To measure the Ke of the motor, put the motor shaft in a lathe and rotate the shaft at some speed [rpm] such as 1000rpm. With a dc motor, use a dc voltmeter to measure the armature voltage. The Ke is then the voltage you read divided by the speed in rad/sec. Convert rpm to rad/sec as- = 60sec sec 2 min min rad x rev radians x rev π [ ] Aug 18, 2005 · After that, it calculates the average motor RPM in your fastest lap(=60000*(speed in m/s)/(mm per motor rotation)) (*60000 because *1000 for mm->m and *60 for minute->second). Then, it indicates the gear ratio that would lead to an optimal RPM (max/2). (=(maxRPM/2)*pi*diameter/(60000*(speed in m/s)) Feb 09, 2009 · For an RPM of 60 and a speed of 0.5 m/s (18"/s), r0 works out to 0.08m, about 3 inches. Under no load the motors will run at 60 RPM, so the bot will move at the desired speed. Under load -- going uphill for example -- the motors will run slower and we'll need larger wheels, although it will stall when we hit r1.
ACCELERATION TORQUE CALCULATION: When a machine must be accelerated to a given speed in a certain amount of time, the drive system HP may have to supply additional torque during acceleration to compensate for the load inertia.

Using the above calculations, if the water wheel is 2m high, the required flow rate to make 60 horsepower is 2,280 liters per second, or 602 gallons/second. (assuming 100% efficiency, of course, I neglected efficiency in the initial calculation because I didn't want to be TOO obnoxious) Keep in mind that 60 hp is a lot of power. The Kv rating of a brushless motor is the ratio of the motor’s unloaded RPM to the peak (not RMS) voltage on the wires connected to the coils (the back EMF). For example, an unloaded motor of Kv, 5,700 rpm/V, supplied with 11.1 V, will run at a nominal 63,270 rpm (5,700 rpm/V × 11.1 V). Motor Torque constant
In Metric System the H.P is ( 2 X (phi or 3.14) x N x T )/4500 where N is speed in RPM and T is Torque in Kg.M. If you derive the above equation from fundamentals, you will get the constant 33,000 for FPS system and 4500 in Metric System.
