The reversal of the angle grinder is due to the polarity exchange of two wires in the armature winding of the motor, causing the motor to reverse. To adjust the angle grinder to forward rotation, it is necessary to change the connection method of the wires in the motor armature winding to restore normal polarity. The specific steps are as follows:
1. Remove the power cord of the angle grinder to ensure safety.
2. Open the casing of the angle grinder, locate the armature winding of the motor, and check the connection method of the wires.
3. If an error is found in the wire connection method, the order of wire connections needs to be changed. Specifically, connect the electrode cable to the opposite polarity terminal on the armature winding.
4. After completing the wire connection, turn on the power of the angle grinder again, start the motor, and check if it has returned to normal rotation.
If none of the above methods can solve the problem, it may be that the motor itself has malfunctioned and professional personnel need to be sought for repair or replacement of the motor. Be sure to pay attention to safety during operation to avoid accidents.
