Motor Selection Tips: Understanding Thermal Parameters of DC Coreless Motors
With the help of simple thermal modeling
When trying to understand the phenomenon of heating of coreless dc motors, its helpful to express it as a simple thermal model and to draw an analogy with an electrical system. Looking at Fig. 1, you can see the power dissipated (heat) is the difference between electrical input power and the mechanical power (speed & torque) generated by motor shaft. With this basic understanding , let’s next examine the thermal model of a DC coreless motor.
