DES-YJ50 motor is a new asynchronous generator used for large wind power generation. It can output 3 phase alternating current of 600kW or 125kW to the electric power circuit.
The generator features security, originality in structure, lower consumption, higher efficiency and world level performance. New technology is applied as follows:
1 Perfect design for the working condition of the asynchronous generator and circulation-free dual-winding.
2 Stator coil adopted formed winding.
3 Class H insulation structure with highly reliable performance.
4 The technology of squirrel-cage rotor and special welding for conductor bar.
5 Special choice of material and design to guarantee the overall vibration strength.
6 Twin fans self-cooling inner circulation system.
7 Sensor used to show timely the temperature of windings and bearings.
