摘要： A stator for an electric machine includes a stator core defining an axial direction, a first end, and a second end. The stator core includes a plurality of slots formed between a plurality of teeth, wherein each of the plurality of slots extend from the first end to the second end of the stator core and define a slot opening on a radially inward portion of the stator core. A plurality of conductors are positioned in each of the slots and are connected together to form a winding arrangement for the stator. A wedge is positioned in each slot of the stator core radially inward from the plurality of conductors positioned in said slot. The wedge includes a first leg positioned on one side of the slot, a second leg positioned on an opposite side of the slot, and a bridge spanning across the slot opening.

摘要： A power tool is provided including a tool housing including a motor housing and a handle portion; a battery receptacle disposed at an end of the handle portion opposite the motor housing, the battery receptacle being configured to receive a battery pack; and a brushless DC motor including a stator and a rotor. The stator includes a stator lamination stack, an end insulator, and input terminals supported by the end insulator. A power circuit board is coupled to the input terminals to supply power to the motor. The motor produces a maximum power output of at least 1600 watts for driving an output shaft at a maximum torque of at least 30 inch-pounds and a maximum speed of at least 8000 rotations-per-minute.

摘要： A stator assembly and stator for a motor is provided that directly installs in a conductor slot a slot wedge having a width approximately the same as the width of the conductor slot. The slot wedge is limited in three directions, circumferential, radial, and axial, by means of cooperation between a slot wedge pressing ring, a conductor, and a sidewall of the conductor slot, and at the same time, the slot wedge is capable of preventing the conductor from falling out of the conductor slot. In addition, in the stator assembly for a motor disclosed, when the slot wedge is installed, the slot wedge may not only be inserted and installed in the conductor slot along the axial direction, but may also be inserted and installed in the conductor slot along the radial direction, and thus, the installation mode is flexible, which may improve the installation efficiency.

摘要： A coil component for an electric machine, having a carrier and a coil winding accommodated in the carrier at least in sections. The carrier has a ring region with multiple grooves distributed in a circumferential direction, and multiple winding sections of the coil winding are received in each groove. An insulation layer is arranged between the carrier and the winding sections in at least one groove and projects with two extension portions over the winding sections towards a radial opening of the at least one groove. A closure element is received in the carrier in the groove with the insulation layer towards the radial opening, and both extension portions are arranged such that the closure element is spaced apart from the carrier by the extension portions. An electric machine is provided with the coil component.

摘要： An electric motor includes a slot insulation member arranged in a slot between adjacent ones of coils in a circumferential direction of a yoke. The slot insulation member is a wedge-shaped spacer and includes a main body and projections. The projections are arranged in the slot and projected from the main body. The coil includes a main coil portion, a coil end, and a bent coil portion. The main coil portion is arranged in the slot and sandwiched between a corresponding one of the projections and a corresponding tooth. The coil end is arranged outside the slot and contacts the main body. The coil end is wider than the main coil portion. The bent coil portion connects the main coil portion and the coil end.
