The rotor position measuring device ensures that the same commutation angle is always produced with spindles of the same construction type during the installation of the e+a synchronous rotor. This dispenses with the need for individual programming of the commutation angle at the frequency inverter. When a spindle is replaced the drive can be monitored at all times and is therefore protected from being damaged beyond repair.

The motor must be mechanically driven in order to carry out a measurement. The measured values are easily read out using the RS232 interface in conjunction with measurement report software.
