摘要： In a motion control apparatus for an induction motor, an inclination of acceleration/deceleration curve representing an increase/decrease per unit time in rotation speed of the induction motor is changed in accordance with the value of an angular frequency .omega.s corresponding to a slip speed of the induction motor.

摘要： The acceleration/deceleration control apparatus using slip speed detects an angular frequency .omega.r corresponding to an execution speed of an induction motor and derives an angular frequency .omega.s corresponding to a slip speed corresponding to a slip speed in response to a torque of the said motor, from a vector controller of the said motor.On the other hand, an allowable value .omega.s' of said angular frequency corresponding to the said .omega.r is prepared beforehand, and is compared with said angular frequency .omega.s.According to the result of this comparison, the IM rotation is controlled. So even if the induction motor is used as servo motor, no shock of the torque will flow through the motor and the motor itself will not be stalled.

摘要： A heating unit includes a pair of heating bodies for heating a band film conveyed along a predetermined film feeding path defined by a film guide. An embossing unit includes a punch and a die for forming a predetermined raised pattern on a heated surface of the band film. A shifting mechanism locates the heating unit and the embossing unit closely by a first distance during a thermal processing of the band film and separates at least one of the heating unit and the band film far away from the other by a second distance larger than the first distance when the thermal processing is interrupted or stopped.
