1 Introduction
1.1 Motor family
The motors are 3-phase stepper motors with a very high power density.
They carry out precise step-by-step movements that are controlled by a
drive.
The 3-phase stepper motors are accurate, powerful and sturdy and ex-
cel with a high power density. Due to the high holding torque, a gearbox
is not required in most cases. Sine commutation allows for almost fully
resonance-free operation of the motor.
A drive system consists of the 3-phase stepper motor and the appropri-
ate drive. Maximum performance requires the motor and drive to be
adapted to each other.
Features The motors excel with the following features:
Positioning accuracy and speed accuracy
Very queit and almost resonance-free
Dynamics and high peak torque
High power density
Excellent dynamics
Broad torque range
Special winding for low phase currents
Motor connections via flying leads, terminal box or connector
Easy commissioning
Low maintenance
High overload capability
