A high-efficiency motor refers to a high-efficiency motor whose efficiency should meet the corresponding energy efficiency requirements. High-efficiency motors integrate new manufacturing processes and new materials perfectly into the core components. The optimized design of the motor coil can effectively reduce the loss of electromagnetic energy, thermal energy and mechanical energy, and improve the operation efficiency. The motor generates less heat and has a long service life.

Ultra-efficient motors improve at every energy loss:

1. Optimized design reduces mechanical loss △ Po• High quality ball bearing, reduces friction and vibration• Locked bearing reduces end clearance• Fan and fan cover are designed for proper cooling and quieter operation• Smaller fan produces smaller losses • Lower motor operating temperature allows smaller fans to be used

2. Optimized design reduces stator copper loss △ PCu1• More windings• Improved slot design• ISR (Inverter Spike Resistant) magnet wire provides up to 100 times higher voltage peak resistance• Both ends of the motor stator have terminals External strapping • Low temperature rise (< 80°C) • Class F insulation system • Double insulation life for every 10°C lower operating temperature at the maximum allowable temperature limit

3. Optimized design reduces rotor copper loss △ PCu2 and mechanical loss • Improves rotor insulation • High pressure die cast aluminum rotor • Rotor dynamic balance

4. Design reduces iron loss △ PFe1 • Thinner silicon steel lamination • Improved steel properties to achieve lower loss and provide the same performance • Optimized air gap

Features

1. It saves energy and reduces long-term operating costs. It is very suitable for textiles, fans, pumps and compressors. The cost of motor purchase can be recovered by saving electricity for one year;

2. The asynchronous motor can be completely replaced by starting directly or adjusting the speed with a frequency converter;

3. The rare earth permanent magnet high-efficiency energy-saving motor itself can save more than 15℅ of 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 the transmission and distribution capacity and prolongs the overall operating life of the system;

6. Power saving budget: Take a 55kw motor as an example, a high-efficiency motor saves 15℅ of electricity than a general motor, and the electricity fee is calculated at 0.5 yuan per kilowatt-hour (general residential electricity). cost.

advantage：

Direct start, the asynchronous motor can be completely replaced.

The rare earth permanent magnet high-efficiency energy-saving motor itself can save more than 3℅ of electric energy than ordinary motors.

The power factor of the motor is generally higher than 0.90, which improves the quality factor of the power grid without adding a power factor compensator.

The motor current is small, which saves the transmission and distribution capacity and prolongs the overall operating life of the system.

Adding a driver can realize soft start, soft stop and stepless speed regulation, and the power saving effect is further improved.
