Abstract

PURPOSE:To reduce a reaction force applied to a fixed side of the motor, where the pole part and the moving coil are displaced in an opposite direction to each other, by providing a secondary coil, for magnetically making a coupling with the moving coil, partially in the pole unit which is movably supported by a spring method. CONSTITUTION:With a magnetic pole 7 movably provided in a reverse direction to the moving direction of a moving coil 6, further with a secondary coil 8 concentrically provided with said moving coil 6, a reaction force, caused by said moving coil 6, is made a replacement by a force that moves the secondary coil 8 and the movable pole 7 made in one unit with said secondary coil 8. The secondary coil 8 and the movable pole 7 are fixed to yoke 3 by a fixing material 11 at one end through a spring 9, and supported at another end through a non-magnetic stiff ball 10, with a construction so made as to provide a smoothness of their movements. In this way, the movement of the pole unit (movable pole 7, secondary coil 8) made in an opposite direction to the moving coil 6 can provide a linear type DC motor of vibration-proof construction in which the reaction force, affected to a fixed side of the motor, is reduced.
