Abstract
The problem of maximizing the output torque of a step motor while satisfying power dissipation constraints is considered. Also, the optimal current which maximizes the output torque is derived. Several suboptimal controls are compared to the optimal one and their relative efficiency is evaluated. It is shown that the most common control mode is the least efficient from this viewpoint.
