<p>The invention is applicable in the field of control devices for direct current motors supplied from batteries. It consists of a box 1 whose volume is divided, by an electronic power card 9, into two compartments 10 and 11, one above the other. In the lower compartment 10 are housed transistors and diodes that generate heat, in the upper compartment 11 are housed capacitors and an electronic control card 13. The transistors and diodes are mounted on a metal bar with an essentially triangular cross section fixed to the base of the box to encourage the dissipation of heat. <IMAGE></p> |
