DH07VSD-DH410VSD Oil Free Walter-Injected Screw Comporessor

Electric rotor

Permanent magnet rotor, with smaller loss and eciency increase by 5-10%

Small volume and light weight

1-2 frame-size smaller compared with same-power asynchronous motor

Low noise

Reasonable groove-pole matching, magnetic field design, wider operating frequency, and lower operation noise

Large starting torque

The starting torque and overload capacity of permanent magnet synchronous motor are one power level higher than that of asynchronous motor.

No-shock starting

Smooth soft start, with starting current not more than 2 times of the rated current

Large starting torque

The rotor does not need electrical excitation and can achieve high torque at low speed
