What is Slip in an Induction Motor? Definition, Equation & Practical Applications
speed formula of induction motor
Ever wondered why standard AC induction motors run at 1440 RPM or 2880 RPM instead of an even 1500 or 3000? ⚡🔄 The rotational speed of an AC induction motor depends entirely on two factors: the line frequency of the power supply and the number of magnetic poles wound into the stator. The Golden Formulas: Synchronous Speed (RPM): \text{RPM} = \frac{120 \times f}{\text{POLES}} Number of Poles: \text{POLES} = \frac{120 \times f}{\text{RPM}} (Where f = \text{Supply Frequency in Hz}, which ...
