Abstract

1484296 Control of A.C. motors SIEMENS AG 11 Sept 1974 [28 Sept 1973] 39705/74 Heading H2J A washing machine is driven by a serieswound A.C. commutator motor M energized from an A.C. supply RMp through a Triac 1, which is controlled by members 4, 5 to obtain a desired motor speed n during washing or spinning, the change from a higher to a lower speed being obtained by closing a normally open switch S2 to short circuit the armature 2 (via reversing switch S1 and connect the field winding 3 in series with the Triac 1, which is controlled to produce a desired variation of braking torque with speed. Thus the decrease with decreasing speed of the braking torque due to friction on the washing drum can be compensated by controlling Triac 1 to increase the electrical braking torque with decreasing speed, up to a maximum permissible field current, Fig. 2 (not shown). Such control also results in a constant armature current during braking. Alternatively Triac 1 may be controlled to vary the braking torque in accordance with a predetermined function of time.
