Angular oscillatory single-stroke electromagnetic vibratory motor with a semiconductor element

Abstract

The paper discusses the design, operating principle, and functional capabilities of an angular oscillatory single-stroke electromagnetic vibratory motor controlled by a semiconductor element. The vibratory motor consists of a salient-pole stator and an armature with an equal number of uniformly distributed poles. Alternating current windings are placed on the stator poles and connected either in series or in parallel. A semiconductor element is connected between one terminal of the winding and the power supply source, ensuring current flow only during one half-cycle.

The developed design ensures the simultaneous participation of all pole pairs in torque generation, reduces shaft radial oscillations and undesirable leakage magnetic fluxes, simplifies the manufacturing process, and improves the energy, mechanical, and operational characteristics of the vibratory motor
