An electronically commutated brushless motor including a motor housing, a bulge formed in a sidewall of the motor housing, and a capacitor assembly housed in the bulge. The capacitor assembly includes a capacitor printed circuit board (PCB) having a plurality of longitudinal edges and at least one capacitor mounted on the capacitor PCB. The bulge includes a plurality of channels located along an inside surface of a sidewall of the bulge, in which the longitudinal edges of the capacitor assembly are slideably inserted.

The method according to claim 11, wherein the resistance of the coil is determined by dividing voltage across the coil by a voltage drop across a sense resistor which is proportional to current through the coil. 13. The method according to claim 12, wherein the coil resistance is determined when the time derivative of flux is zero and the drive coil current is not zero. 14. The method according to claim 11, wherein the resistance of the coil is approximately by subtracting voltage across the coil from a voltage which is proportional to the current through the coil. 15. The method to claim 14, wherein the coil resistance is determined when the time derivative of flux is zero and the drive coil current is not zero.
