Motor stray losses: loss of stray current to the motor is still in the research stage know, now some of the main ways to reduce the stray losses are: (1) the use of heat treatment and surface finishing lower rotor short circuit; (2) the surface of the rotor slot insulation treatment; (3) reduction through improved design harmonic stator windings; (4) to improve the design and fit with the rotor slot harmonics YE3 ultra-efficient motors reduce, increase fixed, the rotor slots, the rotor groove designed chute, using string pick sine winding, winding and short interspersed winding can greatly reduce the high harmonics; Using magnetic slot wedge clay or magnetic alternative to traditional insulation wedge, mud tank filled with a magnetic motor stator core ultra-efficient energy-notch YE3 motor, is an effective way to reduce the loss of additional stray. Zhengzhou Dresdner Cheung Motor Manufacturing Co., Ltd. mainly produce series of ultra-efficient energy-saving motors YE3 0.55-375KW (80-355); part YE2 series of high efficiency motors, FX, FW, JF02, F02 series of textile motors; JW miniature motors. While the production of ZD, YEZ series cone motors, as well as spline, pumps and other special specifications, models of the motor, Henan Province is the large-scale private motor manufacturing, most varieties of professional motor manufacturer. 2002 was "Zhengzhou Trade and Industry Guide" is designated as Zhengzhou City Electrical Industry invited contributors units. YE3 super energy-efficient motors, motor Dresdner Cheung (certified), Simao motor supplied by the Zhengzhou Dresdner Motor Manufacturing Co. Cheung. Zhengzhou Dresdner Cheung Motor Manufacturing Co. (www.deshengxiangmotor.com) (www.deshengxaingmotor.com) is Zhengzhou, asynchronous motor leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum to meet customer needs.
