The transmission error characteristics of a stepping motor drive timing belt system are investigated theoretically and experimentally for the fixed and the automatic tensioner. It is found that the amplitude of the transmission error θe due to the pulley eccentricity and θm due to the stepping motor torque variation decrease as the belt tension increases and the applied torque load increases. Also, θe can be reduced by using the automatic tensioner, while θm shows almost same magnitude for both tensioners. The theoretical results based on the bondgraph model are in good accordance with the experimental results.
