A 50-hp three-phase motor, rated 220V, 75% power factor, has 6 poles. The slip at full load is 3%. What is the frequency of the rotor current at full load?
Added by Sheri M.
Step 1
First, we need to calculate the full load current of the motor. We can use the formula: I = P / (sqrt(3) * V * PF) where I is the current in amps, P is the power in watts (converted from horsepower), V is the voltage, and PF is the power factor. Converting 50 Show more…

A 12 pole, 50 Hz, 3 phase induction motor runs at 485 rpm. What will be the frequency of rotor current?
A 4-pole, 3-phase induction motor operates from a supply whose frequency is 50 Hz. Calculate: The speed at which the magnetic field of the stator is rotating. The speed of the rotor when the slip is 0.04. The frequency of the rotor currents when the slip is 0.03. The frequency of the rotor currents at standstill.
