Abstract

The common problem with linear motors is the heat production which limits the performance and reduce the accuracy of the motor. In this research, temperature behaviour of Flat Type Linear Motor Carrier is simulated and verified with actual temperature measurements, and the accuracy of the applied methodology is evaluated. Simulation consists of two parts: (1) Estimation of power losses in heat generation, and (2) steady state heat transfer analysis at estimated power losses. Electric power losses are calculated based on the power loss equations, given in motor documentation. Heat transfer analysis is carried out with calculated power losses, at moderate convection coefficient of the air. Simulations and experimental evaluation prove that temperature behaviour of the linear motor carrier can be estimated precisely using this methodology.
