Synchronizing Properties of Impulse-Current Controlled Electric Drive of Coordinated Rotation in the Circuit of Electrically Coupled Rectifiers of the Rotor

摘要

Analytical dependences the equalizing current and the rotor slip differences vs the electric drive parameters are obtained. We established that the rotational speeds mismatch in the circuit to be considered is 2-2.5 times less than in the case the motors are operated in compliance with their natural characteristics. The drive electromechanical time constant increases by the same amount that significantly affects in the mismatch decrease under high-frequency disturbances. The denoted property also takes place in electric drives in the presence of elastic bonds.
