Title: Computing method for position of magnetic flux of induction motor, and its control method using the same
Inventor: OKUYAMA TOSHIAKI
IPC: H02P23/16
Filed: 1993-04-28
Abstract: PURPOSE:To perform a highly accurate speed-control of an induction motor inclusively of the region adjacent to zero-speed, by superimposing on the driving voltage of the motor an AC voltage having a different frequency from its frequency, and by measuring an inductance of the motor based on the current of the motor and the AC voltage, and further, by computing the position of the magnetic flux of the motor based on the inductance. CONSTITUTION:On the command value of the output voltage of an inverter 1, a sine wave AC voltage is superimposed, and the components of the current of a motor 2 which flows responding to the sine wave AC voltage through the winding of the motor 2 are sensed respectively, and further, from the AC voltage and the current the leakage inductance of the winding of the motor 2 is measured. Then, based on the phenomenon wherein the leakage inductance is varied by the positional relation between the winding and the magnetic flux of the motor 2, the position (rotational angle) of the magnetic flux is estimated. Using this estimated magnetic flux as a reference, the phase of the output voltage of the inverter 1 is controlled, and in its turn, an excitation current i1d and a torque current i1q of the motor 2 (the latter corresponds to its secondary current) are controlled. Thereby, the highly accurate speed-control of the motor 2 can be performed inclusively of the region adjacent to zero-speed.

Title: Method of variably controlling speed of induction motor
Inventor: EBARA MINORU
IPC: H02P1/26
Filed: 1978-08-24
Abstract: PURPOSE: To operate variably at the speed of an induction motor over a wide range by a small capacity inverter by driving the motor in a primary frequency operation in low frequency range and in Scherbius operation in high frequency range.  
     CONSTITUTION: In case of a primary frequency operation, electromagnetic contactors 1, 5 and 9 are closed and electromagnetic contactors 7 and 8 are opened to drive an induction motor in a primary variable frequency operation by a current type inverter 3, and in case of a Scherbius operation, the electromagnetic contactors 1, 7 and 8 are closed, and the electromagnetic contactors 5 and 9 are opened. In such states, the primary power is supplied to the induction motor 6 through the contactor 7, and the secondary power of the motor 6 is regenerated at the power side through the contactor 8, the inverter 3, a transformer 2 and the contactor 1. In this case, the secondary circuit at the inverter 3 side operates as a rectifier, and the primary circuit operates as a power inverter. Since the inverter 3 constitutes at the input side circuit a rectifying circuit by a thyristor, it can control the firing phase to thereby operate the induction motor in a supersynchronous Scherbius operation to largely increase the variable speed range of the motor.
