To provide a moving coil type linear motor which permits the reduction in the number of cables in a wiring harness drawn out of its mover, facilitates the installation of the wiring harness and permits the suppression of the noises effects upon electrical signals, which are outputted form a field magnet sensor and an encoder sensor which are provided on the mover, while the signals are transmitted through the wiring harness drawn out of the mover.
A linear motor consists of a stator 1 with field magnets 11 are a mover 2 with an armature coil 21 put onto the stator 1. Six coils of which the armature coil 21 is composed are connected to each other in a predetermined connection state with an electric circuit board 23 provided on the move 2. A circuit which binaries the output signal of a Hall device, which detects the pole of the field magnet 11 and a circuit which binaries the output signal of an optical sensor 41 for an encoder are provided on the board 23.
