摘要： A stepper motor, having a permanent magnet rotor rotatably mounted within the annulus of a stator winding, also has a rotatable spring magnet and a stationary bias magnet. The spring magnet is attached to the rotor and is disposed adjacent the stationary bias magnet. When the stator winding is not energized, the rotor assumes a home position established by the spring and bias magnets. When the stator winding is energized, the rotor is rotated away from the home position by an angular displacement determined by the winding current.

摘要： A stepping motor with toothed stator poles and toothed rotor poles is magnetically enhanced by locating permanently magnetized inserts in the spaces between the stator teeth and magnetizing the inserts transverse to the direction of movement of the rotor and substantially transverse to the direction in which the teeth extend. In a hybrid motor with a split and axially magnetized rotor the inserts are magnetized to oppose the magnetization of the rotor. In a variable reluctance motor with an unmagnetized rotor inserts are placed in both rotor and stator and magnetized to aid each other. Linear motors use either configuration.

摘要： A positioning mechanism for moving a cylinder axially and rotationally is adapted for a printer which has a cylindrical type carrier on which the dies are arranged in intersecting rows and columns. A first electrically conductive coil is coaxial with and mounted on one end portion of the cylinder. A second electrically conductive coil has an axis perpendicular to the axis of and is mounted on the other end portion of the cylinder. A pair of permanent magnets are positioned about opposite end portions of the cylinder such that each coil is disposed for magnetic coupling in the magnetic flux field of a corresponding magnet. By selectively energizing the coils, magnetic effects are produced thereabout for coaction with the permanent magnetic flux fields simultaneously to drive the cylinder axially of and angularly about its axis. A feed back system for sensing the instantaneous longitudinal and angular positions of the cylinder is adapted simultaneously to provide electrical effects, whereby from any axial and angular conditions the cylinder can be driven to any other selected axial and angular conditions.

摘要： An approach to a reduced-head hard disk drive (HDD) involves an actuator subsystem that includes a ball screw cam assembly wherein the number of starts of a multi-start screw equals the number of balls riding in a corresponding start. A stepper motor may be disposed within the screw, to drive rotation of the screw, which drives translation of an actuator arm assembly so that a corresponding pair of read-write heads can access different magnetic-recording disks of a multiple-disk stack. The actuator subsystem may further include a cam locking mechanism for coupling and decoupling the actuator arm with a coil support structure and corresponding voice coil, so that the cam mechanism is able to move under the control of a voice coil motor when input/output operations are performed and is able to move the actuator arm assembly during translation operations.

摘要： A stepper motor is provided in which a permanent ring magnet is sandwiched in an outer part of the stator winding assembly located far from the gap between rotor and stator teeth, so that magnetic flux in the gap is dominated by the Ampere-turns of energized stator coils and therefore more easily controlled for reduced vibration at low stepping speeds. The rotor need not contain any permanent disk magnet. If one is provided, it can be completely embedded within the rotor and merely supplement the primary flux from the stator to enhance torque. In most cases, where the rotor lacks any permanent magnet, the motor's axial shaft can have a larger diameter and may, together with the rotor, form a linear actuator.

摘要： A permanent magnet (PM) machine has a reconfigurable fault condition mechanism disposed solely within a stator core portion, wherein the mechanism is automatically reconfigurable to reduce fault currents associated with the PM machine during a fault condition. The reconfigurable fault condition mechanism is automatically reconfigurable to also reduce internal heat associated with the PM machine during a fault condition. A method of reconfiguring the fault condition mechanism upon detection of a fault condition includes the steps of 1) selecting the reconfigurable fault condition mechanism from a) a plurality of rotatable magnetically anisotropic cylinders disposed within stator core slots, b) a plurality of ferrofluid-fillable cavities associated with stator core slots, and c) a sliding shield within the stator core; and 2) reconfiguring the fault condition mechanism to automatically reduce fault currents associated with the PM machine upon detection of a fault condition.

摘要： Using this invention, no input fuel is required to sustain operation of electric generators and other machines and devices. This is done using a magnetic motor that has parallel and perpendicular, rotatable shafts and gears to which those generators and other machines are connected along with equally spaced, perpendicular extensions having permanent magnets attached to those extensions and arranged so as to allow repelling magnetic interaction; and where the shafts also have ways of maintaining required spacing and rotational timing to allow the magnets to interact in precise and extremely close proximity a number of times per rotation causing perpetual movement.
