EM-A PM motor series - Mitsubishi Electric

EM-A Series from Mitsubishi Electric include newly developed Permanent Magnet (PM) 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).

Features

The EM-A series from Mitsubishi Electric offers a high-performance, cost-effective, and efficient solution for the industrial sector, combining sensorless control and a salient pole core for fast and precise response. It is ideal for applications requiring strict motion control, such as robotics and advanced automation. Despite its high precision, this series has technological limitations in terms of positioning and synchronization that should be taken into account, thus not invalidating servo motor solutions. The EM-A line reaffirms Mitsubishi's commitment to technological innovation, enhancing efficiency, simplifying integration and maintenance, and promoting more competitive and sustainable industrial operations.
