Claims

[Scope of utility model registration request]

(1) A rotor consisting of magnetic poles provided on a rotating shaft, a slip ring, and a field coil wound around the magnetic poles, which slides into contact with the slip rings in order to magnetize the magnetic poles of the rotor, A vehicular generator comprising a brush for feeding power to a field coil, characterized in that the brush is coated with a conductive abrasive.

(2) A generator for a vehicle according to claim 1, which is characterized in that the entire brush is uniformly mixed with an abrasive.

(3) A generator for a vehicle according to claim 1, which is characterized in that an abrasive is disposed at the tip of the brush.

(4) Utility model registration claim 1, characterized in that abrasives are arranged in layers in the horizontal direction at the tip and middle of the brush.
Generators for vehicles as described in section.

(5) A generator for a vehicle according to claim 1, which is a utility model registration, characterized in that an abrasive is arranged in a layer in the vertical direction in the middle of the brush.
