Typical application of permanent magnet synchronous motor
1. Electro-hydraulic servo injection molding machine application program
The traditional injection molding machine uses a three-phase asynchronous motor with a fixed-quantity pump. During the operation of the injection molding machine, the motor needs to operate for a long time. Through the energy-saving transformation of the servo oil pump drive system, the rapid response of the permanent magnet synchronous motor and the large starting torque can start the permanent magnet synchronous motor to drive the oil pump to generate pressure when the injection molding machine needs to complete the injection molding, in the process of cutting and clamping. The main motor of the oil pump is in a stop state, achieving intermittent zero power consumption, and the energy saving rate can be up to 85% by comparison.
Under the control of excellent servo motor algorithm, the noise is much lower than that of the ordinary injection molding machine. In the ideal state of configuring a low-noise screw pump, the noise of the injection molding machine is less than 70 decibels, achieving silent operation and improving the working environment.
2 Energy-saving applications on iron ore dry sorter
The use site is a mining site in the northwest, with a dusty environment. The equipment uses a total of 125 electric motors. When the lifting equipment starts, it needs a large starting torque. In normal operation, the long-term operation of the motor is in the light load state of 30%~50% of rated power. The efficiency of the original three-phase asynchronous motor is used. It is only about 65%, the power factor is about 0.4 to 0.6, causing serious energy waste. The permanent magnet synchronous motor is used, and the energy saving effect is very obvious.
