ABSTRACT:
A plurality of permanent magnet DC motors are grouped into two banks. One side of each motor in one bank is connected to a first common supply conductor while one side of each motor in the other bank is connected to a second common supply conductor. Independently operable switches are provided for connecting the other sides of respective ones of the motors in the first and second banks to a third common supply conductor. Three additional power switches are provided for reversibly connecting a source of potential across either bank of motors. By proper switch selection one or more motors in either of the banks may be operated in a selected direction of rotation.
