Abstract: A device may include a first end, a second end, and a coupler configured to extend through an aperture from a first side to a second side of a motor cover. The coupler includes a head portion, a conduit portion extending from the head portion towards the second end, and a first bore axially extending through the coupler. The device may include a brush holder extending through the first bore. The brush holder includes a cylindrical body, a socket at the first end, and a receptacle at the second end. The device may include a first lock nut including a first threaded bore axially extending through the nut. The device may be configured to enable a grounding brush to contact a motor shaft to provide a current discharge path to ground to reduce an erosion of the motor components including the motor shaft and rolling bearing elements.

Abstract: A sintered magnet, the sintered magnet including a core portion, a shell portion arranged at an outer part of the sintered magnet, and a diffusion portion arranged at least partially between the core portion and the shell portion. The shell portion has a coercivity, which is at least 30 kA/m larger than the coercivity of the core portion. In the diffusion portion, the coercivity is not less than the coercivity of the core portion and not larger than the coercivity of the shell portion and the value of the coercivity gradually increases from the core portion towards the shell portion. The thickness of the core portion is not less than 1 mm and the total thickness of the shell portion and the diffusion portion is at least 5 mm.

Abstract: A hybrid rare-earth-iron-boron hard magnetic material is constituted of two materials, a first magnetic alloy of chemical composition Nd12±0.2Fe82±0.2B6±0.2 in atomic percent with each single particle surrounded and chemically bonded to a second material constituted by copper, zinc, or a mixture of the foregoing such as brass alloys. The mixture of the first and second materials is magnetically oriented, compacted and densified such as through sintering, to optimize its mechanical and magnetic properties.
