Last year’s 2017 JMAG User Conference saw the presentation of “Application Studies of the JMAG Optimization Function in the Design of Wristwatch Motors”. The JMAG optimization function used involves optimization calculations carried out via an extension of parametric analysis chosen as a standard JMAG feature with the study of the application of a genetic algorithm. The challenge this year was therefore the optimization of topology with a higher degree of geometric freedom compared to parametric optimization, with the added possibility of reducing designer preconceptions and prior mindsets towards design. This similarly reports on the application studies of JMAG topology optimization in the design of wristwatch motors.
