Section Overview

This section covers the motor configurations for the IM483.

 Selecting a Motor.

 Motor Wiring.

 Connecting the Motor.

Selecting a Motor

When selecting a stepper motor for your application, there are several factors

that need to be taken into consideration:

 How will the motor be coupled to the load?

 How much torque is required to move the load?

 How fast does the load need to move or accelerate?

 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 wiring configuration

of your stepper motor. The current and microstepping settings of your IM483

drive will also be affected.

Types and Construction of Stepping Motors

The stepping motor, while classed as a DC motor, is actually an AC motor 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 field. The IM483 is designed to work with the following types of

stepping motors:

1) Permanent Magnet (PM)

2) Hybrid Stepping Motors
