When selecting a Coreless Brush DC Motor for an application, or when developing a powered prototype, there are several basic motor physics principles which must be considered to produce a safe, well-functioning, sufficiently-powered precision drive system. In this document, we have provided some important methods, formulas and calculation details to determine the power output of a coreless motor, the speed-torque curve of the motor, the current and efficiency plots, and the theoretical cold calculations that estimate motor performance.
