When selecting a stepper motor for your application, there are several
factors that need to be taken into consideration:
n How will the motor be coupled to the load?
n How much torque is required to move the load?
n How fast does the load need to move or accelerate?
n What degree of accuracy is required when positioning the load?
While determining the answers to these and other questions is beyond
the scope of this document, they are details that you must know in order
to select a motor that is appropriate for your application. These details
will affect everything from the power supply voltage to the type and wir-
ing conguration of your stepper motor. The current and microstepping
settings of your IM483 drive will also be affected.

The stepping motor, while classed as a DC motor, is actually an AC mo-
tor that is operated by trains of pulses. Although it is called a “stepping
motor”, it is in reality a polyphase synchronous motor. This means it has
multiple phases wound in the stator and the rotor is dragged along in
synchronism with the rotating magnetic eld. The IM483 is designed to
work with the following types of stepping motors:
1) Permanent Magnet (PM)
2) Hybrid Stepping Motors
