Some Considerations on the Directional Control of a Linear Parametric Motor

Abstract

This paper describes two methods for the directional control of a linear parametric motor. The first uses a circuit-changing switch. The direction of this linear parametric motor can be controlled by exchanging the power supply circuit and tuning the capacitor circuit. In the second method, which we call the separately excited type, the linear motor has two power supplies, and the velocity or direction of the moving part can be easily controlled by regulation of the primary voltage phase difference.
The experimentally as certained features of these methods are described.
