Abstract
An electrical machine which has a rotor positioned within a housing. The rotor has a pair of spaced-apart engagement portions, which, preferably, are tapered. The engagement portions are engaged by collectors or brushes which are arranged in annular configuration around the engagement portions. Retainer support the collectors and serve as electrical conductors with respect to the collectors. Wick elements engage the tapered portions of the rotor adjacent the collectors and provide lubrication and coolant fluid to the collectors and to the surfaces of the engagement portions of the rotor. Actuator mechanisms continuously urge the retainer members and the collectors in an axial direction upon the engagement portions to automatically compensate for wearing action between the collectors and the engagement portions of the rotor. A stator encompasses the rotor to create a magnetic field which encompasses the rotor.
