The expansion machine is popular with many customers nowadays. Why? Because this machine has complete functions and can complete the work that we cannot complete manually, so this expansion machine is more popular. So do we know what the main components of this machine are? It is the motor. What if the motor of the automatic expansion machine is broken? First of all, let's look at what a motor is.
In daily life such as industrial production, many machines and equipment are used by our customers, such as air machines, lathes, grinders, etc. The prime mover that drives these production machines to operate is generally an electric motor.
The whole composed of electric motors, control devices, transmission devices, production machinery and power supplies is called an electric traction system or production machinery system.
1. The motor is the prime mover of electric traction. It is a component that converts electrical energy into mechanical energy. By controlling the motor, the required torque, direction and speed can be obtained.
2. The control device is a device that controls the operation of the motor. It is composed of various control electrical appliances, such as switches, buttons, fuses, contactors and relays. They are connected according to certain processing technology or movement requirements and rules. It is used to control the start, stop, brake and speed regulation of the motor. In order to ensure that the electric traction control system works well and reliably, low-voltage electrical appliances must be correctly selected and used according to the technical requirements of the control circuit. Improper selection or use will lead to various faults, and even damage electrical equipment in serious cases. For this reason, it is required to master the selection and use of low-voltage control electrical appliances.
Control devices can be divided into two categories: manual and automatic. Manual control devices are operated by staff, such as knife switches, combination switches, etc.; automatic control devices automatically operate according to instructions, signals or changes in certain physical quantities (time, speed, temperature, etc.), such as relays, contactors, travel switches, etc.
3. The transmission device is an energy transmission machine between the motor and the production machinery, which connects the motor and the production machinery into one. The types of transmission devices mainly include gear reducers, worm gear reducers, pulleys, couplings, etc. Different production machinery has different requirements for transmission devices. Choosing a suitable transmission device can make the production machinery reach an ideal working state.
