The motor wiring position (according to the seat number) is divided into two structures (see installation and dimensional drawings): the side of the seat and the top of the seat for the user's choice (if the user does not specify, the wiring box is on the right side). The rated frequency of this series of products is 50Hz, and the rated voltage is 380V or 660V, with self-starting capability and also variable frequency starting, and can be switched to the grid after variable frequency starting. The temperature rise of the motor is low, 30-50K under rated load. This series of products can completely replace Y2, Y3, YE2 and other series of low-voltage asynchronous motors,Can be designed with different cooling methods, voltage level of customised products according to customer demand to increase the power density, the design of the lower base number.
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 and belt machines in the fields of electric power, petroleum, metallurgy, textile and building materials.

What are the motor nameplate data? The nameplate of the motor is labeled with important parameters of the motor, including at least the following information: name of manufacturer, motor name, model, protection class, rated power, rated frequency, rated current, rated voltage, rated speed, thermal classification, wiring method, efficiency, power factor, factory number and standard number, etc. What are the advantages of Mingteng PM motors over other brands of PM motors? 1.The level of design is not the same The company has a professional R & D team of more than 40 people, after 16 years of technical experience accumulation, has a full range of permanent magnet synchronous motor R & D capabilities, according to customer requirements for special design, can meet the needs of a variety of equipment. 2.The materials used are not the same The company's permanent magnet motor rotor permanent magnet material adopts high magnetic energy product and high endowment coercive force sintered NdFeB, conventional grades are N38SH, N38UH, N40UH, N42UH, etc. Our company promises that the annual demagnetization rate of the permanent magnets is not higher than 1‰. The rotor lamination adopts high specification lamination materials such as 50W470, 50W270, and 35W270, with silicon steel sheets pressed together to reduce losses. The company's molded coils all use sintered wire, high voltage resistance to withstand stronger, bulk winding all use corona 200 degrees of electromagnetic wire. 3.Rich in Cases The company's products are used in iron and steel, coal, cement, chemical, petroleum, mining, metallurgy, building materials, rubber, textile, paper, transportation, electric power, medicine, metal calendering, food and beverage, water production and supply and other industrial and mining fields, with a wealth of use cases.
