Abstract :
The unbalanced reciprocation force due to armature reaction field decreases the advantage of the moving coil linear motor, such as a high degree of linearity and controllability in the force and motion control. This paper first describes the coil inductance, the deviation of flux density, and the unbalanced force, which are derived from the permeance model of the motor. Secondly, the dynamic simulation algorithm considering the armature reaction effect and variable inductance is proposed. Thirdly, the control algorithm is proposed to reciprocate a load without mechanical spring at the required stroke and position. Finally, the validity of the proposed algorithm is confirmed by experiments
