Forms:motor drive + permanent-magnet variable speed motor + permanent-magnet generator , you can use a Brushless DC motor or a permanent magnet synchronous motor as the variable speed motor.
Applications: wind turbine generation simulation, the water power generation simulation, frequency converters, DC-AC converter, university lab equipment.
Motors have multiple poles, stable operation; you can use DC power (battery) or AC power.
Generators can have multiple poles. High-frequency voltage can be gained even at a very low speed . Generators can be made six-phase output, for a particular purpose.
The structure is compact, no carbon brushes, no excitation winding, no spark.
The system can be equipped with encoder, brake, thermistor, and even controlling box, Rectifier , load box.
The rotor intensity is high, the motor can reach higher speed.
Running efficiently throughout the entire speed range, saving energy.
Small size, light weight, high energy density, fitness for a particular occasion.
Air cooling or water cooling, low temperature. Use high speed oil-containing bearings, maintenance free, higher reliability and longer life .
The whole system is fixed to the public chassis, easy to install, much stability, elegant in appearance.
