What are the types of AC asynchronous motors?
There are two types of AC asynchronous motors: generally, the wound-type asynchronous motors used in factories with relatively large starting loads have slip rings on them, so electric (carbon) brushes (such as lifting, rolling steel motors, etc.) are used, and squirrel cages are used for light-load starting. Type induction motors do not have slip rings, so they do not need electric (carbon) brushes (such as electric fans, washing machines, air conditioners, refrigerators, etc.). DC motors have commutators, so electric (carbon) brushes are used. Hand drills are generally DC motors. The bench drill is an AC asynchronous induction motor; although the general toys and electric shavers are DC motors, due to the simple structure, in order to reduce the cost, a phosphorus-containing elastic brass sheet is used to replace the electric (carbon) brush replacement. The direction device is the wearing part of the electric shaver (the wire package inside the motor is generally not damaged).
What are the characteristics of the commutator?
A magnetic signal converter (composed of a permanent magnet, a dry reed switch, and a transfer switch) is used to precisely control the commutation timing, and all parts that come into contact with the medium are made of stainless materials.
What does the commutator do?
Generally speaking, DC motors only have commutators.
The commutator is an important part of the DC motor. Its function is to convert the DC current passing through the brush into the alternating current in the winding or convert the alternating electromotive force in the winding to the DC electromotive force on the brush end.
In addition, it should be understood that the structure of the motor commutator is a part of the DC permanent magnet series excitation motor in order to allow the motor to continue to roll.
An important part of the DC motor, its function is to convert the DC current passing through the brush into the alternating current in the winding or convert the alternating electromotive force in the winding to the DC electromotive force on the brush end. It is suitable for engraving under the armature commutator slot of automobile motor, motorcycle starter motor, electric tool motor and micro motor. Put an armature into the positioning seat, the start switch will be automatically tightened, and the machine will automatically find the slot, Next engraving and indexing, until the next engraving is completed and the top tightening device is automatically released. Then, the operator removes the armature and puts another armature in the positioning seat, and starts the cycle again. Features The commutator is a DC permanent magnet A part of the serial excitation motor in order to allow the motor to continue to roll.
