Electric motor assembly rechargeable from an electrical mains system, and dedicated connection housing

摘要

An electric motor assembly includes a multi-phase electric motor, a battery of accumulators, an inverter configured to convert the direct current of the battery into multi-phase alternating current adapted to supply the motor, and a connection housing. The connection housing includes plugs allowing connection of motor phases, the battery terminals, and at least five connections to the inverter. The housing further includes a group of contacts allowing it to be connected to a single phase mains system, and a group of contacts allowing it to be connected a multi-phase mains system. The housing includes switches according to the position of which the system including the housing, the battery, the inverter, and the motor connected solely by its phases, alternatively allows the motor to be supplied from the battery, the battery to be recharged directly from a single-phase mains system, and the battery to be recharged from multi-phase mains system.
