PROBLEM TO BE SOLVED: To provide a technique for more effectively using magnetic flux in a coreless brushless motor.SOLUTION: A coreless brushless motor includes a first structure part 10 and a second structure part 30. The first structure part 10 includes at least one pair of coil rows 12 having a plurality of electromagnetic coils in which conductive wires are individually wound into a ring shape without having a magnetic core. The first structure part 10 functions as a stator or a movable body. The second structure part 30 includes a magnet row 32 having a plurality of permanent magnets. The relative position of the second structure part 30 to the first structure part 10 can be changed. The coil row 12 includes a magnetic yoke member 18. The magnetic yoke member 18 is disposed on the opposite side of the magnetic row 32 across the coil row 12. |
