In understanding motors, it’s important to know about slip. Slip shows the difference between the motor’s magnetic field speed and the rotor’s speed. It is calculated as N = (1-s)Ns. This highlights why knowing the RPM formula matters.

Parameter | Description | Formula |
---|---|---|

Synchronous Speed (Ns) | Theoretical speed of motor’s magnetic field | Ns = 120*F/P |

Slip (s) | Difference in speed relative to Ns in % | s = (Ns – N)/Ns * 100% |

Rotor Speed (N) | Actual speed of motor’s rotor | N = (1-s)Ns |

Gross Torque (Tg) | Used to calculate rotor’s gross output power | Pm = Tgω |

Shaft Torque (Tsh) | Used to calculate output power | Pout = Tshω |

Induction Motor Efficiency | Includes rotor efficiency and overall factors | Efficiency % = (Output/Input) * 100 |
