Permanent Magnet Synchronous Motor

The permanent magnet synchronous motor product is developed and manufactured according to China JB/T 13297-2017 "TYE4 series three-phase permanent magnet synchronous motor technical conditions", and the efficiency meets the energy efficiency standard of GB30253-2013 "Permanent magnet synchronous motor energy efficiency limit value and energy efficiency grade". To achieve the international advanced level of similar products, listed in the first batch of high-efficiency and energy-saving motor promotion catalog of China National Development and Reform Commission.

The stator structure of the low voltage high efficiency permanent magnet synchronous motor is similar to that of the ordinary Y series asynchronous motor. Using modern high-performance motor design theory and design technology, the core and winding are optimized; the rotor is placed in the high-performance rare earth “magnetic king”, which optimizes the squirrel cage structure and can generate a higher starting speed than an ordinary asynchronous motor at rated voltage and rated frequency. Moment.

Rare earth "Magnetic King" is recognized as the world's highest permanent magnet material with magnetic energy content, saturated magnetization, and presents a "permanent magnetic field". After the motor is installed, the reactive current is not required, and the permanent magnetic field of the "Magnetic King" interacts with the three-phase current of the winding to generate a stable electromagnetic torque to drive the load.

This structural feature of the permanent magnet synchronous motor makes the power factor high. Under the condition of ensuring the same output power, the current is significantly reduced, the resistance loss of the winding is reduced, and there is substantially no rotor loss during operation, which exhibits remarkable high efficiency and energy-saving characteristics. Due to the reduction of the total loss, the temperature rise is reduced by more than 30K compared with the conventional asynchronous motor, and the operating life is prolonged.

The permanent magnet synchronous motor product series is a three-phase fully enclosed self-fan air-cooled motor. The protection grade of the motor is IP54, the installation form is IMB3, and the working system is S1. It can meet the user's requirements for other voltage levels (415V/690V/1140V), protection level, cooling method, installation form, etc. When the motor speed is higher than 1500 rpm (less than 500 rpm), the inverter is used for power supply.

The universal permanent magnet synchronous motor adopts the "no difference replacement" design technology with the IE2 and IE3 series motors. Corresponding to the voltage level of IE2/IE3 series motor, corresponding to the installation size, it can realize “no difference” replacement; at rated voltage and rated frequency, it has self-starting capability, synchronous operation and no slip.

The high efficiency permanent magnet synchronous motor uses Class F insulation. There is an oil draining device above the frame number H180. If the user requires the stator to measure temperature, the working mode is S1, which is a fully enclosed, self-fan cooling structure. Cooling method is IC411, the enclosure protection grade is IP54, and can produce "W" outdoor, "TH" wet tropical, "WTH" outdoor wet tropical, "W (F1 - F2)" anti-corrosion type (F1 is medium anti-corrosion, F2 For strong anti-corrosion), the explosion-proof type, the heat sink of the motor is vertically and horizontally distributed, and the position of the motor junction box (by the frame number) is divided into two structures (see installation and dimension drawing) for the user to choose. Use (the junction box is on the right side when not specified by the user).

The rare earth permanent magnet synchronous motor has the advantages of novel design, compact structure, beautiful appearance, high efficiency and torque, good starting torque performance, energy saving, low noise, small vibration and safe and reliable operation. This series of motors are widely used in industrial and mining enterprises such as petrochemical, electric power, transportation, textile, etc., and are used to drive various machines such as fans, pumps, compressors, belt conveyors and machine tools.
