BMD - Permanent magnet high performance servo motor

Permanent Magnet AC servomotors

BMD - Permanent magnet high performance servo motor, Electric motors for wind turbines

They are manufactured using the “salient pole” technology. The dimensions of the motor are drastically reduced, with considerable advantages in terms of torque density, overall dimensions and dynamic performance.
Thanks to the high quality and performance of the Neodymium iron boron rare-earth magnets maximize performance in terms of very high accelerations and withstand high overloads without risk of demagnetization of the magnets.
