3-phase stepper motor 9

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
