Permanent magnet sensorless motor.pdf
  Performance and Characteristic:
High efficiency and energy saving: high temperature rare earth permanent magnet material, special stator trough and the rotor structure, make the motor efficiency IE4
Small&light weight: The frame is smaller than same power asynchronous motor, more compact volume.
High reliability: current decrease, lower temperature, motor longer life
High performance: the moment of inertia of smaller, big start torque, wider operating frequency
Control is simple, reliable: adopts frequency conversion vector control method, high control precision  and reduce the fault segment
Strong commonality: same as the asynchronous motor structure, can directly replace the asynchronous motor.
