What Characteristics Should An Electric Car Motor Have?

Electric vehicles are the trend in the automotive industry, and we all know that the principle is to replace the engine with an electric motor to achieve electric drive. Does this mean that the electric motor on an electric car is the same as an ordinary electric motor? Without a doubt, the answer is no. The performance standards and driving principles of electric vehicle motors are different from those used in traditional induction motors. Next, we will introduce the characteristics that electric vehicle motors should have

1. In order to meet the needs of frequent starting and stopping, acceleration and deceleration or hill climbing of electric vehicles, electric vehicle motors should have a large starting torque, good starting performance and good acceleration performance. In terms of speed or torque control, the requirement for motor response time is reflected in the motor test. At the same time, when the external load changes and a step change occurs, the motor must quickly reflect this change to change its output power and speed.

2. In order to match the torque output of the electric vehicle at high speeds and to ensure that the vehicle can reach its maximum speed, the constant power range of the motor should be designed to be wider.

3. In order to be able to modify the driving speed and related driving force of the electric car at any time according to the driving needs, the electric car motor should have a wide speed regulation capability, with high torque at low speed and high power at high speed.

4. To achieve optimum efficiency, the EV motor should have strong efficiency characteristics over a wide speed/torque range. This will also increase the continuous driving range after charging, which typically requires an efficiency of 85% to 93% in the normal driving cycle area.

5. Electric vehicle motors have the best power density, lightest mass and smallest form factor requirements

6. Electric vehicle motors need to be reliable, have high moisture and temperature resistance, be able to run for long periods of time in difficult environments, operate with low noise and be simple to maintain.

7, the effectiveness of the motor controller to be able to recover braking energy.
