What is the main function of an electric motor?

Author:

Electric machine (commonly known as "motor") refers to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. The function of an electric motor is to convert the electrical energy of the battery into mechanical energy, driving the wheels of the electric vehicle to rotate, in order to achieve the goal of continuous cycling of the electric vehicle. When the motor is working, the coil and commutator rotate, while the magnetic steel and carbon brush do not rotate. The alternating changes in the current direction of the coil are completed by the commutator and carbon brush that rotate with the motor. A brush motor has a greater force than a brushless motor, with fewer wires, just one positive and negative wire and one negative wire. If the motor rotates in reverse, it can be completed by simply adjusting the positions of the two wires. In the electric vehicle industry, brush motors are divided into high-speed brush motors and low-speed brush motors. There are many differences between brush motors and brushless motors, and a simple way to distinguish them is: brush motors have carbon brushes, while brushless motors do not have carbon brushes. But the noise of the brush motor is relatively high, and currently the brush motor has been basically eliminated. Common types of motors include: brush toothed high-speed hub motors, brush toothed low-speed hub motors, brush toothed low-speed hub motors, brush toothed high-speed hub motors, side mounted motors, etc.

The commonly used materials for motors include conductor materials, insulation materials, thin films, adhesive tape composite materials, and organic materials. 1. Conductor material: Copper, aluminum, copper aluminum alloys, silver, etc. Due to the high cost of silver, it is not used in large projects.

The common power of motors is: three-phase 222 motor, with a kilowatt of 3.5 amperes. Commonly used are 38 motors, one kilowatt and two amperes. Low voltage 660 motor, kilowatt 1.2 amperes. High voltage three kilovolt motor, four kilowatts per ampere. High voltage six kilovolt motor, eight kilowatts per ampere. Electric machine (commonly known as "motor") refers to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Represented by the letter M in the circuit (old standard used D). Its main function is to generate driving torque as a power source for electrical appliances or various machinery. The generator is represented by the letter G in the circuit. Its main function is to convert mechanical energy into electrical energy. Currently, the commonly used method is to use thermal energy, water energy, etc. to drive the generator rotor to generate electricity. Power is a physical quantity that characterizes the speed of work done. The work done per unit time is called power, expressed in P. Therefore, power is equal to the scalar product of the applied force and the velocity at the point of force on the object. It refers to the work done by an object in a unit of time, that is, power is a physical quantity that represents the speed of work done. Power can be divided into electrical power, force power, etc. Therefore, the calculation formulas are also different. Electric power calculation formula: P=W/t=UI. According to Ohm's law, U=IR can be substituted into P=UI to get: P=I * IR=(U * U)/R

A machine that converts electrical energy into mechanical energy. 1) DC motor - A motor that uses DC current to rotate is called a DC motor. Due to the different ways in which the magnetic field circuit is connected to the armature circuit, it can also be divided into series excited motors, split excited motors, and compound excited motors; (2) AC motor - An electric motor that uses AC current to rotate is called an AC motor. There are many types, mainly including
