Design optimization for minimizing cogging torque in Axial Flux Permanent Magnet machines

2017 International Conference on Optimization of Electrical and Electronic Equipment (OPTIM) & 2017 Intl Aegean Conference on Electrical Machines and Power Electronics (ACEMP), 2017
This paper deals with the optimization of a single side Axial Flux Permanent Magnet machine (AFPMM) designs with respect to cogging torque. Although the AFPMMs run generally at high speed and high torque, these machines may run at lower operational speed for aircraft applications. At lower operational speed, the cogging torque is an undesirable effect.

Liquid Crystal Elastomer Actuator Matrix for Large Area Applications

Advanced Materials Technologies, EarlyView.
A scalable approach is used to manufacture a digitally‐controllable, 2D 5 × 5 actuator matrix. The elements of the matrix are produced by direct ink writing of a liquid crystal elastomer ‘artificial muscle’ on large‐area flexible thin‐film heaters. In optimizing the low‐power actuators, multiple heater designs and substrate materials are investigated ...
