DEVICE FOR CONTROL OF DOUBLE-FED MOTORS

摘要

FIELD: electrical engineering.SUBSTANCE: introduced into the device for control of a double-fed motor designed as based on an asynchronous motor with a phase-wound rotor, a parameter setting unit, a functional generator, a magnetic flux limiting unit, a magnetic flux setting commutator, an excitation frequency regulator, an excitation frequency sensor and the rotor phase voltages sensor that are connected to elements forming parts of the device as specified in the invention formula.EFFECT: implementation of a control law thanks whereto minimum losses across the whole of the range of loads are ensured in the electric drive.2 dwg
