A rotor position detection apparatus (Y) is applied to a SR motor (10) including a stator (12) having salient poles (11a-11c) corresponding to a plurality of phases, each salient pole (11a-11c) having excitation windings (15a-15c), and a rotor (14) disposed in the stator (12) and provided with a plurality of salient poles (13). A magnetic flux detection means (X) is provided with a detection part in a position where a magnetic flux generated by a phase current in the stator (12) is detected. The apparatus (Y) includes a threshold value holding unit (21) holding the magnetic flux detected by the detection part as a threshold value, when the rotor (14) is located at a predetermined detection position; and a comparison unit (25) comparing a threshold value with the magnetic flux, wherein the apparatus (Y) detects that the rotor (14) has reached a predetermined position, based on the comparison result of the unit (25).

The rotor position detection apparatus Y is applied to an SR motor 10 comprising a stator 12 which is provided with salient poles 11 (11a, 11b, 11c) corresponding to a plurality of phases, each salient pole 11 (11a, 11b, 11c) provided with an excitation winding 15a, 15b, 15c and a rotor which is disposed in the stator and provided with a plurality of salient poles 13. The rotor position detection apparatus comprises a micro constant current application unit (circuit) 23 which applies a micro constant current to the excitation winding, and a polarity inversion detection means X which detects polarity inversion of a magnetic flux appearing in the stator 12 of the SR motor 10, thereby detecting a salient pole opposed position through a magnetic flux polarity inversion position.


The present invention aims to provide a non-contact power supply device capable of dissipating heat generated in a feed line as a loss, even if the feed line is arranged inside the closed container. The non-contact power supply device is used in a processing apparatus including a moving unit movable inside the closed container and the non-contact power supply device capable of supplying electric power to the moving unit from outside the closed container. The non-contact power supply device includes a feed unit and a heat dissipator, the feed unit includes a feed line and a power supply transformer, the feed line has a feed region arranged inside the closed container along the moving direction of the moving unit, the power supply transformer is arranged inside the closed container so as to be opposed to the feed region in a non-contact manner and is provided so as to move together with the moving unit, and the heat dissipator includes a portion on one end side connected to the feed region so as to be capable of conducting heat thereto and a portion on the other end side extending outside the closed container, so that heat generated in the feed region is partially dissipated outside the closed container.

Multipliers 21a and 21b output values, which are obtained by multiplying a total drive command value E_(s) by first and second gains G_(1) and G_(2), respectively, as first and second drive command values E_(1) and E_(2). Controllers 23a and 23b control first and second actuators (motors) 5 and 7, respectively, on the basis of the first and second drive command values. The detection values of the drive amounts of the actuators are denoted by E_(f1) and E_(f2), respectively, and the detection value of the drive amount of a driven body is denoted by E_(f). A gain calculator 27 calculates the gains G_(1) and G_(2) on the basis of E_(f1), E_(f) and E_(f2). An upper limit value of E_(f), which denotes the drive amount of the driven body, is denoted by L_(max). When E_(f1), E_(f2) or E_(f) approaches zero, the first gain G_(1) is brought close to (E_(f1) - L_(max)/2)/(E_(f) - L_(max)).
