Product overview
4.1
Function
The product is a permanently excited, electrodynamic, brushless servo motor. The
integrated absolute encoder serves to record the angular position and derives the
angular velocity signals and other status variables. These signals are evaluated
by a higher-order servo drive. The de-energised holding brake enables the motor
shaft to be held at a standstill.
