DC Motor Commutator Features

1. To be free from void(bubble) more than 1mm and cracks in molded resin surface, but air hole(depth 1.6± 0.1, width 0.5± 0.05 ) should be tolerated.

2. Voltage Test: Bar to bar at 600V, 1s, and bar to shaft at 3750V, 1 min, there will be no break down or flash

3. Spin Test: Under 180±2 ℃ , 46800rpm, 10mins, the max change in OD is 0.01mm and the max deviation between bar to bar is 0.007.

4. Insulation Resistance: The insulation resistance is greater than 50MΩ under 500V.

Working principle of DC motor commutator

The segments of the motor commutator are usually made of copper and are separated from each other by mica insulation. The mica is cut so that it lies below the copper segments. Slots are cut in the riser on the commutator to facilitate the soldering of the ends of the coils. There are twice the number of segments on the commutator as there are slots in the laminated core for the coils.

On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor is energized in respect to the field coils. By mechanically positioning the brushes on the commutator, an angle of displacement can be set up between the magnetic force of the field windings and the magnetic force of the rotor windings.
