How to debug the electric vehicle with the wrong phase?

The phase lines are 60 and 120, some controllers can be changed, some can't, you can flip the hall in the middle of the motor, and it's 60 degrees face up, and it's 120 degrees down.

If the motor is reversed, we have to stop the adjustment temporarily. We empirically need to phase the line.

The green does not move, the blue and yellow positions are reversed, and the yellow of the Hall line is not changed, and the blue and green are reversed.

The thick line is yellow and blue-green.

Connect green, blue to yellow, thin wire, yellow to yellow, green to blue, blue to green, and you're good to go. The latter two are the yellow phase line immobile blue-green counterpoint, and the fine Hall line green immobile blue-yellow counterpoint. The thick phase line blue does not move, the yellow-green counterpoint is fine, the hall blue does not move, and the yellow-green counterbalance.

The damage of power devices generally has the following possibilities:

1. Caused by motor damage; Caused by poor quality or insufficient selection grade of the power device itself; Caused by loose device installation or vibration; caused by motor overload; Caused by damage to the drive circuit of the power device or unreasonable parameter design.

2. The damage of the internal power supply of the controller generally has the following possibilities: short circuit of the internal circuit of the controller; Short circuit of peripheral control components; Short circuit in the external leads.

3. The controller works intermittently, and there are generally the following possibilities: the parameters of the device itself drift in a high or low temperature environment; The overall design power consumption of the controller is high, which leads to the high local temperature of some devices and the device itself enters the protection state. Poor contact.

The circuit mainly includes the following parts: control chip and its drive system, AD sampling system, power module and its drive system, hardware protection system, position detection system, bus support capacitor, etc.

The power main circuit adopts a three-phase inverter full bridge, in which the main power switching device is IG-BT. In the high-current, high-frequency switching state, the capacitor is electrolytic.

The stray inductance to the power switch module has a great impact on the energy consumption of the power circuit and the peak voltage on the module, so the stacked bus substrate is used to make the stray inductance of the circuit as small as possible to adapt to the characteristics of low voltage and high current operation of the control system.

Summary. Hello <>

If the original electric vehicle with the same phase does not move, there are several reasons:1Battery issues:

Electric vehicles are powered by batteries, and if the battery is not charged or is undercharged, the electric vehicle will not start. You can check if the battery is well connected and if the battery is sufficient. 2.

Motor failure: The motor of the electric vehicle is responsible for turning the wheels, and if the motor fails, the electric vehicle will not be able to operate. You can check if the wiring of the motor is disconnected, or if the motor needs to be repaired or replaced.

3.Control system failure: The control system of the electric vehicle includes components such as controllers and sensors, and if the control system fails, the electric vehicle will not be able to start.

You can check whether the wiring of the control system is working properly and whether the sensors are working properly. 4.Other failures:

In addition to the above common causes, there are also other component failures, such as brake failure, drive system failure, etc.

The phase is the same, why doesn't the original electric car move.

Motor failure: The motor of the electric vehicle is responsible for turning the wheels, and if the motor fails to shout, the electric vehicle will not be able to operate. You can check if the wiring of the motor is disconnected, or if the motor needs to be repaired or replaced.

3.Control system failure: The control system of the electric vehicle includes components such as controllers and sensors, and if the control system has a Zhenglun failure, it will cause the electric vehicle to fail to start.

You can check whether the wiring of the control system is working properly and whether the sensors are working properly. 4.Other failures:

In addition to the above common causes, there are also other component failures, such as brake failure, drive system failure, etc.

If you are buying an electric vehicle new, check the instruction manual first to make sure that the operation method is correct. - Check if the fuse of the electric vehicle is blown and replace it if necessary. - If the electric vehicle is not used for a long time, it will cause the battery to discharge naturally, you can try to charge the battery for a while before starting it.

If the electric car suddenly stops working during the morning car, it is due to the trigger of overload protection, and it can be amused to wait for a period of time before restarting.

If the original electric vehicle with the same phase does not move, first check whether the key components such as the battery, motor and control system are normal.

First of all, we have to let the motor rotate normally, usually the Hall plug is plugged in directly, and the motor line is adjusted. The following gives 6 kinds of laws and regulations to imitate, and there must be 1 kind of motor that can make the motor run normally:

1. The motor line is blue to the controller blue, the motor line is green to the controller, and the motor line is yellow to the controller.

