PURPOSE:To improve the efficiency of a linear pulse motor and to obtain a stable thrust by maintaining a gap between the primary side magnetic core projection and the secondary side projection constant and providing poles at both right and left sides of the primary side core. CONSTITUTION:Four winding cores are formed at both upper and lower sides and left and right sides of the primary side magnetic core 1, and windings 12 are wound. When exciting currents are simultaneously flowed through the windings 12, magnetic flux is generated at the primary side magnetic core projection 11. Thus, attracting force is acted on the projection of the secondary side part 2 opposed at the prescribed interval to the projection 11, and thrust is generated so that the both projections tend to be superposed to each other. Continuous thrust is obtained by sequantially switching the exciting of the primary side core 1 by utilizing it, thereby traveling a carriage truck 7, to which the secondary side 2 is secured, along guide rails 8. |
