Abstract

1400538 Control of DC motors; electric protective arrangements DEL MAR ENG LABORATORIES 18 Oct 1972 [29 Nov 1971] 48007/72 Headings H2J and H2K [Also in Division A6] An exercise treadmill is driven by a D.C. motor 12 controlled by a unit 20 comprising a speed control rheostat 22, and an on-off switch 24 which, after it has been switched into its off position, cannot then switch the motor on again until the control rheostat 22 is returned to its zero-speed position. Fig. 3 shows a mechanical interlock in which a pinion 26 coaxial with speed control 22 engages a rack or a slide 32, one end of which enters a space 42 above a spring- biased latch 44 having an inclined surface 46. Button 40 cannot be switched on unless pinion 26 is turned fully anti-clockwise. Fig. 6 shows an alternative interlock constituted by an electrical circuit having a switch 56 which is closed only when control rheostat 22 is in its zero-speed position. Upon closure of twopole switch 24 one pole permits energization of relay coil 54 to close relay contacts 50, and the other pole keeps the relay closed when the switch 56 is subsequently opened. Relay 50 feeds A.C. power to a control module 18 which includes an SCR bridge rectifier 19 and a safety circuit 62. If the voltage applied to the motor 12 exceeds the voltage set by control rheostat 22 by more than a predetermined amount, e.g. due to failure of an SCR, then to prevent sudden acceleration of the treadmill, safety circuit 62 opens the switch of a relay K1 connected in series with switch 56 and the coil 54 of relay 50
