摘要： A coil assembly for an electric motor having an encapsulation body includes a fixing cage, a winding region, and encapsulation material. The fixing cage, a rear side of which is open, has an inner side and an outer side, between which a circumferential receiving region is defined. The winding region is arranged in an end region of the coil assembly and over which the fixing cage is placed at the end such that the winding region is arranged in the receiving region. The fixing cage and the winding region are embedded in the encapsulation material.

摘要： A power tool is provided including: a housing including a battery receiving portion configured to receive a removeable power tool battery pack and a motor housing; a brushless direct-current (BLDC) motor disposed within the motor housing, the motor including a stator and a rotor; a power switch circuit disposed between the battery receiving portion and the motor; and a controller that controls a switching operation of the power switch circuit to regulate a supply of power from the battery pack to the motor. At tool start-up, the applies a series of voltage pulses to the motor and measures a corresponding series of motor phase current values to identify an initial position of the rotor relative to the stator. Further, the controller identifies at least one of an impedance or a capacity of the battery pack as a function of the motor phase current values.

摘要： A rotating machine assembly includes a rotating machine that has a cover that defines an outer surface of the rotating machine and a stator disposed within the cover. The stator is stationary with respect to the cover. The rotating machine also includes a shaft rotatably disposed at least partially within the cover so as to define a rotation axis. The shaft Includes a first end that is connectable to an aircraft engine and a second end that is opposite the first end. The rotating machine also includes a rotor attached to the shaft, the rotor being movable with respect to the stator and a power module including at least one MOSFET that periodically reverses an electrical current direction of the rotor. The power module includes the at least one MOSFET Is disposed within the cover.

摘要： An electric generator protective cover has a protective cloth cover, a cover assembly, and a plurality of fixing feet. The cover assembly includes a central block located in the center of the top and four elastic supporting rods fixed to the central block. The protective cloth cover is jacked up through the central block and the four elastic supporting rods. One end of each fixing foot is connected to an elastic supporting rod, and the other end is mounted on an upper cross bar of an electric generator frame. The electric generator protective cover has the advantages that the protective cloth cover is arranged, which can isolate dirt such as rain, snow, mud, and sand.
