Abstract
Abstract An electrical motor system is provided in which driver means position the motor, control the speed of the motor and control the current delivered to the windings of the motor. The operating parameters of the system are sensed on a moment by moment basis and data concerning these operating parameters is provided to a memory. A user has the ability to provide a plurality of user-stipulated operating parameters during use of the motor system. The user-stipulated operating parameters are sensed on a moment by moment basis and data concerning the user-stipulated operating parameters is provided to the memory. The memory contains limiting parameters, sensed operating parameters and user-stipulated operating parameters and a set of adaptive programs for determining the relationship between these parameters. The various parameters are fed to a computer which operates with them, via the adaptive programs, to create, on a moment by moment basis, a new set of operational limiting parameters.
