Synchronous reluctance tubular linear motor for high precision applications

This paper presents a novel Synchronous Reluctance Tubular Linear Motor (SyncRTLM) for high precision motion control applications, such as machine tools. Finite Element Analysis (FEA) of the motor is conducted to simulate the motor performance and to analyse the magnetic fields in the motor. The design and development of the built motor is outlined, where a novel construction technique is described. The position, velocity and force performance is measured using a modified servo current control algorithm.
