The disclosed power pack of an MDPS comprises: an electric motor for converting electrical energy into kinetic energy; a connector unit having a power connector electrically connected to a power supply harness supplying driving power to the electric motor from the outside of the MDPS; a power circuit board having a circuit formed to supply driving power to the electric motor, and electrically connected to the connector unit and the electric motor; and an auxiliary power supply unit electrically connected to the power circuit board, and configured to supply driving power to the electric motor when driving power is not supplied from the power supply harness. The power pack of the MDPS can secure at least enough redundancy to escape an emergency situation even when a problem occurs with external power input.
개시된 MDPS의 파워팩은, 전기에너지를 운동에너지로 변환하는 전동모터; MDPS의 외부로부터 전동모터의 구동 전력을 공급하는 전원 공급 하네스에 전기적으로 연결되는 전원 커넥터를 구비한 커넥터부; 전동모터에 구동 전력을 공급하기 위한 회로가 형성된 것으로, 커넥터부 및 전동모터에 전기적으로 연결된 전원 회로기판; 및, 전원 공급 하네스로부터 구동 전력이 공급되지 않을 때 전동모터에 구동 전력을 공급하기 위한 것으로, 전원 회로기판에 전기적으로 연결된 보조 전원 공급부;를 구비한다.
