Micromotor company introduces the working principle of carbon brush motor
Release time:
2020-04-14
The working principle of 1. carbon brush motor The coil is connected to a commutator, and the commutator is fixed on the rotating shaft and rotates together with the motor shaft. The commutator and the commutator and the rotating shaft are insulated from each other. They are all called commutators. The brushes A and B are fixed in the space. A DC voltage is applied to the two brush terminals of the motor. Due to the action of the brush and the commutator, electric energy is introduced into the armature coil, and the coil side current under the same pole is always in the same direction.

The difference between carbon brush motor and brushless motor
Release time:
2020-04-15
1. Difference in scope of application: Brushless motor: It is usually used in equipment with relatively high control requirements and relatively high speed, such as aircraft models, precision instruments and meters, etc., which have strict motor speed control and high speed. Carbon brush motors: Usually power equipment uses brushed motors, such as hair dryers, factory motors, household range hoods, etc. In addition, the speed of series motors can reach very high, but due to the wear of carbon brushes, The service life is not as good as that of brushless motors.

Application of Micromotor in Automobile
Release time:
2020-04-16
Micro motors or simply micro motors are used in automobiles. Its function is to convert electrical energy into mechanical energy, thereby driving the equipment to run and starting the car. Generally speaking, in addition to the starter that starts the engine, the electric motor of other components is also a micromotor, so it has become an indispensable component in the car and is the source of power for other components. The micromotors in the car are all miniaturized DC motors, and their total power is under 100 watts. Due to the particularity of automobile operation and the bad environment, the requirements for automobile micro-motors are getting higher and higher, and the quality is getting better and better. Determine the mass of the motor. In addition to the design structure and processing technology, it also includes the magnetic material of the movement.
