Asynchronous motor controlling device for e.g. roller blind, has interruption unit arranged on lines supplying coils of motor and provided with current for supplying microcontroller and for indicating desired rotation direction of motor
The device has an interruption unit (3) arranged on lines supplying coils (L1, L2) of an asynchronous motor (1) and controlled by a microcontroller (100). The interruption unit is provided with current for supplying the microcontroller and indicating a desired rotation direction of the motor. A power supply (10) has capacitors (Cx, Cy) ensuring sufficient energy quantity during disconnection of the supply from the microcontroller. A zener diode (Z1) determines a voltage level at an input of the supply.
