摘要： A method for driving a servo-motor detects a power voltage of a servo-motor determine a detected value. Through numeric calculation, the detected value is used to control a voltage command to a power converter, where the power converter supplies the proper currents to the servo-motor. The method does not require the use of a feedback loop, and thus, requires fewer components than the traditional method that also requires the use of a current sensor and an A/D converter.

摘要： A hybrid stepping motor according to the present invention has coils wound on stator yokes arranged on a fixed shaft or coils arranged on the inner peripheral surface of stator yokes. For this reason, the coils can be easily formed, a coil mounting density higher than that by a conventional technique can be obtained, and cost reduction can be obtained. An auxiliary magnetic plate and an auxiliary magnet are arranged on both the sides of a stator yoke member to form magnetic circuits at both the ends of the stator yoke member. Therefore, motors having various numbers of phases can be obtained, and a core are partially or entirely constituted by a non-layered structure, thereby improving torque/current characteristics.

摘要： A code plate has an m-bit signal track read out in parallel for providing the starting position of an AC servo motor for commencing rotation when power is first turned ON. An n-bit signal track accompanied by an incremental signal track is provided on the code plate with the n-bit track read out serially, converted to pure binary in parallel, and used once rotation of the servo motor commences to provide the initial absolute value of the encoder. To this n-bit initial value is added signals from the incremental track upon continued rotation of the code plate.

摘要： The invention provides a servo motor encoder in which signals are output via signal lines and output terminals which are used in common. Incremental signals A, B, and Z and servo motor magnetic pole position detection signals UE, VE, and WE are switched by a multiplexer so as to output these signals via a common line driver. Alternatively, two line drivers are selectively activated and inactivated so that incremental signals and servo motor magnetic pole position detection signals are output via common signal lines. In any modes, signals can be carried via a less number of signal lines.
