The Electromagnetism Theory Of The Inter-feeding Cascade Control Motor

It is well-known that speed governor operation has more remarkable energy-saving effect for fans and water pumps. The inter-feeding motor is a new wound field motor, appeared in recent year. It mainly applied in fan and pump speed control, especially in high-voltage and high-capacity. It still has the advantage of saving in floor space, low cost and high rate. Otherwise,In wind power generation, it bring high profit than other motor. This paper analyses the electromagnetism theory of the inter-feeding motor and established the mathematical mode and the steady-state equivalent circuit base on the d-q-0 coordinate conversion of the doubly fed motor. Introduce the inter-feeding cascade control system based on the analyses of the problem of the tradition cascade control system. At last, it is emulated by S-function. See from the result of the simulation, it's proved the correctness of the electromagnetism theory of the inter-feeding motor.
