What are the basic requirements for new energy vehicle motors?

1. The motor has a compact structure, small size, and limited packaging size, so it must be specially designed according to the specific product.

2. Lightweight to reduce the overall weight of the vehicle. Aluminum alloy casing should be used as much as possible, and the rotational speed should be high to reduce the weight of the entire vehicle, increase the compatibility between the motor and the vehicle body, expand the available space of the vehicle body, and thus improve the comfort of riding.

3. High reliability and controllable failure modes to ensure the safety of passengers.

4. Provide precise torque control with good dynamic performance.

5. High efficiency and high power density. To ensure high efficiency within a wide range of speed and torque, in order to reduce power loss and increase the driving range of a single charge.

6. Low cost to reduce the overall cost of vehicle production.

7. Wide speed regulation range. It should include a constant torque zone and a constant power zone, with a high output constant torque during low-speed operation to meet the requirements of fast starting, acceleration, and load climbing of the vehicle; High speed operation outputs constant power and has a large speed regulation range to meet the requirements of high-speed driving such as flat roads and overtaking.

8. High instantaneous power and strong overload capacity. To ensure that the car has 4-5 times the overload capacity to meet the requirements of short-term acceleration and steep hill climbing.

9. Good environmental adaptability. It is necessary to adapt to the different regional environments in which the car operates, and be able to work normally even in harsh environments, with good resistance to high temperatures and humidity.
