The efficiency index of this series of products reaches the level 1 standard of GB30254-2013 "High-voltage Three-phase squrriel Cage Asynchronous Motor Functional Efficiency Limiting Value and Energy Efficiency Grade", achieve international advance level.
===
The installation dimensions of this series of products are the same as those of the TYKK basic series. The basic series is TYPKK air-air cooled, ingress protection class IP55, insulation class F, S1 working duty. Other protection classes and cooling methods can be supplied according to customer needs.
The series is rated at 10kV, powered by frequency converter, below the rated frequency and operating at constant torque.
The series has a higher efficiency and wider economic operating range than asynchronous motors of the same specification in the load range of 25% to 120%, with significant energy saving effects. The temperature rise of the motor is low, 40-60K under rated load.
1, high motor power factor, high quality factor of the grid, no need to add power factor compensator, the capacity of the substation equipment can be fully utilised;
2, permanent magnet motor is permanent magnet excitation, synchronous operation, there is no speed pulsation. During dragging fans, pumps and other loads do not increase the pipeline resistance loss;
3, according to the needs of permanent magnet motor can be designed into high starting torque (more than 3 times), high overload capacity, so as to solve the phenomenon of "big horse pulling small cart";
4, the reactive current of ordinary asynchronous motors is generally about 0.5 to 0.7 times the rated current, Mingteng permanent magnet synchronous motors do not require excitation current, the difference between reactive current permanent magnet motors and asynchronous motors is about 50%, the actual running current is about 15% lower than that of asynchronous motors;
5, the motor can be designed to start directly, the shape and installation size is the same as the current widely used asynchronous motor, can fully replace the asynchronous motor;
The series products are widely used in various equipments such as fans, pumps, compressors belt machines refining machines in electric power, water conservancy, petroleum, chemical industry, building materials, metallurgy, mining and other fields.
