Use of electric motor

Anqing Dongqin Electronic Technology Co., Ltd. specializes in the production and development of camera autofocus motor, today Xiaobian to introduce the use of electric motors.

The typical induction motor is very widely used in a wide range of electric applications, from heavy industry to small toys. Different types of motors will be selected in different environments. Here are some examples: Air equipment, such as electric fans, electric toy cars, boats and other lifts, elevators, means of transport driven by electricity, such as underground railways, trams, transport belts in factories and hypermarkets, electric automatic doors on buses, electric rolling gates, livelihood products optical drives, printers, washing machines, water pumps, disk drives, electric razors, tape recorders, video recorders, etc. CD turntable industrial and commercial uses for fast elevator, working mother machine textile machine, blender.

The principle of motor and generator is basically the same, and the direction of energy conversion is different respectively. The generator converts mechanical energy and kinetic energy into electric energy by means of load (such as hydraulic power and wind power). If there is no load, the generator will not have current outflow. The combination of motor and power electronics and microcontroller has formed a new science, called motor control. Before using the motor, it is necessary to know whether the power supply is DC or AC. If it is AC, it is also necessary to know whether it is three-phase or single-phase AC. The wrong power supply will lead to unnecessary loss and danger. If the motor is not connected to the load or the load is very light so that the motor speed is fast, the induced electromotive force is strong, and the voltage at both ends of the motor is, the voltage provided by the power supply minus the induced voltage, so the current is weakened. If the load of the motor is very heavy and the speed is slow, the induced electromotive force is relatively small. Therefore, the power supply needs to provide a larger current (power) to output the work with the required higher power.
