PURPOSE:To simplify the positioning system by transmitting a speed command and a travel distance command signal from the ground side to an induction line laid on stationary secondary conductor and controlling the movement of the primary conductor, thereby enabling to position at the linear motor itselt. CONSTITUTION:A command controller 1, a modulator 2 and an induction line 4 laid along rails are provided on the ground side, and an antenna unit 6, a demodulator 7 and travelling distance and speed controllers 8, 9 are carried on a drive motor 11. The modulated command signal is outputted to the line 4, picked up by the antenna unit 6, demodulated, the signals of the speed detector 2 and the position detector 13 are fed back, thereby controlling the speed and the position. Accordingly, the position and the speed can be controlled by the linear motor itself merely by applying the command from the ground side. In this manner, the system can be simplified by eliminating the positioning mechanism on the rails. |
