high efficiency:The rated efficiency exceeds the national first-class energy efficiency standard and reaches the national standard IE5 energy efficiency standard.
High power factor:The permanent magnet motor rotor has no induction current excitation, the stator winding presents a resistive load, the motor power factor is above 0.95, and no reactive power compensation is required.
High power saving rate:Depending on the load conditions, instead of asynchronous motors, the comprehensive power saving rate is 15%-30%.
Small current:Compared with 3-phase asynchronous, the current is reduced by more than 20%, and no reactive power compensation is required. When the company plans the layout in the store, it can greatly reduce the investment in cables and transformers.
Low temperature rise:There is no copper loss in the rotor winding, no reactive current in the stator winding, and the temperature rise is lower than that of the asynchronous motor by more than 20k.
Good control performance:The permanent magnet synchronous motor is easy to control, has no speed slip, good dynamic response performance, precise speed control, and has greater advantages in occasions with high speed requirements.

Principle of energy saving
1). The rotor of the permanent magnet synchronous motor uses high-performance rare earth permanent magnet materials to generate a fixed magnetic field (generated by permanent magnets and current), and the rotating magnetic field of the stator drags the rotor magnetic field (rotor) to rotate, so the rotational speed of the rotor must be equal to the synchronous speed, and no excitation current is required , excitation winding, to achieve high energy efficiency.
2). The asynchronous motor generates induced current in the rotor through the rotating magnetic field of the stator to generate electromagnetic torque. The magnetic field is not directly generated in the rotor, so the rotor must be lower than the synchronous speed.
3). The power density of permanent magnet motors is about 30 percent higher than that of asynchronous motors of the same power. For motors of the same power, permanent magnet motors are 1-2 frame sizes smaller than asynchronous motors. Small size means small iron loss and mechanical loss Small.
4). The permanent magnet synchronous motor has higher efficiency than the asynchronous motor of the same power, and at the same time, the high-efficiency zone is wider. When the speed range of the permanent magnet synchronous motor is 25%-100% of the rated speed, the efficiency runs in the high-efficiency zone, while the speed range of the asynchronous motor , below 70 percent of the rated speed, the efficiency will drop sharply.
core value
1). Rare earth permanent magnet
The main magnet of the 3.0 permanent magnet aerator adopts neodymium iron boron with a value of "1 million yuan\/ton".
2). Constant speed
The motor speed is not affected by voltage fluctuations. When the voltage is weakened to 300V or increased to 400V, its speed remains at 1500 rpm, and the speed will not change due to voltage changes.
3). Low temperature rise
The permanent magnet synchronous motor has a small operating current, so the temperature rise is low, the service life is long, and the reliability is higher.
