ABSTRACT:
A control system is provided which is particularly suited for employment for purposes of effecting control over the electric motor embodied in an electrically powered motor vehicle which is operable therein as the prime mover thereof. The control system of the present invention is capable of being utilized with all types of electric motors including direct current permanent magnet motors, direct current series wound motors, direct current series shunt motors, or any possible magnet and winding combination of direct current motor. Moreover, the control system of the present invention is further applicable for use with electrically powered motor vehicles that employ alternating current motors of any type such as for instance mutual induction and excited rotor motors. The control system includes a linear field control motor which has two main moving segments. The first of these comprises the armature or rotor which is the element that revolves and which in accord with conventional practice provides the mechanical force output from the motor. The other segment of the linear field control motor is the field or the stator which is movable linearly relative to the armature or rotor. More specifically, the armature or rotor of the linear field control motor can be referred to as the revolving field (RF) segment of the motor, i.e., the mechanical revolving field that is attached to the output shaft of the motor, while the field or stator of the linear field control motor is referred to as the linear field (LF) segment of the motor, i.e., the nonmechanical revolving field of the motor. The linear field segment includes a housing operable to hold the permanent magnets for field winding segments or the field windings. The linear field segment moves linear to the revolving field segment on support tracks, provided for this purpose, utilizing any one of various forms of linear bearings. The revolving field member is the common revolving member, but does not move in a linear relationship relative to the ends of the motor. The revolving field segments can be constructed so as to embody various forms of mechanically revolving fields.
