DC Motor Frequency given Speed Solution

STEP 0: Pre-Calculation Summary

Formula Used

Frequency = (Number of Poles*Motor Speed)/120
f = (n*N)/120
This formula uses 3 Variables

Variables Used

Frequency - (Measured in Hertz) - Frequency is the number of occurrences of a repeating event per unit of time for an electrical signal.
Number of Poles - Number of Poles is defined as the number of poles in an electrical machine for the flux generation.
Motor Speed - (Measured in Radian per Second) - Motor Speed is the speed of the rotor(motor).

STEP 1: Convert Input(s) to Base Unit

Number of Poles: 4 --> No Conversion Required
Motor Speed: 1290 Revolution per Minute --> 135.088484097482 Radian per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f = (n*N)/120 --> (4*135.088484097482)/120

Evaluating ... ...

f = 4.50294946991607

STEP 3: Convert Result to Output's Unit

4.50294946991607 Hertz --> No Conversion Required

FINAL ANSWER

4.50294946991607 ≈ 4.502949 Hertz <-- Frequency

(Calculation completed in 00.020 seconds)
