Wuxi Sine Power Science and Technology Co., Ltd. will introduce to you how to do when we encounter water ingress in the electric motor under general conditions.

Motor (commonly known as "motor") refers to a kind of electromagnetic equipment that converts or transmits electric energy according to the law of electromagnetic induction. In the circuit

It is indicated by the letter M. Its primary effect is to generate driving torque, as the power source of electrical appliances or various machines. The generator is indicated by the letter G at the top of the circuit. Its primary effect is to convert electrical energy into mechanical energy. The motor mainly consists of an electromagnet winding or distributed stator winding used to generate magnetic field, a rotating armature or rotor and other accessories. Under the effect of rotating magnetic field of stator winding, there is current passing through and receiving magnetic field effect in armature squirrel cage aluminum frame to make it rotate.

Brushed high-speed motor. This kind of motor has high efficiency, strong ability to climb with overload, and huge starting force. It can output power after decelerating through speed change gear equipment, and has noise. Brushless low-speed motor and gearless equipment have the advantages of no protection and no noise, but the controllers are messy, the starting current is large, and the overload climbing ability is poor. Brushed low-speed motor and gear equipment without reducer are simple in structure and low in cost. Only when starting and going uphill can overload be poor, and power consumption is large. Due to the high speed of the brush high-speed motor, it needs to output large torque power after decelerating through the reduction gear equipment, so its noise is relatively greater than that of the low-speed motor.

Connection method of electric motor, and phase angle judgment of brushless motor. The phase angle of the brushless motor is the abbreviation of the phase algebraic angle of the brushless motor, which refers to the angle at which the internal current direction of each coil of the brushless motor changes in a power cycle. The common phase algebraic angle of brushless motor for electric vehicle is 120 ° and 60 °. Wiring method of brush motor. Brushed motors generally have positive and negative leads. Generally speaking, the red line is the positive step of the motor and the black line is the negative step of the motor. If the positive and negative order AC wiring is used, it will only make the motor reverse, and generally will not damage the motor. What to do if the electric vehicle motor gets water? The electric vehicle motor is the core part of the electric vehicle. If it is damaged, it will cause the electric vehicle to fail to operate. Especially in rainy days, the electric vehicle cannot be pushed into the house, which will lead to water ingress into the electric vehicle motor. If the electric vehicle motor has water, it may burn the motor under high temperature operation, and then cause internal short circuit of the motor. In this case, you can put the electric vehicle aside for a few hours. If the electric vehicle can operate normally, it indicates that the electric vehicle motor is normal; In addition, you can also disassemble the electric vehicle motor and remove the moisture inside the motor. You can also go to the after-sales service department for testing and let professionals remove the moisture inside the motor.

The above is what Wuxi Sine Power Technology introduced to you.
