Stepper motors have the following benefits:

• Low cost

• Ruggedness

• Simplicity in construction

• High reliability

• No maintenance

• Wide acceptance

• No tweaking to stabilize

• No feedback components are needed

• They work in just about any environment

• Inherently more failsafe than servo motors.

There is virtually no conceivable failure within the stepper drive module that could cause the motor to run away. Stepper motors are simple to drive and control in an open-loop configuration. They only

require four

leads. They provide excellent torque at low speeds, up to 5 times

the

continuous torque of a brush motor of the same frame size or double the

torque of the equivalent brushless motor. This often eliminates the need

for a gearbox. A stepper-driven-system is inherently stiff, with known

limits to the dynamic position error.

Stepper Motor Disadvantages

Stepper motors have the following disadvantages:

• Res onance effects and relatively long settling

times

• Rough performance at low speed unless a
