MAX-4/11/03/016/99/1/1/00 ELAU driver/motor/amplifier supply

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.

The SB motors are characterised by the following features:
1.High reliability of maintenance-free
2.Maintenance-free operation
3.Overload protection (by motor temperature monitoring)
4.High performance data
5.High dynamics
6.High overload capacity
7.Large torque area
8.sinusoidal EMK
9.High volt technique = low currents
10.Low mass-moment of inertia
11.Motor link and feedback system over connection box
12.Simple and fast commissioning (by electronic vehicle identification plate in the SinCos encoder)
