摘要： During synchronous control, a first servo motor controls a position of a first spindle system and a second spindle system having a second servo motor makes calculations for estimating the torque required for the second servo motor and gives a command, so that, when a rotational phase difference between the two servo motors exceeds a predetermined value, the rotational phase difference is made equal to zero by a rotational phase difference signal. A torque command to the first servo motor, an inertia ratio between the first and second servo motors, the rotational resistance of the two spindle systems and so on are input to a torque estimator which makes calculations for estimating the torque required for the second servo motor. The estimated torque is used to control the second servo motor. The two servo motors thus generate the appropriate torque when a work held between the two spindle systems is processed. It is therefore possible to significantly reduce the torsional torque applied to the work. In addition, since the rotational phase difference between the two servo motors of two spindle systems is reduced, synchronous control with high precision can be effected even if the work has a low rigidity.

摘要： A motor is provided, which has a larger torque and a high power factor in lower rotation speeds and a high power factor and a field weakened characteristic in a higher rotation speed range. The motor is provided with a long-hole shaped slit arranged between a rotor magnetic pole and a further rotor magnetic pole located adjacently to the rotor magnetic pole in a circumferential direction, a permanent magnet arranged in the slit, and a non-magnetic member arranged closely to the permanent magnet in a direction of magnetic fluxes. For large torque, this configuration reduces variations in rotor field magnetic fluxes, due to torque current components. In the rotation speeds, magnetic fluxes from the permanent magnet is suppressed from causing excessive field magnetic fluxes, which balances larger torque with higher power factors and a field weakened characteristic with higher power factors.

摘要： A torque generator includes a full-pitch winding reluctance motor provided with three-phase or more coils which are composed of full-pitch windings, and a control unit therefor. The control unit controls currents supplied to the respective phase coils such that the coil for a first phase designated among the phases is first started to be current-supplied and then the coil for a second phase designated among the phases is started to be current-supplied during the current supply to the coil for the first phase. The control unit decreases an amount of the current supplied to the first coil immediately before starting the current supply to the second coil and to reinstate the amount of the current supplied to the first coil in response to starting the current supply to the second coil.

摘要： A motor controller includes a power source VG for driving a motor 1, a power source VRG for regenerating energy generated in the motor 1, and a power converter for transferring energy from the power source VRG to the power source VG. Windings of the motor are connected, at their opposite ends, to the power source VG and collectors of transistors TR1 to TR3, respectively. Diodes D1 to D3 are connected to nodes of the windings and the transistors TR1-TR3 such that magnetic energy generated in the motor 1 is supplied to the power source VRG. This configuration enables the motor controller to have a reduced number of transistors for driving the windings, and the power sources to be effectively utilized. Further, the motor controller can use a discharge circuit of small power consumption type, which can reduce heat generated in the motor controller.

The braking device further includes a compression spring coupled to the braking member for exerting a force on the braking member to cause the braking member to contact a rotating member of the rotary motor. The braking device further includes a piezoelectric element for actuating in response to a signal applied thereto to exert a force on the braking member to counteract the force applied to the braking member by the compression spring so as to cause the braking member to separate from the rotating member of the rotary motor.
