Abstract
1,120,980. Control of A.C. induction motors; two-part couplings. SKIL CORP. 27 June, 1967 [18 July, 1966], No. 29606/67. Headings H2A, H2E and H2J. [Also in Division H3] A portable electric tool such as an electric drill or screwdriver comprises a high frequency three phase induction motor 102, 103, the stator windings 102 of which are supplied from a normal mains supply by way of a frequency changer having components such as transistors 33, 34; 44, 45; 56, 57, saturable transformer 24, capacitors 116, bridge rectifier 10, these components being accommodated in the housing 98 of the tool or in a casing 108 attached to the mains plug 110. Alternatively the components may be divided between the housing 98 and the casing 108. The tool is provided with a main switch 22 operated by a trigger 100 and forward and reverse switches operated by a lever 101. Furthermore the windings on the saturable transformer 24 may be incorporated with the stator windings 102 in the stator of the motor.
