An arrangement with an electric motor facilitates mounting of the motor, particularly of a miniature or subminiature motor. The motor (20) has a stator (56), a rotor (24), and a support flange (36) coupled to the motor. A motor mount (22) is formed with an opening (94) for engagement with the support flange (36). The opening has, on its rim, a motor-side shoulder (96) that has a substantially frustoconical shape and faces axially toward the motor (20) after mounting. The support flange (36) is s...

The invention relates to a spring element (10) for compensating for axial play in a motor shaft of an electric motor. The invention proposes embodying such a spring element (10) out of plastic and of one piece with a stop disk (12), which is connected via spring arms (14) to a support foot (16), and placing it, along with the support foot (16), onto a support sleeve (18) with which the spring element (10) can be press-fitted onto the motor shaft. The invention has the advantage that it eliminate...

An electrical alternator includes a stator with circumferentially-spaced stator arms, each having a coil wound on it. The rotor includes a cup-shaped support component with a plurality of magnets affixed to the inner surface of the component rim so as to be in excitation relationship to the coils. The improvement comprises a hub including (a) a first hub portion having the stator affixed thereto, and (b) a second hub portion axially spaced from the first hub portion. A ribbed section is affixed ...

A rotor. The rotor includes a case, a reinforcing part, a shaft and a connecting element. The reinforcing part is formed with the case and defines an opening. The shaft extends into the opening. The connecting element connects the case and the shaft, with the reinforcing part disposed inside.

An adjustable motor mount has two interlocking base plates and turned-up yokes which are attachable to axially projecting end bell hub portions of a motor. The interlocking base plates are slidably engaged one to another and may be axially adjusted to accommodate motors of different axial lengths. The axial expansion feature of the invention may also be used in conjunction with motors having dual hub mounting portions to provide either rigid or resilient support.

A tachometer is mounted to an end frame of a motor. The end frame includes an end mount plate. An adjusting plate located within the recess and coupled to the mount plate through a plurality of radial coupling units and a plurality of axial spring loaded clamp units. Both coupling units are circumferentially spaced about the mount plate and the adjusting plate. Each radial coupling unit includes radial set screws in threaded openings in the mount plate and engage the periphery of the adjustment ...

A throttle body assembly including an end plate. The throttle body assembly includes a housing having an inner wall, and a motor located within the housing. The motor end plate is coupled to the motor and is in contact with the inner wall of the housing. The end plate includes an outer edge having at least one protrusion extending therefrom. The contact between the end plate and the housing is substantially only between the at least one protrusion on the outer edge of the end plate and the inner...

A rotor of motor for drum type washing machine comprises a stator formed of a field winding; a rotor disposed outside the stator to house the stator, and having a yoke surface on which a permanent magnet for performing a magnetic interaction with the field winding of the stator, the rotor rotating around the stator; a shaft bushing for connecting the rotor and the rotation shaft, which is installed on the bottom surface, wherein a plurality of the rotation groove portions whose width of one side...

A motor driven electrical device includes: a variable electrical device having a rotational variable control; a first support plate positioned above the variable electrical device; a motor support plate pliably attached to the first support plate using a pliable separator positioned between the motor support plate and the upper support; a motor mounted on the motor support plate, the motor having an output shaft; an interface/control unit coupling the output shaft to the rotational variable cont...

A frameless torque motor with a transport securing device wherein the torque motor includes a ferromagnetic primary element and a secondary element, having magnets oriented in a direction toward the primary element, wherein the primary element and the secondary element are fixed to each other by a magnetic force generated by the magnets. A transport securing device that maintains the magnets spaced apart from one another, wherein the transport securing device includes a spacer in an air gap betw...
