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