ERMA Permanent magnet electric motors with auxiliary cage rotor for a fixed speed application. Engine with a variable speed drive (VSD) for a variable speed application(8HP 72V)
The permanent magnet motor designed and made to measure by
ERMA Motors are controlled and operated through a frequency
inverter, which guarantees constant torque over a wide speed
range, operating even at the lowest levels with superior efficiency.
Therefore, these machines can also be defined as motors with
permanent magnets.
