Specific measures energy efficient motors loss: energy efficiency measures electrical motor is a systematic project involving the entire life cycle of electrical motors from the motor design, manufacture motor selection, operation, adjustment, repair, scrap, the entire life cycle of the motor from its consideration of the effect of energy-saving measures, the main consideration in this respect at home and abroad to improve the efficiency of the motor from the following aspects. Saving motor design is the use of modern design tools optimized design technology, new materials technology, control technology, integrated technology, test technology, reducing the motor power loss and improve the efficiency of the motor, the design of efficient motors. Motor in converting electrical energy into mechanical energy, while part of the energy loss itself, typical AC motor loss can generally be divided into a fixed loss, variable loss and stray loss of three parts. Variable loss is included with the load changes, including the stator resistance loss (copper loss), loss of rotor resistance and brush resistance loss; fixed loss has nothing to do with the load, including core and mechanical losses. Iron loss but also by the hysteresis loss and eddy current losses are composed of a voltage proportional to the square, which is also inversely proportional to the frequency hysteresis loss; other stray losses are losses and other loss of mechanical efficiency motors, including the bearing friction loss and fan rotor and other losses due to windage loss rotating rotor winding resistance caused by: loss of main rotor and the rotor current and rotor resistance of the corresponding energy-saving methods are: (1) reducing the rotor current energy-saving motors, which can increase the voltage from and motor power factor of two considerations; (2) increase the cross-sectional area of ??the rotor slots; (3) reduce the resistance YE3 rotor windings, such as the use of thicker wire and low resistance material, which is more meaningful for small motors, because of the small General Motors cast aluminum rotor, the use of copper rotor motor total losses can be reduced by 10% to 15%, but there needed to manufacture copper rotor temperature is high and the technology is not yet universal, the cost is higher than the 15% to 20 cast aluminum rotor % export motor, motor Anyang, Allianz Dresdner Xiang Xiang is provided by Motor Manufacturing Co., Ltd., Zhengzhou.
