Current-type vector control of induction motor
专利汇可以提供Current-type vector control of induction motor专利检索，专利查询，专利分析的服务。并且PURPOSE: To accomplish correct constant-output control and to control a large-capacity system with a small capacity by setting effective magnetic fluxes, rotation speeds, or output torque and controlling vectors in search for the primary current and actual varible quantities.
CONSTITUTION: An effective magnetic flux standard and a roration standard are given by adjusting resistors 70 and 71. The input to a speed-control amplifier 72 is a difference between the rataion standard from the resistor 71 and the signal which is the result of sensing the output of a tachometer generator 65 by a speed senser 79. The signal ϕ from the resistor 70 and the output T from the amplifier 72 are input to a circuit 73, where the secondary interlinking magnetic flux ϕ
2 and a slippage frequency SW
e are produced. A circuit 74 receives ϕ
2 , SW
e and the output W
r from the speed sensor 79 and calculates the primary current i and the primary frequency W
e . The difference between the resultant primary signal and the signal from a current transformer 61 is input to the primary-current control amplifier 68, and the difference between the primary frequency signal and the frequency signal from a sensor 78 is input to a frequency control amplifier 75. In this constitution, correct and constant-output control can be accomplished.
