YDT Series Pole-changing Multi-speed Three-phase Asynchronous Motor
Product overview
YDT series motors are converted into variable pole multi-speed three-phase asynchronous motors for fans and pumps. They are derived products of Y series motors. The design of this series of motors is novel, and the torque decreasing characteristic is quadratic according to the load of fans and pumps: the power of the motor is proportional to the third power of the rotating speed, and the torque is proportional to the square of the rotating speed. According to the matching requirements of the rotating speed, the corresponding power is reasonably matched, thus saving a lot of energy and measuring the ideal power of the fan load type. Widely used in metallurgy, mining, textile, printing and dyeing, chemical industry, light industry, construction and civil facilities and other departments. The installation size of YDT series motors is the same as that of Y series motors, and the protection level is P44. It has the advantages of high efficiency, energy saving, low noise, good insulation performance, reliable operation and convenient maintenance. YDT series motors comply with international IEC standards, and the main technical tenders have reached the advanced level of similar products at home and abroad. The company YDT series motor according to JB/T8681-1998 standard production.Category:
