The commutator mainly has specifications of hook type, groove type and flat type. Refined from imported raw materials, the product's performance has reached the international level to improve its predecessors. It is widely used in power tools, household appliances, automobiles, motorcycle motors and other fields; slip rings, carbon brush holders, and wiring boards have various specifications and models.
It is used in the fields of automobile generators, gasoline generators, etc. The commutator plays the role of rectification, and its role is to make the direction of the current in the armature winding alternating, so as to ensure that the direction of the electromagnetic torque is always the same.
In the generator, the commutator can make the alternating potential in the element into the DC potential between the brushes; in the electric idea, it can make the applied DC current into the AC current in the element, and generate a constant direction of torque.
Material characteristics
1. Chassis: cast with high rigidity FC-25 cast iron;
2. Gear: Made of high quality and high purity alloy steel 50CrMnT quenched and tempered, carburized and quenched and ground;
3. Spindle: High-quality and high-purity alloy steel 40Cr quenched and tempered, with high suspended load capacity. How the commutator works
4. Bearing: Equipped with roller bearing with heavy load capacity;
5. Oil seal: It adopts imported double-lip oil seal, which has extremely high dust and oil leakage resistance.
Operating procedures
1. Never wear gloves.
2. Before work, you must check whether the equipment and dust collection device are intact.
3. The commutator must be rolled firmly when getting on the car, and the hand must not approach the slotted part.
4. The commutators should be stacked neatly and smoothly, and should not be too high.
5. Clean the vacuuming device frequently to ensure effective vacuuming. That ’s what 2 said. The rotor rotates, and the carbon brush does not move. Then each time a pair of contact pieces are different, and then keep him going. At the same time, one group of windings is energized positively while the other group can. Reverse power for higher efficiency and power output.
