<p>The electronic speed controller includes a casing (1) housing a rectifier (4) supplied with alternating current, associated with capacitors (3) for supplying continuous voltage to an oscillator (2). The oscillator (2) consists of a number of power modules (21) with static interruptors controlled by an electronic control circuit (52) to deliver an alternating voltage. The power modules are mounted in an internal envelope made of plastic material cooperating with an electrical connection board (51) connecting the modules (21) and the capacitors (3) with a radiator (7). This forms an unsealed chamber for the power modules (51).</p> |
