Commutator manufacturers introduce what is a commutator

An important part of the armature of a DC motor and an AC commutated motor, it plays a commutation role when the motor rotates. It is a component of a DC motor and an AC series motor as a current commutator, so that the motor continues to rotate, commonly known as a commutator.

The commutator manufacturer introduces the material properties of the commutator

1. Chassis: high rigidity FC-25 cast iron;

2. Gear: made of high-purity alloy steel 50CrMnT quenched and tempered, carburized, quenched and tempered, and ground;

3. The main shaft is processed by a high-purity alloy steel 40Cr quenching and tempering technology, which has the ability of high suspension and heavy load problems in China;

4. Bearing: equipped with roller bearing with heavy load capacity;

5. Oil seal: It adopts imported double-lip oil seal, which has high dust-proof and anti-leakage ability.

The commutator manufacturer introduces what is the function of the commutator

The commutator structure mainly includes hook type, groove type, plane type and other different specifications. Refined from imported raw materials, the product performance has reached the international advanced level, and is widely used in electric tools, household appliances, automobiles, motorcycle motors and other fields; collector rings, carbon brush holders, and wiring boards have various specifications and models.

Used in Chinese automobiles as generators, gasoline generators and other fields. The commutator plays a rectifying role, and its role is to make the current in the armature winding develop and alternately change, so as to ensure that the direction of the electromagnetic torque of the system remains unchanged.

In the generator, the commutator can make the AC working potential in the system components change into the DC potential between the brushes; in the motor, it can make the DC current we add into the AC power in the electronic components, producing a Constant horizontal torque.

The commutator manufacturer introduces what is the role of the commutator in the DC motor

1) The commutator acts as a ballast, and the alternating current in the electrical control winding is rectified into direct current, which is output at both ends of the positive and negative brushes at the same time.

2) The commutators play the role of inversion, that is, the direct current in the external circuit of the brush can be inverted to use the alternating current through the electronic commutator, and output to an electric lead-out element.

The commutator manufacturer introduces the role of the commutator in the electric vehicle motor

We can see it on the electric car motor, its rotor is equipped with a conductive ring composed of many copper sheets. It is connected to an external power source via a pair of brushes. We call it a commutator, and it plays a role in an electric vehicle motor.

1. The electric current of the electric vehicle motor is equal and opposite before and after the commutation.

2. The commutation of the motor of the electric new energy vehicle is to convert the current induced in the armature control winding into alternating current. Through the mechanical design of the point brush and the commutator, the current flowing into the external circuit is direct current.

3. The commutation of the motor in electric vehicles can reduce sparks by improving the working environment conditions of the commutator.

4. The floating pre-drive circuits of the electric vehicle motor are independent of each other and powered by an independent power supply. So when they are commutated, our EV motors make separate control signals and their respective pre-drives.

The surface of the electric vehicle motor should be smooth, but there should be a dark brown cuprous oxide protective layer, which can increase the contact resistance between the brush and the commutator, reduce the short-circuit current under the brush, and play a protective role in replacement.
