High-efficiency and energy-saving motors adopt new motor design, new technology and new materials to improve output efficiency by reducing the loss of electromagnetic energy, thermal energy and mechanical energy. Compared with ordinary motors, the energy-saving effect of using high-efficiency motors is very obvious. Under normal circumstances, the efficiency can be increased by 4% on average. The weight is basically the same.
High-efficiency and energy-saving motors refer to general-purpose motors with high efficiency.
Features of high efficiency and energy saving motors:
1. It saves energy and reduces long-term operating costs. It is very suitable for textiles, fans, pumps, and compressors. It can recover the purchase cost of the motor by saving electricity in one year.
2. The asynchronous motor can be fully replaced by starting directly or using the frequency converter to adjust the speed.
3. The rare earth permanent magnet high-efficiency energy-saving motor itself can save more than 15℅ electric energy than ordinary motors.
4. The power factor of the motor is close to 1, which improves the quality factor of the power grid without adding a power factor compensator.
5. The motor current is small, which saves transmission and distribution capacity and prolongs the overall operating life of the system.
