摘要： PROBLEM TO BE SOLVED: To detect the displacement without using a displacement sensor, and also, to make a position control part and a motor control part to be independent by detecting the rotating magnetic field in a bearing-less rotary machine. SOLUTION: Rotor displacement and the rotating magnetic field are simultaneously detected by newly forming an additional coil and by applying a high frequency voltage. In this way, the rotor displacement and the rotation magnetic field can be simultaneously detected from the additional coil. Reduction in costs, miniaturization, and critical velocity can be improved, and at the same time, a multi-purpose inverter and a commercial power supply can be used on the motor side.

摘要： The driving module controls the supply of current to a shape memory alloy member by setting a command value for an electrical resistance of the shape memory alloy member so that the lens frame is moved intermittently to thereby controlling the driving of driving means. The driving module includes control means which includes resistance detection means, command value generation means, and current supplying means. The command value generation means changes the command value gradually by a predetermined variation width ΔR so that the electrical resistance of the shape memory alloy member increases or decreases gradually by a predetermined width when the lens frame is moved intermittently. Moreover, the command value generation means performs a correction calculation which uses the ratio of an actual reference value R0 of the electrical resistance of the shape memory alloy member to an ideal reference value Rstan of the electrical resistance of the shape memory alloy member as a correction ratio to calculate a correction variation width by multiplying the correction ratio by an ideal variation width Rstep of the command value Rt(n) to thereby change the command value Rt(n) gradually using the correction variation width as the variation width ΔR.

摘要： An electric motor has a rotor having an end portion and a recessed portion formed at the end portion. A rotational shaft is mounted to the rotor. A stator covers an outer peripheral portion of the rotor and forms a magnetic field that generates a torque around the rotational shaft to thereby rotate the rotational shaft and the rotor. A bearing rotatably supports the rotational shaft and is entirely spaced-apart from the end portion of the rotor in an axial direction of the rotational shaft. A slider is slidably mounted around the rotational shaft and supports rotation of the rotational shaft about a rotational axis thereof. The slider is interposed between the bearing and the rotor so that a portion of the slider is entirely contained in the recessed portion of the rotor and the remaining portion of the slider is disposed in the space between the bearing and the rotor and in contact with the bearing.
