Abstract
A motor-driven compressor includes a housing, a compression portion, and an electric motor, a drive circuit, a circuit housing, a control circuit, a communication lead, and a metal shielding member. The compression portion and the electric motor are received in the housing. The circuit housing is arranged outside the housing and defines an accommodation chamber that receives the drive circuit. The control circuit is configured to control the electric motor by controlling the drive circuit. The communication lead is connected to the control circuit and drawn from the inside to the outside of the accommodation chamber. The metal shielding member is arranged in the accommodation chamber and covers the communication lead. The circuit housing includes a metal shielding portion, which is electrically grounded. The shielding member is electrically connected to the shielding portion.
