Whether brushless motor or brushless motor, it is normal to produce some mechanical noise (brushless) or electric magnetic resonance (EMR) during operation. However, if the brushless motor produces abnormal vibration and sound during operation, the power lock should be shut off and overhauled in time.
When the electric dirt bike moves backwards, it is normal to feel the rear wheel regress heavier, which is a normal phenomenon. When the electric vehicle is moving forward, when the resistance is high, the motor power supply is disconnected first (the forward resistance can be eliminated, and then the repair is carried out in time.
During normal use of the motor, special maintenance is not required normally, and attention shall be paid to checking the fastening state of the shaft end of the motor hub and the end cover of the motor, and if any screw or nut loosening phenomenon is found to be tightened in time, the failure of the vehicle due to disconnection of the lead – out wire is prevented, and the use safety is affected.
When driving on wet days, the depth of water should not exceed the bottom edge of electric wheel hub, so as to avoid motor fault caused by water seepage of motor.
