1. Field of the Invention
The present invention relates to permanent magnet DC motors and, more particularly, to electric motors which provide new and improved operation with simultaneous battery regenerating without interfering with the operation of the motor driving system.
2 . Description of the Related Art
Exemplary type permanent magnet and direct current motor systems are disclosed in U.S. Pat. Nos. 5,117,141; 4,371,801; 4,358,693; 4,237,410; 4,169,983; 3,996,504; 3,633,084; 3,418,506; and 3,334,254.
Electrical battery systems known in the art suffer from various drawbacks which prevent such systems from achieving maximum performance and reliability. Such problems include a lack of simultaneously charging a long lasting battery energy supply during operation of an electrical battery system. It would, therefore, represent an advance in the art to provide a new improved simultaneous direct current charging system which acts to charge the batteries of a vehicle such as an electric car without having to stop the vehicle.
