Electric motor lock, with what method can you fix it
Terms of settlement：The main motor and the control motor are two sets of circuit power supply, the two motor can not share the power supply, also cannot connect directly. The control motor is energized so as to slow or stop the main motor, and of course to the main motor. With regard to this problem, it is possible to control the logic level of the motor and reverse the level at which the normal operation is taken as the level of the control motor. The circuit of the control part needs to be carefully checked.
Electric bikes in the ramp up driving motor suddenly locked, unable to walk, turn the handle wheel cannot rotate, and the power indicator does not change. When the power is switched off, the resistance is greater when driving, and accompanied by a strong vibration. The initial judgement is that the bearing damage or motor damage. After the motor wheel is removed, the insulation skin of the line joint is burnt out, and the three power wires are connected together. After the power line is separated, the motor is turned and flexible. The analysis results for the motor, grew up in the load line overheating insulation coking after short circuit, motor and generator and motor are interchangeable, after a short circuit into a generator, and the line and the short circuit so wheel motion is produced when larger magnetic field and vibration resistance.Electric motor is generally brushless motor, generally not easy to burn, after the failure of the first check whether the circuit is good.
When the external force turns the motor, it turns into a generator, and the line short circuit causes the electric energy generated to produce the magnetic field in the motor coil, which results in the mutual control of the permanent magnetism in the motor.
