Abstract

Noise reduction device for adjustable speed collector engines used in household appliances.The speed adjustment is performed using a converter based on a triac (1). It has energy storage resources (3) during the intervals in which the triac (1) conduces and resources (3) for releasing the accumulated energy towards the engine M in the intervals in which the triac does not conduce.Additionally, it includes resources (2) that prevent the return of the energy stored during the triac (1) conduction intervals. All this in order to obtain a greater continuity in the energy supplied to the engine.The resources (2) are composed of a single-phase rectifier not controlled by jumpers.The resources (3) are determined by a bobbin (L) that can be combined with a condenser C and a resistance R1.Additionally, in parallel to the excitation coil Lm of the engine M, a resistance R2 can be included.
