In an image reproducing apparatus with electromagnetic beam deflection of the picture tube (10) occurring as a function of an image synchronizing signal (BSN) and with a blower (20), the motor (18) of the latter is designed as a phase-shifting asynchronous motor to avoid image interferences due to magnetic leakage fluxes, in which motor the current supply takes place in a bridge circuit (50) controlled as a function of the image synchronizing signal (BSN) in such a way that the rotary field of the motor (18) is synchronous to the image synchronizing signal (BSN). |
