Abstract
A motor controller assembly is configured for use with an electric motor and includes a controller and an absorbent pad. The controller includes a capacitor with a capacitor shell and a liquid electrolyte contained therein. The capacitor shell has a frangible rupture area that opens during a capacitor rupture event to permit the discharge of liquid electrolyte from the capacitor shell. The absorbent pad overlies the rupture area to collect discharged liquid electrolyte.
