In many appliances and tools production processes, each product requires a motor, but the time of using the product is short, resulting in a waste of resources. The motor is used as the core of a series of home appliances and power tools. The design of the motor can be quickly installed in different modules to reduce the number of motors needed for home appliances. It allows users to obtain different modules and install the motor core in various home appliance modules when required. It effectively solves the problem of overproduction to avoid waste.
