Starting up

Motor characteristics

The following stepper motor parameters are important.

•   Step Angle
•   Current per Phase
•   Resistance per Phase
•   Inductance per Phase
•   Lead Wires

The motor torque during operation depends on the speed and
has to be taken from the motor characteristic curve.

Typical values:

Step Angle

Current per
Phase

Resistance
per Phase

0.9°, 1.8°, 3.6°

up to 1.5A

up to 10R

Inductance
per Phase

Lead wires

up to 5mH

4 / 8
