One of the core components of electric vehicles, the motor, is composed of the stator, rotor, and end cover. The operation and performance of the motor are closely related to the cleanliness of the stator and rotor. The presence of a large amount of dust and other dirt on the surface of the stator and rotor can reduce the performance and lifespan of the motor, and even cause short circuits or burns, which can have a certain impact on safe driving. Therefore, new energy vehicles require regular cleaning of the stator and rotor.

In response to the problems existing in the cleaning process of stator and rotor of new energy vehicles, Suzhou Guchi Intelligent combined the application of stator and rotor cleaning processes from multiple customers and market research data to compare and analyze the cleaning plans of stator and rotor from aspects such as equipment selection and cleaning plans, in order to provide more competitive stator and rotor cleaning plans, and ultimately formed a stator and rotor cleaning plan:

I. Equipment selection

1. It can achieve automatic feeding, automatic cleaning, and automatic transmission of the cleaned workpiece to the next workstation, achieving a fully automated cleaning process;
2. During the cleaning process, there is no human operation and no need for manual secondary handling, reducing labor costs. At the same time, it can achieve automatic discharge to meet the requirements of production rhythm;
3. Can achieve cleaning between stators and rotors of different lengths;
4. The equipment can achieve various forms of workpiece conveying, such as track conveying, roller conveying, lifting conveying, etc. The most suitable conveying method is selected according to the actual situation;
5. The equipment has a dust removal function, effectively removing dust from the surface of the stator and rotor.

II. Device Configuration

1. It can achieve the cleaning of stator and rotor, while meeting different process requirements.
2. Equipped with a professional dust removal system, it can remove dust from the cleaned stator and rotor during the cleaning process, achieving the effect of removing dust from the surface of the stator and rotor.
3. Configure an automatic circulating conveying system to achieve continuous cleaning of the stator and rotor.

4. Equipped with an automatic lifting platform, it can achieve cleaning from the end of the stator to the end of the rotor;

Ⅲ.Equipment cleaning plan

Suzhou Guchi Intelligent Stator and Rotor Cleaning Equipment, including automatic feeding device and automatic cleaning device. The automatic feeding device has two channels, upper and lower, and is driven pneumatically.

Ⅳ.Operation process

1. Loading and unloading, placing the stator and rotor on the conveyor line of the stator and rotor cleaning equipment through a robotic arm or conveyor belt;
2. Static electricity elimination: After the stator and rotor are pushed into the stator and rotor cleaning equipment, static electricity is first eliminated to prevent excessive electrostatic adsorption and unclean floating and sinking cleaning;
3. Dust raising module: After eliminating static electricity, the dust raising module first raises the floating dust;
4. Dust extraction module, which blows and sucks away the raised floating dust;
5. Signal detection, which detects the normal operation of each signal through monitoring.

V. Operating cost analysis

Compared with traditional stator and rotor cleaning methods, using a stator and rotor cleaning system can save a total of approximately RMB 100000 in labor costs, consumables costs, and water treatment costs annually. Without reducing product quality, it significantly reduces the operating costs of stator and rotor cleaning and maintenance, effectively improving customer satisfaction. Professional stator and rotor cleaning equipment is required. Please consult Suzhou Guchi Intelligent for more details.
