Stepper Motor Advantages and Disadvantages

Stepper Motor Basics
"A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements. The shaft or spindle of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence. The motors rotation has several direct relationships to these applied input pulses. The sequence of the applied pulses is directly related to the direction of motor shafts rotation. The speed of the motor shafts rotation is directly related to the frequency of the input pulses and the length of rotation is directly related to the number of input pulses applied."

This is a topic about the Stepper Motor Basics, after read this artical, you will know basic informations about stepper motor.

Stepper Motor Advantages and Disadvantages


1. The rotation angle of the motor is proportional to the input pulse.

2. The motor has full torque at standstill (if the windings are energized)

3. Precise positioning and repeatability of movement since good stepper motors have an accuracy of 3 – 5% of a step and this error is non cumulative from one step to the next.

4. Excellent response to starting/stopping/reversing.

5. Very reliable since there are no contact brushes in the motor. Therefore the life of the motor is simply dependant on the life of the bearing.

6. The motors response to digital input pulses provides open-loop control, making the motor simpler and less costly to control.

7. It is possible to achieve very low speed synchronous rotation with a load that is directly coupled to the shaft.

8. A wide range of rotational speeds can be realized as the speed is proportional to the frequency of the input pulses.


1.    Resonances can occur if not properly controlled.

2.    Not easy to operate at extremely high speeds.

The motors that are included in a motor home may be different than a stepper motor but the general dynamics are the same. Those who are looking for a motor home for sale should be especially wary of the condition of the motor, though you can always go to an RV dump site to look for spare parts.
