The stator structure of the high-voltage and high-efficiency asynchronous start large permanent magnet synchronous motor is similar to that of the ordinary Y series high-voltage asynchronous motor. The motor adopts modern high-performance motor design theory and design technology to optimize the core and winding; the rotor is placed in the high-function rare earth “magnetic king”, which optimizes the squirrel cage structure and can generate higher starting speed than ordinary asynchronous motor at rated voltage and rated frequency. Torque.
The large permanent magnet synchronous motor rotor adopts rare earth "Magnetic King" energy-saving material, which is recognized as the world's highest permanent magnet material with magnetic energy product, and exhibits "permanent magnetic field" through saturation magnetization. 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.
The high voltage large permanent magnet synchronous motor has a high power factor. 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. This is the basic working principle of asynchronous start permanent magnet synchronous motor.
The large permanent magnet synchronous motor is a high voltage asynchronous starting permanent magnet synchronous motor. It is based on the technical conditions and development design of the TYCKK series (IP44) high efficiency and high voltage permanent magnet synchronous motor in China JB/T 12681-2016 standard.
Large-scale high-voltage high-efficiency permanent magnet synchronous motor adopts high-function "Magnetic King" rare earth permanent magnet material, establishes air gap magnetic field, converts electric energy into mechanical power output, and drives industrial load; due to the use of rare earth high-function permanent magnet material, the product establishes working air gap magnetic field It does not need to draw the reactive excitation current from the power supply, and its power factor is above 0.96. The efficiency is generally increased by 2%-8% compared with the Y series high-voltage asynchronous motor, especially the efficiency increases rapidly with the load increase, and the load is 25%-120% wide. Maintaining high efficiency in the range, this type of permanent magnet synchronous motor products has entered the recommended catalogue of high efficiency and energy saving motors in China.
The large asynchronous start permanent magnet synchronous motor adopts the "no difference replacement" design technology with the Y series high voltage motor. The product corresponds to the voltage level of the Y series high-voltage motor, the installation size corresponds to the “no difference” replacement; at the rated voltage and rated frequency, it has self-starting capability, synchronous operation and no slip.
