Q
What is the reaction of the electric vehicle controller?
2022-06-29 13:57:21.102
Among them, the performance is the most, and the most direct is the inability to drive. 1. The electric vehicle controller is the core component and the component that controls the rotation of the motor. 2. The damage to the microelectronic part of the electric vehicle controller may be very small, mainly because the high-power components such as power tubes and capacitors are damaged more. 3. If the power tube is damaged, commonly known as the burst tube, it will cause the electric vehicle to fail to drive, and the instrument power light will flicker or not light. The electric vehicle motor will have resistance and it will be difficult to implement (don't forcefully push or pull the electric vehicle at this time, it will burn the motor). 4. If the controller is damaged, there will also be a short circuit, the electric vehicle insurance is burned out, or the air circuit breaker trips.
Q
The structure of the motor controller
2022-06-29 13:56:48.283
Electronic control module (ElectronicController) includes hardware circuit and corresponding control software. Hardware circuits mainly include microprocessors and their minimum systems, monitoring circuits for motor current, voltage, speed, temperature and other states, various hardware protection circuits, and data interaction with external control units such as vehicle controllers and battery management systems. communication circuit. The control software implements corresponding control algorithms according to the characteristics of different types of motors.
Q
Motor Controller Troubleshooting and Troubleshooting Steps
2022-06-29 13:56:11.949
First of all, when the motor controller fails, it should check whether the power supply is faulty at the first time, and then adjust the voltage to see if the voltage of the external network is normal, or if the signal light is flashing, and the external plug wire should also check whether there is a short circuit .
Q
There are several types of motor controllers

Small motors can be started with a switch or circuit breaker connected to the power supply, and large motors need to cooperate with a special switching unit, called a motor starter or motor contactor. When starting, a directonline (DOL) starter directly connects the motor to power. A buck starter, Y-delta switching starter, or soft starter uses a voltage drop circuit to connect power to the motor, after which the voltage rises gradually or in stages. Smaller power motor starters are a manually operated switch, while larger motors or applications requiring remote or automatic control generally use magnetic contactors. Medium voltage power sources (around several thousand volts) use circuit breakers as switching elements. The motor starter of direct online (DOL for short) will add all the line voltage to the motor end, which is the simplest motor starter. Starters with direct-on-line start may also include protective elements. Low-power online direct-start starters are manually operated, high-power starters use electromechanical contactors (relays) to switch the motor circuit, and there are online direct-start starters that use solid-state electronics. If the high inrush current of the motor start does not cause excessive voltage drop of the power supply, a starter with direct on-line start is used. The maximum motor power that the starter can work with is also limited by the capabilities of the power supply. For example, some rural power equipment may require motors larger than 10kw to use decompressed motor starters.
Q
How to choose a motor controller
2022-06-29 13:55:11.289
(1) Select the controller type that matches the motor type. Such as DC brush, DC brushless, square wave or sine wave, Hall, no Hall and so on.
