摘要： In order to provide a driving device for a motor having a capability equivalent to conventional vector control type sensorless method by simplifying the controls structure to reduce number of parts to be adjusted, and to stabilize the control system, a driving device for a synchronous motor does not include a speed controller or a current controller, and calculates a voltage impressed on a motor on coordinate axes (dc/qc axes) based on a magnetic pole axis. For calculating a voltage command, command values such as a rotation speed command and a current command are used, and Iq* corresponding to a torque current command is calculated and provided based on a detected current value.

摘要： A comparator, having an offset of 0.1V, compares a terminal voltage Vin1 with a clamp voltage VCL (5.1V). When an overvoltage input exceeding the VCL is entered to an input terminal, the comparator turns on a transistor Q11. The current flows across an externally provided resistor R11, the input terminal, and the transistor Q11, and flows into an output terminal of an operational amplifier. With a voltage drop at the resistor R11, the terminal voltage Vin1 starts decreasing toward an output voltage Vc of the operational amplifier.

摘要： The present invention provides a control algorithm which instantaneously detects magnetic pole positions in the inside of a motor including polarities of the motor. A controller 1 applies a minute voltage change vhd to a voltage command on a dc axis which constitutes an estimation magnetic pole axis of the motor 3, detects electric currents Idc, Iqc of a motor 3 and discriminates the polarities of the magnetic pole axes by making use of the difference between a cycle in which ripple components of the electric currents Idc, Iqc become positive and a cycle in which the ripple components become negative or the difference between positive-side and negative-side current change rates. Further, the minute voltage change vhd with respect to the above-mentioned voltage command is generated on both of the dc axis and the qc axis rectangular thereto, and the magnetic pole positions of the motor are directly estimated based on the current ripple components on the respective axes. Without separately providing a cycle for discriminating the polarities of the magnetic poles, the cycle from the turning-on of a power source to the starting of the motor can be shortened so that the high-speed starting of the motor can be realized.
