Abstract
This study investigates the experimental validation of transverse flux linear motors (TFLMs) with permanent magnet excitation and the dynamic simulation of the developed TFLM created using the optimal design. Our research challenge is to use the developed direct drive TFLM to substitute the rack and pinion in a rotary motor because the rack and pinion lacks speed and thrust. The electromagnetic field characteristics are calculated using 3D finite element method analyses, and the dynamic characteristics are simulated using mechanical balance equations. After calculating the integral parameters, the dynamic behavior of the machine is simulated. The Matlab/Simulink model for solving motion equations is used. The peak currents obtained from simulations and experiments are very closely matched within 1%, which is the estimation error. The structural stability is evaluated using structural analyses that consider the load and moment of a robot. In order to reduce the structure-borne noise radiated from the main driving frame, damping materials are applied and the sound pressure level decreases by approximately 8.5 dB(A). Finally, the repetitive position accuracy is considered and measured using an API laser tracker T3. The measured repetitive position accuracy is within 0.1 mm at a speed of 3 m/s.
