Title: Open-phase detector for ac servo device
Inventor: HOSHINO AKIHIRO
IPC: H02P21/22
Filed: 1989-03-22
Abstract: PURPOSE:To trip a servo unit by adding three-phase current detection signals of an AC three-phase motor then producing an open-phase detection signal based on the added value, CONSTITUTION:A three-phase current detection circuit 8 receives outputs from current sensors and produces actual three-phase current detection signals. An operating circuit 10 receives the actual three-phase detection signals which are then added to produce an added three-phase current. An absolute circuit 11 receives the added value and makes the absolute value thereof thus producing an absolute value signal. An open-phase signal output circuit 12 receives the absolute value signal, and when its value exceeds over a threshold an open-phase detection signal indicating occurrence of open-phase condition is produced. Since the open-phase detection signal indicates occurrence of open-phase condition in a three-phase AC motor, power supply for the motor is tripped.

Filed: 1994-03-15
Abstract: PURPOSE:To simplify the structure, reduce the cost and make assembly and adjustment easy by outputting a signal according to transmission torque with a change with time in electromagnetic variable as a reference. CONSTITUTION:A twist of a torsion bar 8 according to a change in transmission torque from an input axis 3 to an output axis 4 causes a first detection ring 13 and a second detection ring 14 to relatively rotate with the same axis as the center. Since areas in parts overlapping with respect to an axial direction of teeth 13a, 14a formed on respective opposite end faces of the rings 13, 14 change, magnetic resistance of a torque detecting magnetic circuit changes, whereby output voltage of a detection coil 17 changes due to a change in impedance according to the change in magnetic resistance. In addition, since the output voltage of the coil 17 changes according to a change in surrounding temperature, the change in impedance of the coil 17 in the torque detecting magnetic circuit depends on the change in transmission torque and the change in temperature.
