Motor Permanent Magnet Motor Offering Speed Range 0-8000 RPM Designed for Electric Vehicles and Renewable Energy Systems

This motor reduces energy consumption by up to 30% compared to traditional induction motors powered by inverters. It maintains high efficiency across a wide range of loads—from 20% up to 110% of the rated capacity—resulting in energy savings between 10% and 40% in real-world applications.

Additionally, it achieves an exceptionally high power factor, close to 1.0 at rated load, and always above 0.95. This high power factor minimizes stator current and reduces copper losses, enhancing overall energy efficiency.

The motor delivers consistent torque across a broad range of speeds without the need for forced ventilation. It is ideally suited for applications that require speed variation while maintaining constant torque, even at low speeds. Moreover, this motor operates effectively without the need for an encoder.

Equipped with bearings that provide an L10 lifespan of up to 100,000 hours—equivalent to more than ten years of continuous use—this motor ensures reliability and durability. The inclusion of grease nipples allows for easy re-lubrication, significantly reducing maintenance-related downtime.

The motor utilizes powerful rare-earth magnets made from Neodymium, Iron, and Boron (NdFeB), which are approximately eighteen times stronger than conventional ferrite magnets. These magnets are coated with a protective epoxy layer, enhancing mechanical strength and resistance to corrosion.

Embedded PTC (Positive Temperature Coefficient) thermistors in the windings safeguard the motor against overheating caused by phase loss, overload conditions, and voltage irregularities. This integrated thermal protection significantly improves operational safety and reliability.

As a synchronous motor, the rotor speed synchronizes perfectly with the rotating magnetic field of the stator, eliminating slip and rotor power losses. This results in highly stable speed performance that remains unaffected by changes in load or voltage, thus enhancing control accuracy.

The motor employs a maximum torque/current ratio control mode that maintains a high power factor throughout its entire speed range. This approach reduces stator current by 15% to 30%, which in turn decreases cable transmission losses and effectively increases cable capacity.

Thanks to its high efficiency and reduced losses, the motor’s temperature rise is 15 to 20°C lower than that of comparable asynchronous motors operating under the same conditions. This lower temperature rise contributes to longer motor life and better performance.

This motor is widely used across various industries, including injection molding machines, air compressors, pipe making equipment, hydraulic machinery, food processing machines, extruders, wire drawing machines, and pharmaceutical manufacturing equipment. It must be paired with a dedicated permanent magnet motor inverter for optimal performance.

Switching from a 37kW IE2 (GB3) induction motor to this advanced motor can yield substantial energy cost savings—about 9,000 RMB annually based on continuous 24/7 operation. This makes it a cost-effective solution for industries aiming to reduce operational expenses.
