Formula for rpm of motor
WebDec 27, 2024 · So for example if the motor spins at 10,000 rpm on 24 V then with 40% PWM applied it should run at 10,000*0.4 = 4,000 rpm. With 20% PWM it should run at 10,000*0.2 = 2,000 rpm. This is equivalent to running the motor on 9.6 V or 4.8 V. This has not been my experience. WebNslip = Ns – N (Speed in RPM) ωslip = ωs – ω (Angular speed in Rad/sec) Where. Nslip = Slip speed. Ns = Synchronous speed = 120f/P. N = Rotor speed of motor. The slip of induction motor is a relative term expressed in percentage. It is given by: Where.
