Permanent Magnet Motor Product Description:

This series of motors is specially designed to consider the special working conditions of the compressor, with high efficiency, low noise, strong overload capacity, long bearing life, and so on. The performance and installation size of this series of motors conforms to the lEC60034 standard, DIN42673 standard, GB755 standard, and related professional and technical standards. And the company has passed IS09001 international quality system certification many times.

From the order, development, manufacturing, inspection, sales, and service process in accordance with the requirements of IS09001 quality system control. This series of motors consider that the cable of the motor is directly connected to the electric control box of the compressor. According to the user's requirements, the motor can be equipped with extended lead wire and screw sleeve; This series of motors features a rotor with a permanent magnet. This technology offers significant advantages to the motor, such as higher efficiency, power factor, and higher power density.

They are driven by frequency converters that provide constant torque over a wide range of speed changes and operate even at low speeds with higher efficiency than induction motors. In addition to the energy efficiency of IE4, the motors can better achieve the efficiency of IE5 on the market today.

Demonstration of advantages:

1. Greater power density - reduced mass and volume
Permanent magnets inserted into the rotor ensure a considerable reduction in electrical losses, thereby reducing the motor temperature and making it possible to use a smaller housing size. The mass and volume of an equivalent motor are reduced by 70% compared to an induct motor with the same output power and speed. The shaft and bearings of the motor can withstand higher power and torque in a smaller housing size.

2. The motor provides superior efficiency at a full range of speeds or loads
The motor offers excellent efficiency regardless of speed or load, saving up to 30% of energy compared to inverter-driven induction motors.

3. Maintain constant torque in a wide range of speed regulation
The motor can operate with constant torque over a wide speed range. This feature makes it ideal for applications that require speed variations and constant torque, even at low speeds, without the need for an encoder. The motor is able to operate at up to 30% higher than its rated speed without the use of special components.

4. Permanent magnets
Electric motors use powerful permanent magnets. These magnets are a combination of neodymium, iron, and boron (NdFeB), commonly known as rare-earth magnets. They are 18 times stronger than traditional ferromagnets. To provide excellent mechanical strength and corrosion resistance.NdFeB magnets are covered with a protective epoxy resin coating

5. Thermal protection device

Motor windings built-in PTC(positive temperature coefficient)thermistor, or PT100 platinum thermistor, can provide comprehensive protection against overheating due to lack of phase, overload, and under voltage or overvoltage.

6. Bearing life up to 100,000 hours
The motor is equipped with bearings that can provide up to 100,000 hours of L10 life. All motors are equipped with open bearings and endcaps with refueling nozzles that allow for re-lubrication, thus reducing downtime for maintenance.

7. Universal features:
A strong and versatile foot makes motor calibration and installation easier. The rigid cast iron construction provides high mechanical strength and low vibration ratings. The fully enclosed structure can be used in a variety of harsh working conditions. it can be used with inverters from many manufacturers at home and abroad.
