DC Motor control based on motor temperature

摘要

A method of controlling a DC motor (22) is presented. In a determining action (58), a thermal power dissipation is determined from a motor input (28) and a motor velocity (32). In another determining action (60), a motor temperature is determined based on a thermal model (FIG. 4) using the thermal power dissipation. In an adjusting action (62), a usage of the motor (22) is adjusted, taking the motor temperature into account. <IMAGE>
