Compare products offered by stepper motor manufacturers

When choosing a stepper motor, the number of rotations (steps) per minute determines the precision of the motor. The type of winding scheme, the driver and the torque required are also important factors to compare. Check out a stepper motor forum online for tips on which models offer the best performance.

I recommend: Ledex-Johnson Electric is a certified manufacturer of all types of stepping motors (including rational and linear) with varying torques. Industries served include business machines, heating ventilation, air conditioning, industrial equipment and automation, leisure, fitness and medical equipment. M Squared Electronics is a stepper motor supplier of full step, half step or fractional stepping motors for industrial and commercial applications.  For a stepper motor forum, check out Eng-Tips.

Purchase a waterproof stepper motor or a submersible stepper motor

Waterproof stepper motors are used in applications where splashing or chemical spills might occur. Fully submersible stepper motors are used in water applications.

I recommend: Bearing Industrial and Supplies is a distributor of stepping motors, including waterproof stepping motors. Lin Engineering offers a submersible stepper motor from depths of 15 centimeter to 1 meter. Lin also offers a dust proof, water resistant stepper motor driver that's protected against damaging environmental elements.

Find a micro-stepper or miniature stepper motor for an electronic application

Some stepper motors are designed specifically for micro-stepping and have tighter machining tolerances on the teeth. Miniature step motors are used in telecommunications, hobby and quality modeling, as well as optical, video and audio applications.

I recommend: WZ Micro offers several low cost miniature step motors for computer drives. Oriental Motor USA offers five and two-phase micro-step packages with programmable drives and controllers.
