Electrical Motor Power, Velocity and Torque Equations. Torque in Imperial units can be calculated as. T inlb = P hp 63025 / n (1) where . T inlb = torque (in lb f) P hp = horsepower delivered by the electric motor (hp) n = revolution per minute (rpm) Alternatively. T ftlb = P hp 5252 / n (1b) where
It is easy to calculate angular speed if you know rotational speed of the motor in rpm: ω = rpm * 2π / 60. where ω – angular speed, measured in radians per second (rad/s); rpm – rotational speed in revolutions per minute; π – mathematical constant pi (3.14). 60 – number of seconds in a minute.
The speed of an induction motor can be calculated using the following formula: Synchronous Speed (Ns)=120×Frequency (f)/ Number of Poles (P) where: Synchronous Speed (Ns) is the speed of the rotating magnetic field in revolutions per minute (RPM). Frequency (f) is the frequency of the power supply in Hertz (Hz).
The speed at which an electric induction motor operates depends on. The speed of electrical motors with 2, 4, 6 or 8 poles at 50 Hz and 60 Hz.
23 maj 2017 · The synchronous speed of the rotor in RPM N = 120f/P where f is the frequency of the stator current and P is the number of poles. The operating speed No = N - Ns where Ns is the slip speed. The frequency of the rotor current fr = Ns x P/120, so fr = 0 if the slip is zero.
Enter the input voltage in volts, current in amps, speed in RPM and power factor. Choose the motor types. For DC motor, pf is one.
