Today, Wuxi Sine Power Technology introduces to you how to solve the problem of electric motor encountering water

This kind of electric motor consists of stator magnetic step, rotor, brush, shell, etc. The stator magnetic step is made of permanent magnet, including ferrite, aluminum nickel cobalt and other materials, and can be divided into cylinder type and pad type according to its structure; The rotor is generally made of silicon steel sheets by lamination. The enamelled wire is wound between two grooves of the rotor core, and each joint is welded to the metal sheet of the commutator; The electric brush is a conductive part connecting the power supply and the rotor winding, with both conductive and wear-resistant properties. At present, this form is widely used for electric motors. Brushed high-speed motor. This kind of motor has high efficiency, strong ability to climb with overload, and huge power. It can output power after decelerating through speed change gear equipment, making noise. Brushless low-speed motor. No reduction gear equipment has the advantages of maintenance free and noise free, but the controller is messy, the starting current is large, and the overload climbing is poor. Brushed low-speed motor. The gear equipment without reducer has simple structure, low cost, poor starting and uphill overload, and large power consumption.

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. Phase angle discrimination 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 view point where the current direction inside 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 °. What should we do if the electric vehicle motor is flooded? The electric vehicle motor is the core part of the electric vehicle. If it is damaged, it will cause the electric vehicle to be unable 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 form an 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 is necessary to clarify 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. Brushless DC motor is composed of permanent magnet rotor, multi-stage winding stator, azimuth sensor, etc. It has the advantages of high reliability, no commutation spark, low mechanical noise, etc. The characteristic of brushless DC motor is brushless, which uses semiconductor switch equipment to realize electronic commutation, that is, electronic switch equipment replaces the traditional contact commutator and brush; The orientation sensor can change the current of stator winding along a certain order according to the change of rotor orientation. High speed permanent magnet brushless motor is composed of stator core, magnetic steel rotor, sun wheel, reduction clutch, etc. The cover of this kind of electric motor can also be equipped with a Hall sensor for speed measurement. There are three types of orientation sensors for electric motors: magnetic sensitive, photoelectric and electromagnetic.
