| 摘要 |
The invention relates to a driving arrangement preferably for automatic washing machines, having a commutator motor (3) supplied from a single-phase AC power supply, its speed controlled via a TRIAC (1). The iron and commutation losses occurring during low-speed operation can be reduced by using an uncontrolled, full-wave rectifier arrangement (bridge rectifier 2), connected between the output terminals (11, 12) of the TRIAC (1) and the input connections (32, 32) of the motor (3). Preferably, the TRIAC is IC-controlled. <IMAGE> |
