Abstract: An electric apparatus including a connector holding six connecting terminals is provided. Three one-side connecting terminals held by the connector are arranged side by side in a row substantially directly below conductive terminals of three phases of one DC-AC converter. Three another-side connecting terminals held by the connector are arranged side by side in a row at positions offset to a side away from the one-side connecting terminals in an axial direction. Upper-end side connecting parts of the three one-side connecting terminals are set to be lower than upper-end side connecting parts of the three another-side connecting terminals, and are connected to the corresponding conductive terminals above via busbars extending in an up-down direction. The upper end-side connecting parts of the three another-side connecting terminals are connected to corresponding conductive terminals via busbars extending along an arrangement direction of the conductive terminals.

Abstract: An air compressor (10) includes an air pump (34) with a pump inlet (34a) for receiving air to be pressurized and a pump outlet (34b). An air tank (14) includes a tank inlet (14a) coupled with the pump outlet (34b) for receiving pressurized air from the air pump (34), and a tank outlet (14b) for directing pressurized air from a tank outlet (14b) to at least one pneumatic device (24). A brushless DC motor (36) includes a rotatable output (36a) coupled with the air pump (34) for operating the air pump (34) to pressurize air. A control (42) is electrically coupled to the brushless DC motor (36). The control (42) changes the level of electric current drawn by the brushless DC motor (36) to thereby change the rate of rotation of the rotatable output (36a) and/or the pump performance level.

Abstract: An electro-mechanical linear actuator is provided and includes a housing. A motor is supported within the housing and includes an output shaft. A gear package includes a drive package. The gear package is configured to engage the motor such that rotation of the output shaft provides rotation of the gear package. A lead screw engages the gear package such that rotation of the gear package provides rotation of the lead screw. A nut assembly engages the lead screw such that rotation of the output shaft causes axial travel of the nut assembly. A drag link is coupled to the nut assembly such as to provide axial travel of the drag link. An electrical connector is formed as a single unitary body with the housing and is configured to receive an electrical connector in electrical communication with an external controller.
