There are two ways to change the speed of an induction motor

1. Change the terminal voltage of the stator.

2. Change the frequency of the stator. The output torque of a new energy vehicle motor can vary with the terminal voltage of the stator. Note that changes in voltage will not change the speed difference corresponding to the maximum torque of the motor.

The principle of controlling the motor speed by changing its operating frequency is based on the relationship between frequency and synchronous speed: e=4/p, e varies with f.

The power electrical converter drives the induction motor to rotate, and the conversion device converts the constant voltage provided by the outside into variable voltage with different amplitudes and frequencies based on the requirements of motor torque and speed.

Characteristics of Induction Motors

1. Small and lightweight.

2. Easy to achieve high-speed rotation with a speed exceeding 10000r/min.

3. High operating efficiency at high speed and low torque.

4. High torque and wide speed control range at low speeds.

5. High reliability (robustness).

6. Low manufacturing cost.

7. Simplification of control devices.

The rotor in an induction motor does not have a specific electrical connection.

In specialized electric vehicle motors, it is best to meet the above conditions. Asynchronous motors meet these conditions to a certain extent. Asynchronous motors have low cost and high reliability, and even if the inverter is damaged and short circuited, it will not generate reverse electromotive force, so there is no possibility of sudden braking. Therefore, it is widely used in large and high-speed electric vehicles. In order to meet the above requirements, major companies have conducted research and developed various asynchronous motors with unique characteristics. In general, as a specialized electric motor for electric vehicles, due to limited installation conditions and the requirement for small and lightweight, when the motor operates at high speeds above 10000r/min, it mostly uses a first stage gear reducer to achieve deceleration. In addition, vibration makes the working environment very harsh, requiring high torque at low speeds and constant output power over a wide speed range. Therefore, asynchronous motors for electric vehicles are different from general industrial motors, and various new methods are adopted in their design.
