Title: Position detecting method of linear motor
Inventor: KANAZAWA HIROYUKI
IPC: H02P25/06
Filed: 1985-01-14
Abstract: PURPOSE:to accurately detect the position by synchronizing and outputting the output signal of a trailing position sensor with that of a preceding position sensor. CONSTITUTION:When an encoder (not shown) generates an output signal A2, the value of a signal A2 of the falling time of a waveform shaping signal S1 is stored in a latch circuit LC1, and the value of a signal A2 of the rising time is stored in a latch circuit LC2. Comparators CO1, CO2 compare the outputs of latch circuits LC1, LC2 with the signal A2, and apply signals V1, V2 to an EOR circuit. The output of a flip-flop FF is inverted by the rise of the output EO of the EOR circuit to obtain a signal S2''. A selector SELEC switches input signals S1, S2'' by a select signal SS.

Abstract: PURPOSE:To accurately control the position of a pen by providing a memory storing the output value of a function converter circuit when the characteristic of a position detector is a planned characteristic and the output value thereof when the output of the position detector is inputted with respect to two mutually different points of a relative position and correcting the output of the function converter circuit on the basis of the data read from the memory. CONSTITUTION:The numerical values n1s, n2s on a straight line B to two mutually different points z1, z2 within a relative position (z) and the numerical values n1, n2 on a straight line A are stored in a memory 34. The numerical values n1s, n2s are determined by planning and constant but the numerical values n1, n2 are respectively different according to position detectors 4 and measured every time. When the output (n) of a function converter circuit 32 is obtained with respect to the combined position detectors 4, the output (n) corresponds to the relative position (z) and must be an accurate numerical value ns and, therefore, a correction circuit 33 calculates ns from (n) according to formula 1 to input the same to a control part 30. As a result, the accurate numerical value ns showing (z) is given to the control part 30 and a position can be accurately controlled on the basis of the value ns.
