NOTES - All ECM machines can operate as a motor or generator.When operated as a motor best performance is obtained with high frequency sinusoidal drives.70μH per phase of external inductance is recommended when operated with conventional <40kHz drives.* Rotor and Stator Only - Housing design is an important consideration.
Volts: 8.40
