Abstract
1365980 Control of two AC motors HERBERT MORRIS Ltd 14 Dec 1972 [17 Dec 1971] 58869/71 ÀHeading H2J Two motors are used in a drive for a hoist or similar device, a squirrel cage motor D having disc motor E, F, mounted on its shaft together with a drum brake C, the drive being transmitted by gear-box A to a rope drum B. In operation the disc motor is energized first to rotate the shaft, then the squirrel cage motor is switched on for high speed winding, the disc motor being disconnected. The reverse procedure is used for slowing down the drum, the brake being applied to stop the shaft and hold the load. The position of the motors on the shaft may be reversed (Fig. 2, not shown), and the disc may have ferrous and non-ferrous portions (Fig. 3, not shown). In a further modification (Fig. 4, not shown) the drum brake is replaced by a caliper brake acting on the disc (G).
