Rotor winding resistance loss: loss of main rotor and the rotor current and rotor resistance of the corresponding energy-saving methods are: (1) reducing the rotor current industrial energy-saving motors, which can be considered to increase the voltage and motor power from two factors; (2) increasing the cross-sectional area of ??the rotor slots; (3) reduce the resistance of the rotor windings, such as the use of thicker wire and low resistance material, which is more meaningful for small motors, because of the small electric motor is generally cast aluminum rotor energy-saving motors, if 1.5kw saving using copper rotor motors, motors total losses can be reduced by 10% to 15%, but copper rotor temperature is high and the technology required to manufacture energy-saving motors company is not yet universal, the cost is higher than the aluminum rotor 15% to 20% . Dresdner Cheung motors are widely used in construction, mining, food, hydraulic, medical, textile, printing, shearing, punching rolling, power drill, small machine tools, fans, and other mechanical equipment, facilities, and can be designed according to user requirements manufacturing various types of special specifications, models of the motor. With a powerful, energy saving, reliable, overload operation features, is ideal for all types of machinery and equipment for power. Selling products, and supporting exports to Nepal, Italy, Pakistan, Russia and Southeast Asia and other countries.
