The underlying logic of choosing PMSM
In the powertrain of pure electric vehicles, the permanent magnet synchronous motor is one of the most widely used motor types. It has been widely adopted in the market because it achieves a good balance in terms of efficiency, power density, and low-speed torque response, and these three aspects directly determine the vehicle's range, overall layout, and driving experience.
To determine whether it is truly suitable for your vehicle, you need to first assess your operating conditions. For our permanent magnet synchronous motor, its application scenarios include micro vehicles, tricycles, and construction machinery platforms. We have specially designed for these scenarios to ensure that it can still perform at its best in more demanding working conditions.
PMSM Motor in EV: Why It Outperforms Alternatives
The rotor of the permanent magnet synchronous motor is equipped with permanent magnets, and the magnetic field is always present. The rotor does not require induced current, and thus there is no rotor copper loss, which is one of the advantages over other types of motors. This enables the motor to maintain high efficiency over a wide range of speeds, rather than performing well only under specific conditions. For frequent start-stop urban conditions and continuous load construction machinery scenarios, this efficiency advantage will be particularly significant.
Power density is the second reason. With the same output power, the PMSM is lighter in volume and weighs less. A well-designed permanent magnet synchronous motor can output more torque in a relatively compact volume.
Taking our 96V high power density PMSM for electric vehicle application as an example, it can output competitive peak torque without forcing a major change in the axle layout. Our 96V platform achieves a peak of 15kW, a peak torque of 65Nm, and a peak speed of 7500rpm within the 60-108Vdc operating range. It covers the needs of different types of vehicles while achieving lightweight design, leaving more space for the vehicle's layout and load capacity.
PMSM Motor for Electric Car: The Flat-Wire Design Realizes Efficiency Advantages
The efficiency advantage of the permanent magnet synchronous motor largely depends on the winding design. Compared to traditional round wires, the flat-wire winding has a higher slot fill rate and shorter ends, thus outputting higher efficiency and shorter axial length in the same volume. This is the core value of the hairpin winding PMSM motor in the EV powertrain solution.
Our permanent magnet synchronous motor adopts this flat-wire design. Through the coordination of conductor geometry design and heat dissipation path, the AC copper loss in the high-speed zone is controlled within a reasonable range, allowing this 96V pure electric power platform to maintain stable output at a peak speed of 7500rpm. We do not regard the system lightweighting and high power density as mere promises, but rather through the collaborative optimization of winding design, magnetic circuit design, and structural design, each parameter can be verified in real-world conditions, making the product truly lightweight and efficient.