2. The motor line is blue to the controller blue, the motor line is green to the controller is yellow, and the motor line is yellow to the controller green.

3. The motor line is yellow to the controller yellow, the motor line is blue to the controller is green, and the motor line is green to the controller blue.

4. The motor line is green to the controller green, the motor line is blue to the controller is yellow, and the motor line is yellow to the controller blue.

5. The motor line is blue to the controller is yellow, the motor line is yellow to the controller is green, and the motor line is green to the controller blue.

6. The motor line is yellow to the controller blue, the motor line is blue to the controller green, and the motor line is green to the controller yellow.

Controllers

Controller (English name: controller) refers to the main command device that changes the wiring of the megalumin main circuit or control circuit and changes the resistance value in the circuit to control the start, speed regulation, braking and reverse of the motor according to a predetermined sequence.

Consisting of a program counter, an instruction register, an instruction decoder, a timing generator, and an operation controller, it publishes commands"Decision-making bodies", that is, to complete the coordination and command of the operation of the entire computer system.

The fifth and sixth cases are reversed as well! Hall A and C are reversed, and the motor line does not dare to be reversed, for fear of burning Hall.

6 regular connection methods are given, and any one can be selected to adjust the phase of the electric vehicle controller and the motor.

Motor Wire Blue vs. Controller Blue Motor Wire Green vs. Controller Green Motor Wire Yellow vs. Controller Yellow.

Motor Wire Blue to Controller Blue Motor Wire Green to Controller Yellow Motor Wire Yellow to Controller Green.

Motor Wire Yellow to Controller Yellow Motor Wire Blue to Controller Green Motor Wire Green to Controller Blue.

Motor line green to controller green motor line blue to controller yellow motor line yellow to controller brother slow blue.

Motor Wire Blue vs. Controller Yellow Motor Wire Yellow vs. Controller Green Motor Wire Green vs. Controller Blue.

Motor Wire Yellow vs. Controller Blue Motor Wire Blue vs. Controller Green Motor Wire Green vs. Controller Yellow.

Generally, the controller is placed on the top, and the motor is placed on the bottom, and we can remember it like this.

Color to color.

Blue to blue, the other 2 colors are reversed.

Yellow to yellow, the other 2 colors are reversed.

Green to green, the other 2 colors are reversed.

Blue on the top and yellow on the bottom, and the other 2 colors on the other.

Yellow on the top and blue on the bottom, and the other 2 colors are on the other.

Hall has positive and negative, indicating that the motor is a 60° phase angle, and no positive and negative is a 120° phase angle. You can put it in as it is (you can fix it with 502 instant glue slightly), connect the positive and negative electrodes of the three halls in parallel respectively, and connect them with the thin rock and red and black wires in the motor lead wire and weld them (pay attention to insulation), and connect the signal wires of the three halls with the thin yellow, green and blue wires in the motor lead wire respectively and weld (pay attention to insulation).

Measure the Hall truth signal to determine the phase angle of the brushless motor.

The number of magnets for brushless motors is generally 12, 16 or 18, and the corresponding number of stator slots is 36, 48 or 54. When the motor is at rest, the magnetic field lines of the rotor magnet have the characteristic of walking along the minimum direction of magnetic resistance, so the position where the rotor magnet stops is exactly the position of the salient pole of the stator groove.

The magnet does not stop at the center of the stator groove, so there are only a limited number of positions where the rotor and stator are relative to each other, 36, 48 or 54. Therefore, the minimum magnetic pull angle of a brushless motor is 48° or 360 54°.

The Hall element of the brushless motor has 5 envy mold leads, which are the common power supply positive pole, the common power negative pole, the A-phase Hall output, the B-phase Hall output and the C-phase Hall output. We can use the 5 Hall leads of the brushless controller (60° or 120°) to connect the positive and negative power supply of the Hall element leads of the brushless motor, and connect the other three phase sensors A, B, and C to the leads of the Hall signal lead of the controller. Turn on the power of the controller, and the controller will supply power to the Hall element, and the phase angle of the brushless motor can be detected.
