MITSUBISHI ELECTRIC cambia in meglio
EM-A Series include newly developed permanent magnet motors using the patented salient-pole core. The rotor consists of the salient-pole core and surface-mounted permanent magnet, and therefore the motor inductance changes depending on the rotational position. This change in inductance is applied to the sensorless control. The combination of the newly developed salient-pole magnetic motor and Mitsubishi’s unique high-performance sensorless control technique realizes high precision speed control and positioning control without a sensor (encoder).
