摘要： An electric motor is provided including a stator, a rotor, a motor spindle coupled to the rotor and extending along a center axis, a first end cap formed on a first side of the stator, a second end cap formed on a second side of the stator and secured to the first end cap to form a first compartment around the stator and the rotor, and a motor component mounted on the second end cap outside the first compartment. A motor cover is mounted on the second end cap to form a second compartment around the motor component. The first end cap, the second end cap, and the motor cover form a substantially watertight seal around the stator, the rotor, and the position sensor assembly.

摘要： An electrical machine, which may be a motor and/or a generator has a rotor mounted to rotate about an axis. A plurality of magnetic poles are spaced circumferentially around the rotor in the bore. The rotor comprises a shell shaped to provide a toroidal bore centered on the axis. A slit extends circumferentially around the rotor. The slit penetrates through the shell into the bore. The electrical machine also includes a stator that is supported in the bore by one or more supports extending through the slit of the rotor. The stator carries plural windings that are spaced apart around the bore.

摘要： A motor for a laundry apparatus includes a stator and a rotor including a rotor frame which rotates outside the stator. The rotor frame includes a base frame having a circular shape and disposed with a distance from a coil, an extension frame which fixes a magnet, an air inlet which suctions air, and a blade protruding to a set height from the base frame, and the blade is positioned outside a region in which the coil is disposed. According to the present disclosure, the heat dissipation performance of the motor can be improved while maintaining the strength of the rotor frame, and motor output can be improved by sufficiently securing a winding space of the coil.

摘要： A DC electric motor having a stator mounted to a substrate, the stator having a coil assembly having a magnetic core, a rotor mounted to the stator with permanent magnets distributed radially about the rotor, the permanent magnets extending beyond the magnetic core, and sensors mounted to the substrate adjacent the permanent magnets. During operation of the motor passage of the permanent magnets over the sensors produces a substantially sinusoidal signal of varying voltage substantially without noise and/or saturation, allowing an angular position of the rotor relative the substrate to be determined from linear portions of the sinusoidal signal without requiring use of an encoder or position sensors and without requiring noise-reduction or filtering of the signal.

摘要： A stator includes a first sleeve extending in an axial direction and a first stator core on an outer periphery of the first sleeve. The first stator core includes a lower core and an upper core on a side of the lower core opposed to a first end of the axial direction. The lower core includes a lower annular portion with an annular shape and lower pole teeth protruding radially outward from a radially outer end surface of the lower annular portion and extending to a second end of the axial direction. The upper core includes an upper annular portion with an annular shape arranged on the lower annular portion opposed to the first end of the axial direction to overlap the lower annular portion, and upper pole teeth protruding radially outward from a radially outer end surface of the upper annular portion and extending to the second end of the axial direction. Each of the lower pole teeth and each of the upper pole teeth are alternately arranged in the circumferential direction.

摘要： A liquid-cooled rotating electric machine may include an inner stator and outer rotor configured to rotate about the stator. A hub may be disposed within the inner stator and a heat exchanger may be disposed in the hub. The heat exchanger may be configured to enable the flow a liquid through it to dissipate heat from the stator.
