Design and Testing Servomotor Prototype ☆

This paper proposes an optimal design “modern” approach for servomotors. This approach consists of using the optimization algorithms at the initial analytical calculations, in combination with the modelling of the virtual prototype in order to reduce the costly and time-consuming prototyping loops of the “conventional” design method. The optimal design of a servomotor for robot application is verified using finite element analysis (FEA) in term of torque at low to high speeds. The thermal simulations based on lumped-mass model have been conducted in order to determine the operating duration of maximum and continuous performances of this machine. A prototype of asynchronous servomotor is manufactured and tested in the test-bench. Experimental results of electromagnetic (torque) and thermal (rising temperatures of different positions in the motor) measurements of peak and continuous performances at different speeds will validate the virtual prototype as well as this design method.
