Title: Slip frequency compensating method of induction motor
Inventor: YO KO
IPC: H02P27/06
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To execute slip compensation, without execution of feedback control and use of a complicated read circuit, by setting a ratio of a magnetic flux component current to a torque component current to a particular value in the direction of a primary current to calculate a slip compensation value depending on an amplitude of the primary current of an induction motor. SOLUTION: In a speed controller of an induction motor, which executes full-wave rectification for a 3-phase power source with a converte 1 and smoothing the rectified power source with a capacitor 2 to connect to an inverter 3 and also comprises an arithmetic unit 6 and a PWM pulse generator 7 operating depending on a frequency command 5, a current value detected by a power source detector 8 is input to the arithmetic unit 6. Here, a compensating value for the slip frequency of the induction motor 4 is calculated by setting a ratio of the magnetic flux component current to a torque component current to 3:7, under the condition that the magnetic flux component current shall not change rapidly for the change of a load and the magnetic flux component current is equal to the rated magnetic flux component current.  Thereby, slip compensation which is sufficiently reliable for practical use may be realized very easily.

Abstract: PURPOSE:To attain reel servo of certain tape speed by using the fact that the repeat period of a pilot signal extracted from the reproduced signal obtained from a rotary head corresponds to the tape speed and applying reel servo which controls a reel base driving motor so that said period is a prescribed value.

Consequently, a switch circuit 32 is switched by an inversion signal INV shown in a figure H, and a signal having the period corresponding to the tape speed for 4-fold speed reproducing is obtained as a signal SE from the switch circuit 32 as shown in a figure I. Since rotary heads HA and HB scan across tracks, whose number corresponds to the tape speed, for variable speed reproducing, the signal of the period corresponding to the tape speed is obtained as the output SE of the switch circuit 32 in all kinds of tape speed similarly. Thus, this output signal SE is used to apply reel servo of certain tape speed.
