摘要：The invention concerns a method for varying and regulating the speed of amotor powered from a voltage source via a triac, comprising, at least once every
alternating voltage interval, the following steps: computing a surface value (S)
corresponding to the current absorbed (I(M)) in a time window (FT) defined between acurrent switching-on time (t) and a following current switching-off time (t); computing aninterval of the next triac-blocking time (t′); and controlling the starting of the triac whenthe blocking time (t′) has elapsed. The invention is useful in particular for householdelectric and house automation appliances operating at variable speed.
