Abstract
904,755. Control of A.C. motors. REIFENHAUSER G.m.b.H. March 6, 1959 [April 5, 1958], No. 7931/59. Class 38 (3). Tubing is cut into predetermined lengths by means of a sickle-shaped shear driven by a squirrel-cage induction motor 15 having a mechanical brake which is capable of slipping. The tubing is continuously advanced past the shears, and a photo-electric switch 33 is closed when the front end of the tube reaches a predetermined position corresponding to the length which it is desired to cut. Closure of switch 33 closes a contactor 14 for energizing the motor 15 and releasing the brake, the motor reaching full speed after its shaft has turned through a predetermined angle. The cutting operation is performed whilst the motor is rotating through a further predetermined angle, whereupon a switch 6 is depressed by a motordriven cam to de-energize the motor, apply the brake, and to open the contactor 14. The motor is brought to a standstill when it has completed substantially one complete revolution. The switch 6 is held in its depressed position by means of a spring-biased latch 11, and, when the switch is depressed, a time-delay relay 26 is de-energized so that solenoid winding 29 is energized for a short period. This withdraws the latch 11 and allows the switch 6 to re-close its contacts, the circuit for the solenoid winding 29 being then broken.
