<p>PURPOSE:To facilitate the mounting even at a small space while enabling stable torque detection with a high output and a high S/N ratio, by combining differential outputs from detection windings applied on respective detection magnetic core couples. CONSTITUTION:Excitation windings 411 and 422 of first detection magnetic core couples 31 and 32 are connected cumulatively while detection windings 412 and 422 thereof are connected differentially. Likewise, excitation windings 431 and 441 of second detection magnetic core couples 33 and 34 are connected cumulatively while detection windings 432 and 442 thereof are connected differentially. The excitation windings 411 and 421 of the first detection magnetic core couples 31 and 32 and the excitation windings 431 and 441 of the second detection magnetic core couples 33 and 34 are connected in parallel and introduced to an AC power source 45. On the other hand, the detection windings 412 and 422 of the first detection magnetic core couples 31 and 32 and the detection windings 432 and 442 of the second detection magnetic core couples 33 and 34 are connected in series and Vout outputted is detected as torque output via an electric circuit.</p> |
