Abstract
Linear motor performance under large cutting forces at varying air-gap sizes and voltages is investigated. Under certain loading conditions, electromagnetic, thermal, and static analysis of the secondary elements is determined using EMRC-NISA software. Electric and magnetic field distribution is also determined for generated force by varying voltages and gap sizes. Due to the presence of conduction currents in electromechanical devices such as permanent magnet brushless DC linear motors (PMBDCLM), power losses in the form of heat dissipation are produced which alters the temperature distribution in the device. Change in temperature effects the generated force, electric and magnetic fields, thus overall performance. In this paper, single-sided linear motor geometry is presented. An overall rating based on performance and cost is determined. Post processing is performed in conjunction with steady current flow analysis, magnetic field analysis, electric field analysis, electromagnetic sub-analysis, and static analysis. A case study and result implications are also discussed.
