Abstract
The invention relates to a variable speed drive (1) connected upstream to an electric power grid (R) and downstream to an electric motor (M), the variable speed drive comprising notably a main casing comprising a base (14) and a main closure cover (15) closing on the base (14), a rectifier module (10), an inverter module (11), these modules being inserted inside the casing, and one or more bus capacitors (13). The main closure cover (15) comprises one or more openings (151) each traversed by a bus capacitor (13) and the variable speed drive comprises a secondary closure cover (17) fitting onto the main closure cover (15) and covering the said one or more bus capacitors (13).
