Abstract:
An electric motor is provided. The rotor includes a rotor shaft, with a bearing rotatably supporting the rotor shaft. A bearing housing is interposed between the bearing and the motor frame assembly. The bearing housing is releasably connected to the motor frame assembly so as to be selectively secured in supporting relationship with the bearing and thereby the rotor. The motor frame assembly includes a circumferentially extending support face. The bearing housing presents a circumferentially extending engagement face which engages the support face when the bearing housing is in the supporting relationship. At least one of the faces is axially tapered to facilitate axial movement of the bearing into the supporting relationship.
Abstract:
An electric motor is provided. A rotor sensor mechanism is operable to sense a condition of the rotor. The rotor sensor mechanism includes a target component, a radial sensor, and a sensor carrier. The target component comprises a shutter wheel fixed relative to the rotor for rotational movement therewith. The shutter wheel includes a plurality of circumferentially spaced, radially projecting radial target teeth. The radial sensor is configured to sense the target teeth. The radial sensor is at least generally axially aligned with the radial target teeth and faces radially toward the radial target teeth. The sensor carrier adjustably supports the radial sensor on the motor frame assembly so as to permit the radial sensor to be selectively positioned relative to the radial target teeth.
Abstract:
An electric motor is provided. The motor includes a motor frame assembly including a motor frame and a motor housing. A stator is fixed relative to the motor frame assembly. A rotor including a rotor shaft is mounted in the motor frame assembly for rotational movement relative to the motor frame assembly about an axis. A rotor jack is operable to selectively support the rotor shaft. The rotor jack is shiftably coupled relative to the motor frame assembly for movement between a support position, in which the jack is shifted into supporting contact with the rotor shaft, and a retracted position, in which the jack is spaced from the rotor shaft.
