The RPM of the engine.
18000 RPM
It's usually measured in RPM - Revolutions-Per-Minute, counted at the crankshaft.
Frequency is a function of engine speed and the number of poles in the generator end. For instance, a speed of 1500 RPM turning a four-pole generator will produce 50 hz. The formula is: Frequency = (poles/2) * (RPM/60) From the formula, you can see that the same frequency would be produced by a two-pole generator spinning at 3000 RPM.
100-350 rpm
A typical idle speed for a normal car engine is 600 rpm to 1,000 rpm. It is higher for buses and motorcycles. RPM stands for revolutions per minute.
Horse power calculations consider several variables, but for rotational engines, the formula is (torque x speed)/5252; Where torque is in lbft and speed is rpm. For the 242 series engine with an estimated 8.5 compression ratio, the engine is 10HP.
crankshaft rpm (revolutions per minute)
engine speed (rpm) road speed (mph)
To calculate the speed of an induction motor use the following formula, RPM = Hz x 60 x 2/motor # of poles. To answer the question, most of the motors must have 4 poles.
