    摘要: A rotor is comprised of laminations forced on a shaft that has two staking rails, which penetrate the laminations and create two holding points. The two staking rails are positioned on the shaft at an angle to force the lamination toward the center of the shaft and force it hard against a flat on the shaft. This assembly provides for "zero" rotational movement without additional steps in the manufacturing process. An additional feature of the assembly is that the flat on the shaft relates to flats on the rotor to which the permanent magnets are attached, and a flat on the shaft for mounting an encoder, which flats are all in the same plane. This allows the motor to be easily aligned, which is a requirement to properly phase motor rotation to motor commutation.

    摘要: A high-speed printer includes a standard printing element, such as a daisy wheel, a paper feed mechanism and a ribbon feed mechanism. All of these various devices are controlled by a single linear actuator which comprises an elongated cylindrical magnet, C-shaped in cross-section, through which a ferrous core axially extends. A plurality of separate armatures envelope the core in the air gap between the magnet and core and are adapted to move linearly upon application thereto of a control current. The armatures control, respectively, the movement of the carriage containing the printer element, the rotation of the printer element, the advancement of the paper feed mechanism and the incremental positioning in both directions of the ink ribbon.

    摘要: A vacuum chuck apparatus includes a vacuum chuck mounted on one end of a hollow shaft whose other end is connected through a rotary seal to a vacuum source. The seal includes a first member having a cap portion cemented to the shaft end and an axially bored frustoconical projection on its end wall and a second member having a frustoconical socket complementing the projection which partially nests in the socket. The second member has a radial pin loosely engaging a longitudinal slot in a stationary bracket to restrict its rotation and permit its axial movement. A spring loaded pressure plate bears on the outer end face of the seal second member.

    摘要: Heat-conductive masses of material encapsulate end turns of a stator fixed in a housing of a motor to dissipate heat from the stator through the side and one end of the housing. In one embodiment, a resilient heat-conductive pad is interposed between a front plate of the housing and a side of one of the heat-conductive masses of material facing the front plate. The pad has a thickness greater than the manufacturing tolerances associated with assembling an end of the stator at an end of the housing adjacent to the front plate. In another embodiment, the heat-conductive mass of material adjacent to the front plate extends into contact with the front plate. The contact can be assured, even without the presence of a resilient pad, by forming the heat-conductive mass between the stator and the front plate after the stator is assembled to the housing.

    摘要: A motor, encoder/resolver, and/or dynamic brake assembly in which the dynamic brake, when part of the assembly, is mounted on a rear cover plate of a modular housing for the auxiliary components. When a resolver or encoder is part of the assembly, the motor shaft extends only a short distance beyond the resolver/encoder housing module; far enough to be engaged by the armature of the dynamic brake if the brake is part of the assembly. In an assembly that does not use a dynamic brake, the same rear cover plate is used to close the encoder/resolver housing module.

    摘要: A door lock security system is disclosed in which each lock in a multiple lock system is modified by the addition of door lock security apparatus which, in electrical form, stores at least an individual key combination (and possibly several different levels of master key combinations) for the lock. Also, the conventional lock cylinder is replaced with a cylinder assembly which senses the magnetic reluctance state (high or low) of predetermined locations on a key substantially resembling a conventional cylinder lock key in size, weight and general shape and capable of mechanically operating the lock. The magnetic reluctance states of the predetermined locations digitally encode the key combination and the thus encoded combination is compared to the electrically stored one, disabling the mechanical operation of the lock unless the two combinations are identical. The electrical combination storage means within the door lock security apparatus may be placed in an adaptive state in which the combination of the next key inserted into the lock is stored as the lock combination and, thereafter, only a key with that combination will operate the lock. There is also provided an emergency key which overrides all other keys and, at any time, can operate any lock in a multiple lock system. This emergency key generates a time varying electrical signal which enables operation of any door lock despite its stored combination.
