3 Overview
3.1 In General
3.1 In General
The highly dynamic synchronous AC servo motors of ELAU’s SB
series are permanently excited synchronous machines designed
especially for highly dynamic positioning tasks.
The low moment of inertia compared with other AC servo motors in
combination with the high overload tolerance not only guarantees
excellent acceleration values, but also reduces energy consumption
and stray heat of the motor.
The torque is generated by the stator coil fed by a sinusoidal threephase
current system in combination with the magnetic field excited
by the rotor magnets.
The generation of the rotary current system depends on the rotor
position in the digital motor controller or the positioning motor
controller.
For that purpose, the rotor position is monitored by a resolver.
Thanks to that principle, the drives are extremely robust and work
without wearing down.
3.2 Features of the servo motors
The SB motors are characterised by the following features:
� High reliability of maintenance-free
� Maintenance-free operation
� Overload protection (by motor temperature monitoring)
� High performance data
� High dynamics
� High overload capacity
� Large torque area
� sinusoidal EMK
� High volt technique = low currents
� Low mass-moment of inertia
� Motor link and feedback system over connection box
� Simple and fast commissioning (by electronic vehicle identification
plate in the SinCos encoder)
