1. Maintenance method for motor Hall sensor

A. Visually inspect whether the wire color of each plug is connected correctly, and whether the plug blades and springs of the connectors are reliably connected. To avoid misconnection or poor contact that may prevent normal operation.

B. Hall detection method

1. Multimeter testing method

a) Measure the voltage between the Hall power supply (red and black lines) using a multimeter voltage range (20V DC) to see if there is 4.3V.

b) Observe the working voltage of the Hall signal lines (yellow, green, and blue) to ground using a multimeter voltage range (20V DC). Slowly reverse the motor and observe whether the voltage of each signal line varies between 0V-4.3V. If a certain phase does not change, it indicates that the Hall effect of this phase is broken.

2. Hall inspection method

Connect the Hall connector of the Hall detector to the motor and connect the power supply. Slowly reverse the motor and observe whether the LEDs corresponding to each signal line are flashing. If a certain phase does not change, it indicates that the Hall effect of this phase is broken.

Motor Hall maintenance method
A. Tespect whether the wire color connection of each plug is correct, and whether the insert and spring of the connector are connected to each other. In order to avoid incorrect connection or poor contact and unable to work normally.
B. Hall detection method 1. The mutmeter detection method A uses the mutmeter voltage gear (DC 20V) to measure whether the voltage between the Hall power supply (red and black lines) is 4.3V.
B) Use the meldometer voltage gear (DC 20V) to observe the working voltage of the Hall signal line (yellow, green and blue) to the ground respectively. Slowly reverse the motor to observe whether the voltage of each signal line changes between 0V---4.3V. If a phase does not change, it means that the phase Hall is broken.
2. Hall maintenance method The Hall connector of the Hall detector is docked with the motor, and the power is turned on. Slowly reverse the motor to observe whether the LED corresponding to each signal line flashes. If a phase does not change, it means that the phase Hall is broken.
Controller maintenance method
A. When the wire is not connected, the resistance between the three phase lines should be measured with a universal resistance gear (200K) when the controller is not connected to any plug. Normally, it should be greater than 18K. If it is less than 18K, it can basically be determined that the power tube is burned out.
B. The spective measurement is mainly to detect whether the wire color connection of each plug is correct before powering on. In order to avoid connection errors and the phenomenon of burning the controller
C. The maltimeter measurement after the actual car is powered on
1 Phenomenon: Turn, the motor does not turn
Maintenance process: (60V motor is a column)
A) Use the maltimeter voltage gear (DC 200V), for the 60V battery, measure whether the power cable and door lock wire are 60V. If there is no 60V, check whether the vehicle power cable is in normal contact. The voltage of other specifications of the power supply is consistent with the voltage of the battery pack. B) Detect the brake circuit to see if it is in the braking state (the tail car will light up when braking). You can use a meter to check whether the brake level has changed. C) To check whether the motor hall is normal, you can refer to the motor hall detection method. D Use the meltmeter voltage gear (DC 20V) to measure whether the voltage between the handle power supply (red and black lines) is 4.3V. If there is no 4.3V, it means that there is a problem with the internal power supply of the controller. E) Use the molter voltage gear (DC 20V) to measure the rotor signal line (green) to ground (black) voltage (measured on the controller output line). In the case of turning the handle, this voltage should change linearly between 0.8-42V as normal. If the voltage remains unchanged, you can replace a turnbar and try again. If the fault can't be solved, replace the controller.
2 Phenomenon: Always running in low-speed gear, unable to change to high-speed gear maintenance process:
A) Check whether the low-speed locking line is short-circuited between the gray line and the black line. When short-circuited, it is locked at low speed. This connector can be unplugged. Let's see if it can be converted normally. B) Use the mallmeter voltage gear (DC 20V) to measure whether the battery voltage is lower than the undervoltage value of the battery under load. If the battery voltage is too low, it may not be converted. This is a normal phenomenon, mainly to protect the battery from being damaged when it is discharged when undervoltage. It is recommended to re-verify with a fully charged battery.
