Abstract: An optical measurement probe is a probe for guiding light generated from a measurement target to an appliance, and includes an optical window and an optical fiber. The optical window is formed in a columnar shape, one of end surfaces of which forms a reflection surface (tapered surface), the optical window transmitting light entering from an incident surface (flat surface) formed on a portion of an outer peripheral surface of the optical window, causing the light to be reflected by the reflection surface, and emitting the light from the other end surface. The optical fiber guides the light emitted from the other end surface of the optical window to the appliance.

Abstract: When sub-field magnets 8a and 8b are not provided, the magnetic fluxes that pass through main field magnets 7a and 7b respectively and interlink with stator windings 5 and first rotor windings 6, and the magnetic fluxes that pass through the main field magnets 7a and 7b respectively and short-circuit adjacent main field magnets 7b? and 7a? are generated. The short-circuited magnetic fluxes do not contribute to torque generation, therefore a favorable inner periphery magnetic circuit is not formed, and the torque received between a second rotor 4 and a first rotor 3 becomes small. When sub-field magnets 8a and 8b are provided, on the other hand, the short-circuited magnet fluxes interlink with the first rotor windings 6 by the sub-field magnets 8a and 8b, and an inner periphery magnetic circuit is formed, whereby the motor driving torque received between the second rotor 4 and the first rotor 3 increases.
