Abstract

See full text

A motive system for a patient lifting assembly, a patient lifting assembly and a method of operating a patient lifting assembly. The motive system includes an electric motor, numerous sensors and an adaptive control unit cooperative with one another so that a memory and processor that are part of the control unit that can respectively store and execute a computer readable and executable instruction set. By comparing collected data from the sensors during operation of the motor to corresponding reference values associated with one or more motor operational parameters—such as accumulated motor wear over time or differences in operating temperature of the motor—the system can selectively adjust the maximum amount of current available for use by the motor. In this way, changes in motor efficiencies that arise with these parametric changes can be taken into consideration when determining an upper limit on how much electrical current may be delivered to the motor for a given load.
