Parallel and differential operating mode for commutator motors with circular current suppression function

摘要

The present commutator type motor differential parallel operating circuit with imbalance current circulatory choke function relates to provide two or more series motor or compound motors with series winding or permanent-magnet type or shunt winding excitation type motor, and armature windings are respectively series with choke diodes along the positive direction of current, and each end of the choke diodes is parallel each other after parallel connected to limit resistor, and further series with respective series windings or series connected to the parallel series windings whereby series winding multiple motors parallel running has the characteristics of imbalance current circulatory choke function subject to load difference, and has some improvement for operative characteristics of the original series or parallel means as a result of reduction in circulatory flow between the armatures or distribution torque or regeneration power braking; or two or more permanent-magnet type or shunt winding type motors, and armature windings parallel connected each other after respectively series with anti-circulatory diodes or series connected to the limit resistors for restraining circulatory flow, or the anti-circulatory diodes are parallel connected to the limit resistors for giving regulation function for torque distribution between/among the motors and giving restraining function for current at the moment of regeneration power braking, or the aforesaid series limit resistors and choke diodes and resistors parallel connected to the choke diodes are jointly used.
