an encoder to the rear shaft of an Applied Motion step motor, marry it to an Applied Motion drive equipped with encoder-feedback functionality, and dramatically improve system performance.

What is the accuracy of your stepper motors?
Our stepper motors have a step to step accuracy of +/- 5% of a full step, so for a typical 1.8° per step motor this is +/- 0.09°. Here is a typical plot of error versus position.
What’s the difference between detent torque and holding torque?
Detent torque refers to the small amount of resistance that can be felt when turning the motor shaft while the stepper drive is powered off or with the motor lead wires disconnected. The detent torque, which is sometimes called cogging torque, is the result of the magnetic interaction between the the rotor and stator. The holding torque is the amount of torque the motor shaft can produce while stationary with full rated current flowing in both phases of the 2-phase stepper motor’s windings Holding torque is one of the primary specifications for any stepper motor. Here is a typical chart showing holding torque and detent torque versus position.
My step motor stalled and is making a funny noise. Will it burn up?
As long as you are operating the motor at or below the rated current and it is properly mounted so that heat can dissipate, it will not be damaged by stalling.
