YDT series change-pole multi-speed three-phase asynchronous motor for fans and pumps is an energy-saving product promoted by the state government. The series of motor design is novel. According to the theory that the fan and pump load has characteristics of quadratic decreasing torque, motor power is proportional to cubic speed, the square of torque is proportional to the square and speed, match the right power for speed requirements. thus it can save a lot of energy, it’s the ideal power of  fan load type. It is widely used in metallurgy. Mining, textile, printing and dyeing, chemical, light industry, construction and civil facilities and other fields. 

YDT series motor has the same outline and installation dimensions as YE2 series , the protection level is IP54 and IP55. There are two types of two speeds and three speeds, It has features of high efficiency, energy saving, low noise, low vibration, good insulation performance, reliable operation, easy maintenance and other advantages.
