Commutator made of phosphor bronze

Update:10 May 2021

Usually factories use DC motors for daily energy supply, and DC motors generate energy through the interaction between the magnetic field of the rotating armature and the magnetic field of the fixed stator. And when the motor supplies energy, a device is needed to change the current supply mode, then we can use the motor commutator.

Usually the motor commutator is made of phosphor bronze, and the device is connected to the armature core, so that the current in the armature winding can be collected effectively. When the DC motor is working, the commutator will direct the applied DC voltage to a specific brush, and the brush will make the necessary contact with the commutator. And the voltage stored in the brush will switch the commutator piece, thereby changing the polarity of the coil in the commutator, and at the same time changing the coil can make the motor rotate in one direction, and will maintain the same polarity.

Because the motor commutator is made of better metal, it can effectively collect the current in the armature winding. Therefore, more and more factories begin to use this commutator for daily energy supply, and this commutator is well received by the industry.

Usually we use a motor commutator to control the reverse rotation of the coil in the electromagnetic field. When the contaminants in the commutator accumulate to a certain mass, the brushes in the commutator will be short-circuited, causing the motor to fail. normal work. Therefore, it is very important to clean the motor commutator in time.

We can use a contact cleaner to clean the commutator, usually we spray the contact cleaner on the commutator, and then use a toothbrush to clean the commutator carefully, so that we can remove the adhering to the commutator Other pollutants such as oil and dust.

Next, we need to clean the internal parts of the commutator. Usually the internal parts of the commutator are made of copper. We can also use contact cleaners to clean them. Because there is an insulating layer inside the commutator, we need to use an electronic contact cleaner to clean the inside of the commutator, so that it will not cause unnecessary trouble to the insulating layer in the commutator.
