| Abstract |
A new servomotor has been optimized to replace a existing servomotor in an industrial robot. The material cost of a machine, which is able to perform a specific task, is minimized. The optimization routine utilizes information about the drive-cycle and the load is thereby able to include the inertia of the machine in the optimization. The finite element method is used to optimize the magnet geometry. The result is a machine design with has a 35% shorter stator, 50% lower inertia (active part) and a 41% reduction in material cost as compared to its predecessor. A prototype has been built. Initial test results indicates that the prototype has the predicted torque constant, but can only produce 94% of the desired torque at 100°C average temperature rise in the windings. |
