YJ50

YJ50 motor is a new asynchronous generator which is developed for the equipment of large wind power generation by Yongji Electric Machine Factory, CNR. It can output 3 phase alternating current of 600kW or 125kW to the electric power circuit.
This generator has features of originality in structure, lower consumption and higher efficiency. Still it has the feature of security. Its performance reaches the international level.
New technology is applied as follows:
 Perfect design for the working condition of the asynchronous generator and circulation-free dual-winding.
 Stator coil adopted formed winding.
 Class H insulation structure with highly reliable performance.
 The technology of squirrel-cage rotor and special welding for conductor bar.
 Special choice of material and design to guarantee the overall vibration strength.
 Twin fans self-cooling inner circulation system.
 Sensor used to show timely the temperature of windings and bearings.
