Electric motor assembly rechargeable from an electrical mains system, and dedicated connection housing
First Claim
1. An electric motor assembly comprising:
- a multi-phase electric motor including stator coils permanently connected to a neutral point;
a battery of accumulators;
an inverter configured to convert direct current of the battery into multi-phase alternating current adapted to supply the motor; and
a connection housing comprising plugs allowing connection of the motor phases to the housing, the battery phases, and at least five connections to the inverter,the housing further comprising a group of contacts allowing the housing to be connected to a single-phase mains system, and comprising a group of contacts allowing the housing to be connected to a multi-phase mains system,the housing further comprising a group of switches according to a position of which the system comprising 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 a multi-phase mains system.

Abstract
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.
