Modification and application of earth permanent magnet motors in twisting machines of textile equipment

Recently, our company has transformed more than 1,000 permanent magnet motors of double twisting machines in a textile enterprise in Zhejiang. 7.5KW earth permanent magnet motors have replaced asynchronous motors. The active power saving rate has reached 11.5%. After the entire transformation of the enterprise is completed, every month It can save hundreds of thousands of kilowatt-hours of electricity, bringing direct economic benefits to customers. Moreover, because the earth permanent magnet motor does not require reactive power compensation, the motor current is reduced, and the diameter of the cable can be reduced, further reducing cable losses and also connecting It saves enterprises time in electricity bills, and because of the reduction in reactive power losses, the capacity of the transformer can also be reduced, and the cost of power distribution can be greatly reduced.
