Motor maintenance of electric passenger tricycle
At present, there are three kinds of electric vehicle motors: brush speed motor vehicle, brushless low-speed electric vehicle motor and brush low speed electric motor. What kind of motor is not in use, and overload operation shortens its service life.
Whether it is a brushless electric vehicle or brushless electric motor, the input current will affect its performance. The voltage of the motor is supplied by the controller. The aging of the electronic components in the controller causes the current of the input motor to become larger. Therefore, it is necessary to check the controller and replace the controller if necessary. Periodically lubricate the electric motors, gears, bearings, and deceleration parts. If the gears and bearings are too worn out, the anti vibration piece is deformed, the spring performance degrades or breaks, all the controllers should be replaced. Pay attention to charge the battery of the electric vehicle frequently, keep the battery enough voltage, prevent the motor from heating due to the voltage shortage, and accelerate the aging of the electric motor.
Brush high speed electric vehicle, motor work at high current, brush and reduction gear wear faster. Brush low speed electric vehicle motor at high current iron loss is higher, DC power consumption becomes larger, long ride will cause motor heating, demagnetization of magnet steel, reduce efficiency, shorten service life. Therefore, the brush motor maintenance, should be the focus of the brush. Brushless low-speed electric vehicle motor, although there is no brush, but it needs Holzer reversing device. In the overload state, it is easy to reverse the problem, forming a magnetic short circuit, thus burning out the controller and Holzer components, so the overload has a great impact on brushless motor. The motor is the power mechanism of the electric vehicle, and its performance is good, which has a direct impact on the performance of the electric vehicle. Maintenance and maintenance must be maintained. Detect the degree of wear of electric bicycle brush and commutator. General brush wear to the distance from 4 to 5mm lead wire should be replaced, the commutator surface depth is greater than 0.5mm, should be replaced. For normal use motors, regardless of the degree of wear, they should be replaced on a regular basis (usually two years) with an electric brush and commutator.
