MULTI-OUTPUT BATTERY ELECTRIC VEHICLE CHARGER WITH SWITCHED MODE POWER SUPPLY
A battery electric vehicle (BEV) charging station includes at least one power module having a plurality of switches that rectify alternating current (AC) electrical power received from a power grid into direct current (DC) electrical power supplied to a BEV; at least one switched mode power supply (SMPS) internal to the power module; and operational equipment electrically connected to the SMPS in the power control module.
A stator arrangement for an electric machine has a stator and an interconnection module. The stator includes a stator core on which a stator winding is arranged. The interconnection module electrically interconnects winding wire ends of the stator winding. The interconnection module is positioned on the stator on an end side. The interconnection module includes integral electrical terminal conductors which are embedded at least partially in a body of an electrically insulating material. The terminal conductors each form a terminal contact to which an external power supply and/or control of the stator arrangement can be connected, and a winding contact which is electrically conductively connected to a winding wire end.
A rotor for an external rotor motor is described, having a stack of ferromagnetic steel sheets, permanent magnets which are fastened to an inner side of the stack, and a carrier which has a hub for a shaft and is fastened to the stack. It is provided that the carrier is connected to the stack by a shaft-hub connection.
A housing component for an electric motor is described, comprising a stator receptacle for a stator of the electric motor and an inner part which projects into the stator receptacle. The inner part forms a sleeve for receiving a shaft of the electric motor and an inner annular space, which is arranged between the stator receptacle and the sleeve. In addition, an electric motor with such a housing component is disclosed.
