Title: Improvements in and relating to conveyor drives
Inventor: ENTWISTLE HERBERT
IPC: H02P5/74
Filed: 1950-12-21
Abstract: 697,478. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 3, 1951 [Dec. 21, 1950], No. 31129/50. Class 38 (iii) [Also in Group XXX] A method of sharing the load between the driving pulleys in a conveyer belt drive in which the belt is driven by more than one pulley, the pulleys being arranged in tandem and each pulley being separately driven, consists in driving each pulley either directly or through gearing from a wound-secondary A.C. induction motor, the various motors being connected electrically in cascade, and mechanical coupling between the pulleys being afforded by the friction between the pulleys and the conveyor belt. As shown, conveyer belt 1 is driven by pulleys 3, 4 each of which is driven by a wound-secondary A.C. induction motor 5 or 6 respectively. The motors are wired in cascade, i.e. mains to stator of motor 5, secondary windings of motor 5 via slip rings to slip rings and hence secondary windings of motor 6, and stator of motor 6 being connected by a switch 7 either to a shorting connection 9 for normal running, or to a rotor resistance starter 8, for starting. The motors 5, 6 are constructed with matched windings such that their power can be determined by the numbers of their poles. The relative powers necessary to ensure that neither driving drum 3 or 4 slips if the other drum could be given more power without slipping are determined in accordance with the coefficients of friction between the belt and either pulley and the angles of lap of the belt around each pulley by a formula and it is shown that for equal angles of lap around the pulleys 3, 4 of 180 degrees and coefficient of friction of 0.35 the relative powers of the motors 5 : 5 would be 3 : 1. Thus, e.g. motor 5 may have twelve poles, and motor 6 four poles.
