What is the motor?
A motor is a rotary electric machine that converts electrical energy into mechanical energy, which mainly includes an electromagnet winding or a distributed stator winding and a rotating armature or rotor for generating a magnetic field. Under the action of the rotating magnetic field of the stator winding, it has a current in the armature squirrel cage aluminum frame and is rotated by the action of the magnetic field.
Generally refers to the DC brush motor, the benefits of the control speed is relatively simple, as long as the control voltage size has been able to control the total speed, but such motors should not be in high temperature, flammable and other environments, and because the motor needs to carbon Brush as part of the commutator (brush motor), so the need to regularly clean the carbon brush friction caused by dirt. At the same time, there are DC brushless motor, is a synchronous motor, relative to the brush, brushless motor because less carbon brush and shaft friction so more power is also relatively quiet, but the price is higher, but also need to add no additional Brush controller.
It can be in high temperature, flammable and other environments, and do not have to clean the carbon brush, but in the control speed is more difficult, because the control of AC motor speed there are two ways: one is to use the inverter to control the frequency of alternating current, another Kind is the use of induction motor, with increased internal resistance of the way, at the same frequency of alternating current to reduce the motor speed, control the voltage will only affect the motor torque. General household motor voltage 110V and 220V, etc., in industrial applications, there are 380V or 440V and other types.
Features of Motor
1, the conductive conductor in the magnetic field will be the role of force. Its force direction with the current direction, the direction of the magnetic induction.
2, the motor consists of two parts of the rotor and stator. The part that can be rotated is called the rotor; the fixed part is called the stator.
3, when the DC motor coil to the equilibrium position, the coil will no longer turn, only to change the direction of the current coil, the coil can continue to turn down. This function is achieved by commutator. The commutator is made of a pair of semicircular iron pieces which change the direction of the current in the equilibrium position by contact with the brush. The actual life of the motor brush has a lot of pairs, and will use electromagnetic fields to produce strong magnetic field.
4, the motor structure is simple, easy to control, small size, high efficiency, power can be large or small, is widely used in daily life and various industries. It is represented by M in the circuit diagram. When the motor is working, it converts electrical energy into mechanical energy.
