1. It is strictly forbidden to wear gloves.
2. Before work, check whether the equipment and dust suction device are in good condition.
3. The commutator must be rolled firmly when getting on the vehicle, and hands must not be close to the groove.
4. The commutators should be stacked neatly and stably, and should not be too high.
5. Regularly clean the dust suction device to ensure effective dust suction. That's what 2 said. When the rotor rotates, the carbon brush does not move, and then the pair of contact pieces contacted each time are different, and then maintain it to continue to rotate. At the same time, when rotating, one group of windings can be energized in the forward direction, and the other group can be energized in the reverse direction to obtain higher efficiency and power output.
Each group of windings of the component has at least one pair of contact strips. If it is a multi winding motor, it is possible that multiple windings share one contact strip. There is a contact piece connected with the winding, and then there is a carbon brush on it. On the contrary, strengthening the maintenance of the collector department can find and solve problems as soon as possible, and many accidents can be avoided.
