摘要： A linear motor having a more preferable braking function is realized with a low cost. A linear motor has a slider and a stator. A driving winding is wound around the slider. A plurality of permanent magnets forming magnetic poles which invert at a predetermined period are provided on a surface of the slider opposing the stator. Teeth are formed on the stator with a predetermined spacing therebetween. The stator extends to a region outside of an effective movable range, and a braking winding is wound around the teeth in the extended portion. When the slider moves into a region outside of the effective movable range, an induced voltage is generated in the braking winding and a current flows. A thrust in a direction opposite to the movement direction of the slider is generated by the current.

摘要： A plurality of projections are provided abutted with an outer circumference of a columnar axis inserted to an inner circumference of a rotor. The projections are provided in the direction of a magnetic pole in the rotor. When the rotor is fixed to the columnar axis, the projection parts are fixed by “plunge-in” and the other rotor inner circumference parts have an uniform clearance to the columnar axis. The clearance is filled with an adhesive agent, thereby fixing the rotor to the columnar axis.

摘要： An induction motor controlling device realizes precise and discretional revolutional speed vector control without requiring a speed detector using an algorithm which is suitable for a system including a microcomputer. A three-phase-to-two-phase converter detects a torque current inside a motor as a DC quantity based on instantaneous values of motor currents. A slip frequency is estimated using the torque current, and the slip estimation is used to obtain a motor's revolutional speed. An error in revolutional speed estimation is compensated by a compensation value which is obtained by amplifying an excitation current common phase voltage command.

摘要： A control unit for an induction motor continuously provides a precise output torque without being adversely affected by a magnetic saturation of an iron core, or varying precision of sizes of components constituting the motor or varying temperature of the motor. When a torque command value T* is smaller than a predetermined value Trf, an excitation inductance M is corrected in accordance with a torque voltage command Gq.multidot..DELTA.i1q which is calculated on the basis of a torque current command i1q* and a torque current i1q. Further, a secondary resistance r2 is corrected on the basis of the torque voltage command G.multidot..DELTA.i1q. A slip frequency is calculated on the basis of the secondary resistance r2, a magnetic induction command .phi.*, and torque current command i1q*. An angular frequency command .omega. is calculated. The magnetic induction command .omega.* and the torque command T* are converted into an excitation voltage command ed* and torque voltage command eq* to be applied to the motor on the basis of the corrected excitation inductance M and the angular frequency command .omega..

摘要： The drive control apparatus for a linear actuator according to the present invention uses fine actuators, such as an electrostrictive element, so that it is possible to manufacture a linear actuator drive control apparatus obtaining big driving force in spite of a size considerably smaller than the conventional magnetic motor and linear motors utilized electromagnetic force. In addition, since the fine actuator and the driving base repeats their fixings and seperatings, it is possible to make the driven stroke range of the driving base wide. Since the fixing operation and the separating operation are carried out when the speeds of the fine actuator and of the driving base are almost the same, generation of the shock due to sudden speed change of the fine actuator and the driving base at the same of their fixing and separating is prevented, and it is possible to obtain smooth driving of the driving base. Control of the speeds of the fine actuator enables to finely and precisely control the speed of the driving base.

摘要： Coils are formed into a coil group for a single phase by serially connecting a plurality of coils so that the resulting magnetic flux distribution is a sine wave distribution. The coil group for a single phase is constituted by a plurality of coil sets, formed from two coils that are wound around two adjacent magnetic pole teeth, connected in series. Each coil set includes coils of the two magnetic pole teeth constituting that coil set wound in opposite directions to each other looking from the inside of the stator. An electrical wire extending from an end winding of each coil is turned back so as to run in a direction opposite to an electrical wire connection to a start winding of that coil, and is connected to either a start winding of the next coil or a connection terminal.

摘要： To form magnetic poles P on a rotor, a plurality of slits extending along a radial direction in a region close to the magnetic poles P and extending along a circumferential or chord direction in mid areas between the magnetic poles P are formed. The width b of circumferential slit segments extending along the circumferential or chord direction is narrower than the width a of radius slit segments extending along the radial direction. Permanent magnets are disposed in the narrowed segments of the slits to suppress leakage of magnetic flux. Thus, in a motor in which magnetic paths separated by the slits are formed on the rotor to provide regions having different magnetic reluctances in a circumferential direction of the rotor, a structure in which a through hole penetrated by an output shaft of the motor can have a large diameter is provided.
