Doubly fed induction motors control in positional electrical drives

[摘要] The article discusses the phase control of doubly fed induction motors for positional electric drives and an assessment of their capabilities. The advantage of all variants of such control is the possibility of fixing the rotor position even in open systems when the windings are powered with nominal voltages and high smoothness of movement at very low speeds. The proposed methods for implementing the phase control of the doubly fed induction motors open up wide possibilities for solving specific problems of developing positional electric drives, providing high dynamic, accuracy and weight and dimensions rates.
