Here, the movable element 723 is connected to the core 41 of the stator 40.
The plurality of irregularities 411 provided at the tips of the comb teeth are formed in a 4t[a shape] with a pitch slightly different from that of the pitch.

Next, the operation of such a one-ship speed truck will be explained above.

■ It is assumed that the transport vehicle initially stops at station 51 and moves to station C.

(2) It is assumed that the transport vehicle receives a command from a separate computer to go to stations S2 and S3 and stop there.

■ The commands from the computer are input to a separate controller,
The stator 40 at station S1 is sequentially excited based on signals from the controller, and the first narrowing cart moves in the direction.

■ The transport vehicle reaches station S2 and stops at station S2.

■ After finishing work at station S2, return to station S.
The stator 40 at position 2 is energized to start the transport vehicle, and the 1-ship speed vehicle reaches the 1-ship transport vehicle direction changing section 80.

(1) When the carriage reaches the carriage direction changing section 80, the stop/start stator 84 is sequentially energized based on instructions from the computer until the carriage comes to a preset position.

(2) The transport vehicle is temporarily stopped at the transport vehicle direction changing section 80.

■ Crank rod 831 is fixed by a button (not shown).

That is, at this time, the 1-speed bogie will transfer to the lane on the near side (the lane including stations S3 and S4) shown in FIG.

[Phase] The stop/start stator 84 is sequentially energized based on instructions from the computer to start the IM trolley.
The insertion rod 832 comes out of the rod insertion hole 711 at the same time as the IM carriage starts moving. Then crank rod 8
31 makes a 180 degree reverse rotation and returns to its original position until the next transport vehicle arrives.

■ The transport vehicle reaches stage gin S3 and stops there.

Further, the operation of the conveyance vehicle direction changing section 80' is completely similar to that of the conveyance vehicle direction changing section 80.

Although the above description has been made assuming that the direction of the magnetic flux generated from the stator is perpendicular, the present invention is not limited to this. For example, as shown in FIG. 4 as another embodiment,
The main running rail 50 is made slightly wider than that shown in FIG. This also includes a case where the movable element is included in the driving body.
