Inventor: SUDO NOBUHIRO
IPC: G01L3/22
Filed: 1992-12-25
Abstract: PURPOSE:To eliminate an expensive power converter and increase response speed by detecting the current and voltage on DC side of the power converter, alpha-axis current and q-axis current controlled by an inverter, the temperature inside an inductor, and the number of rotation of an inductor so as to calculate the torque. CONSTITUTION:The AC power from a 3-phase AC power supply 1 is converted into DC power by a converter 2a for converting power, and the output is converted into 3-phase AC power by an inverter 2b, then it is supplied to an inductor 3. The current I outputted from the converter 2a is detected by a DC current detector 4, and the voltage V by a DC voltage detector 5, the number of rotation N by a rotation frequency detector 6, the temperature t inside the inductor 3 by a temperature detector, respectively. In addition, the q-axis current Iq and d-axis current Id of the inverter 2b are detected. After the detected values are inputted into a torque operation device 9, the motor inputs are substracted by a copper loss and stray load loss and then is divided by the number of rotation N to obtain an output axis torque T. Thus, the AC power is converted into DC to obtain the electric power, resulting in high-speed response and high-speed controlling.
