Abstract
A wheel slip correction system for an electric traction motor propelled vehicle having a plurality of DC electric traction motors with series connected armature and field windings incorporates an apparatus connected in circuit with each motor for reducing motor armature current in response to a motor speed increase caused by wheel slip. The apparatus is arranged to be non-power dissipative during non-wheel slip conditions.
Claims11
A wheel slip correction system for an electric traction motor propelled vehicle, the vehicle having a plurality of DC electric traction motors each having a series connected armature and field winding, the system comprising:
- a plurality of DC electric traction motors each coupled in driving relationship to at least one wheel of the vehicle;
- an electric power source connected for supplying electric power to the series connected armature and field winding of each of the motors;
- a plurality of armature current adjusting circuits, each of the circuits being connected in circuit with a respective one of the motors for reducing motor armature current, when actuated, of at least a motor coupled to a wheel detected to be slipping, the apparatus being arranged to be non-power dissipative during non-wheel slip conditions.
A wheel slip correction system for an electric traction motor propelled vehicle, the vehicle having a plurality of driven wheels, the system comprising:
- a plurality of DC electric traction motors each connected in driving relationship to at least one wheel of the vehicle;
- an electric power source for supplying DC electric power to each of an armature winding and a field winding of each motor;
- and
- apparatus connected in circuit with each armature winding and responsive to a wheel slip condition for reducing armature winding current in the motor coupled to the slipping wheel without increasing field winding current in such motor, the apparatus comprising a voltage source for inserting a reverse voltage in series with the armature winding and DC electric power source so as to reduce voltage applied to the armature winding.
