WebAnother consequence of higher voltage is related to the way brushless DC motors work. Every motor has a Kv rating. The Kv tells you how many RPM you get per 1V of input. So a motor with a Kv of 10 would spin (without any load) 360 RPM at 36V, 480 RPM at 48V, and 720 RPM at 72V. This is called nominal RPM. WebChapter 4 Ex and problem solution. advertisement. Exercise 4–1 Ex: 4.1 Refer to Fig. 4.3 (a). For v I ≥ 0, the diode conducts and presents a zero voltage drop. Thus v O = v I . For v I < 0, the diode is cut off, zero current ﬂows through R, and v O = 0. The result is the transfer characteristic in Fig. E4.1.
