Measure the voltage on the volt meter. Why is a "lower" kv rating faster? I. The middle son is very interested in RC cars and is always asking me things. The speed is directly proportional to the voltage that is applied to the phases (e. Forget the slow web calculators with limited features. A brushless DC electric motor (BLDC motor or BL motor), also known as electronically commutated motor (ECM or EC motor) and synchronous DC motors, are synchronous motors powered by direct current (DC) electricity via an inverter or switching power supply which produces electricity in the form of alternating current (AC) to drive each phase of the motor via a closed loop controller. For a DC motor (which BLDC motors approximate by varying the Vin): Torque = Kt * Vin / R - Ke * Kt * n / R. For a given (say 40V) supply you can work out how the current varies as RPM, ((via the speed constant to give the back EMF, and the resistance to give the current) and hence both electrical power and mechanical power (= electric power minus loss in that resistance). Motor Business Division, Appliances Company, Panasonic Corporation 1. KV, Io & Rm Simulation Software.
