Pure electric vehicle, single motor or dual motorPure electric vehicles had their advantages and disadvantages.
In terms of performance, the dual-motor power performance was stronger, the vehicle accelerated faster, and the push back feeling was more obvious. There were three types of dual motor driving methods. The common method was to use two single motor with different power to control the operation of the car at high speed and low speed respectively to improve work efficiency. It could effectively improve the performance and endurance of the car, and the user experience was better. In order to cope with climbing and complicated road conditions, the motor power of the single-motor system was often large, but in actual applications, most of them were running at low speeds, which was inefficient and wasted more energy. However, the single-motor version of the Tesla Model 3 rear-bridge permanent magnet motor had a power of 202 Kilowatts, which was considered a high-power motor, which also allowed the vehicle to have better acceleration.
In terms of cost and endurance, due to the complicated operation process of the dual motor, it was necessary to coordinate the balance and control between the two motor. The technical requirements were high, the cost of building a car was greatly increased, and the endurance of the dual motor might be reduced. The cost of a single motor was relatively low. In the case of limited budget or low requirements for driving experience, mainly used for urban commutes, a single motor was a more cost-effective choice.
From the perspective of energy efficiency, the dual motor had more advantages than the single motor in terms of energy conversion efficiency. Using different power motor at low and high speeds could greatly improve energy utilization efficiency and save energy and environmental protection.
Therefore, choosing a single motor or dual motor for a pure electric vehicle required comprehensive consideration of individual performance, budget, endurance, and energy efficiency.

The difference between single-phase motor and three-phase motorThe principle difference between a single-phase motor and a three-phase motor is as follows:
1. * * Power supply **: Single-phase electricity consists of a live wire and a neutral wire. Single-phase electric motor uses single-phase power. Three-phase electricity has three phase lines, which are three-phase four-wire (three live wires and one zero wire). Three-phase electric motor uses three-phase power.
2. * * Stator winding structure and distribution **
- * * Three-phase motor **: Stator winding is composed of three-phase winding with a difference of 120 electrical angles in physical space. After the three-phase symmetrical alternating current was introduced, a theoretically circular rotating magnetic field was formed. The rotating magnetic field cuts the winding of the motor, and an induced current is generated in the winding of the motor. The current carrying conductor of the motor generates electromagnetic force under the effect of the rotating magnetic field of the motor, and the direction of rotation of the motor is the same as the direction of the rotating magnetic field.
- * * Single-phase motor **: Stator winding is generally composed of a main winding and a secondary winding (taking a single phase motor as an example). The main winding and the starting winding were separated by 90 degrees in space. The starting winding was connected in series with a suitable capacity, so that the current of the main winding was approximately 90 degrees different in phase, forming a phase-splitting or phase-shifting principle. Two currents that were 90 degrees different in time and space were passed into the two winding, creating a rotating magnetic field that automatically started the generator. After starting, the speed of the engine will rise to a certain level, and the starting winding will be disconnected with the help of a centrifugal switch or other automatic control device. Only the main winding will work during normal operation.
3. * * The influence of the rotating magnetic field on the activation **
- * * Three-phase motor **: The three-phase power supply can be directly connected to the three-phase winding to generate a rotating magnetic field. This rotating magnetic field can make the motor start and run smoothly without the need for additional auxiliary devices (such as a transformer) to generate a rotating magnetic field.
- Single-phase motor: When a single-phase Sinusoid current flows through the winding, it produces an alternating pulsating magnetic field. It can be seen as two rotating magnetic fields with the same speed and opposite directions. This makes the motor unable to rotate when the motor is at rest due to the two equal and opposite torques. Therefore, a special method was needed to generate a rotating magnetic field to start, such as adding a starting winding to the stators and connecting the starting winding in series (a single phase motor), or using the shaded pole method (a shaded pole motor).
4. * * Field of application **: Single-phase motor is more used in living places, and three-phase motor is mostly used in industrial fields.

How to connect a single-phase motor to a four-wire motorThere were two ways to connect the four wires of a single-phase motor, the star connection and the triangle connection. Star connection is mainly used for low-power motor, starting current is small, but starting moment is also small; triangle connection is mainly used for high-power motor, starting current is large, but starting moment is also large. You can check the label on the motor shell or check the motor manual to determine the motor's connection method. Generally speaking, the star connection is marked with "Y" or "Delta/Y", and the triangle connection is marked with "Delta" or "Y/Delta".
It should be noted that among the four wires of the single-phase motor, the main wire is the power supply wire of the motor, and the auxiliary wire is used to start the motor. There were four wires because the single-phase motor needed to be started by a starting reactor or a starting reactor. These starting components needed to be connected to the motor, thus increasing the number of wires in the motor. If the four wires of the single-phase motor were connected wrongly, it might cause the motor to fail to start normally or damage the motor. If you find that the connection is wrong, you should stop using it in time and ask a professional to repair and correct the connection.
