摘要： A stepping motor is energized by a power supply that supplies charges of power with the number and duration of the charges being controlled according to the current operating conditions of the motor. The charges are supplied to a capacitor across which the motor is connected for energization with the voltage developed across the capacitor being the voltage supplied the motor.

摘要： A digital circuit for translating each input command pulse into an incremental step of a digital motor in which the input pulses may be received at any rate while the pulses to the motor and hence the motor velocity are produced at rates which is within the motor's ability to change its velocity. The system uses a digitally operated circuit that can be easily adjusted to different motor velocity abilities and also enables control over both directions of motor movement.

摘要： A magnetoresistive sensor includes groups of MR elements arranged on a non-magnetic substrate for selective connection to detect and sense magnetic information recorded on a number of different diameter encoder wheels of which each diameter wheel may have a different number of pieces of magnetic information recorded at corresponding different wavelenths (.lambda.) on a circumferentially running track located on the circumferential face of the wheel. The MR sensor includes an additional MR element arrangement for detecting and sensing index magnetic information recorded on an additional circumferentially running track located on the circumferential face of the wheel. The connection arrangement of the MR elements is such to form external power supply connection terminals which have a width substantially larger than the width of the MR elements and surround the MR elements covering a substantial portion of the substrate surface to form a heat sink to eliminate thermal gradients from developing across the substrate thereby providing thermal stability.

摘要： Two-phase voltage signals for use with a resolver-to-digital converter (RDC) are produced as a periodic function of permeance developed across an air gap between a rotor and stator wherein the permeance varies as a periodic sinusoidal function which can be related to the electrical angle of the position of the rotor. The two-phase voltage signals are developed as a function of inductive reactance and follow the form ##EQU1## wherein the phase angle between V.sub.x and V.sub.y is exactly 90.degree. and the term [A+A.sub.n +B+B.sub.n ] is completely free of second harmonics.

摘要： An up/down counter interface converts input information suitable for the operation of one type up/down counter, which type receives input information in the form of a direct current logic signal indicating direction and a train of electric pulses representing increments of information, to input information suitable for the operation of a second type up/down counter, which second type receives input information in the form of two identical pulse trains representing increments of information, direction being determined by the relative displacement in time of the two pulse trains.

摘要： A coil for a variable transformer is provided having multiple layers of wire. Winding of such a coil is facilitated by providing an end form having a series of raised fins, or partitions, between which stacked layers of wire are held. The construction provides for easy and economical machine-winding and ensures that the segments of wire forming the commutating surface are held relatively immovable with respect to each other, thus preserving the integrity of the commutating surface.

摘要： An electromagnetic device of the type having a rotor and a stator with magnetically coacting peripheries, with the stator having toothed pole structures, has the stator pole teeth set at nonuniform spacing to improve the operating characteristics of the device. When the device is a stepping motor, improved step accuracy is attained through reduction of residual (or detent) torque. Reduction of airborne noise is reduced in all motor types.
