Product Profile:

When the AC asynchronous motor starts at rated voltage, the initial starting current is very large.It often exceeds the current of the rated circuit several times (usually 5~7 times).In order to reduce the starting current and not affect the power grid, the method of lowering the voltage is usually used to start the AC asynchronous motor.The product is designed according to the starting characteristics of the high voltage asynchronous motor, matching the motor power 220~1200kw.

Technical characteristics:

The coil is epoxy resin vacuum pouring coil.The epoxy glass grid cloth is strengthened inside and outside the coil, and the F epoxy pouring system is used in the vacuum state.The coil not only has good insulation performance, but also has high mechanical strength, and can withstand large current shock and cold and hot impact without cracking.The end face of the iron core is made of high quality silicon steel sheet end face glue, so that the iron core column and the iron yoke are firmly combined together, and the noise of the product operation is greatly reduced.The advanced vibration and noise reduction structural system includes:(strong clamping of the upper and lower clamps, set torque in strict accordance with the material, the elastic rubber pad is arranged between the clamping piece and a coil, sandwiched between the base and the elastic rubber pad.
