A 3-phase, 50 Hz, 12 pole induction motor has star connected rotor and...
Ohms. The motor is rated for 10 kW at full load and has an efficiency of 92%. The stator winding has a voltage rating of 415 V.
To calculate the current drawn by the motor at full load, we can use the formula:
P = √3 × V × I × cos(θ)
Where P is the power in watts, V is the voltage, I is the current in amps, and cos(θ) is the power factor.
Rearranging this formula, we get:
I = P / (√3 × V × cos(θ))
Substituting the values given, we get:
I = 10000 / (√3 × 415 × 0.92) = 17.3 A
To calculate the rotor resistance per phase, we can use the formula:
Rr = (slip × V^2) / (2 × π × F × (Tstall / P))
Where slip is the slip at full load, V is the rated voltage, F is the frequency, Tstall is the rated torque, and P is the number of poles.
Substituting the values given, we get:
slip = 0.04 / (2 × π × F) = 0.000127
Tstall = (10000 / (2 × π × F)) / (0.92 × 0.85) = 53.5 Nm
Rr = (0.000127 × 415^2) / (2 × π × 50 × (53.5 / 12)) = 0.158 ohms
Therefore, the rotor resistance per phase is 0.158 ohms.
To calculate the current drawn by the motor at full load, we can use the formula:
P = √3 × V × I × cos(θ)
Where P is the power in watts, V is the voltage, I is the current in amps, and cos(θ) is the power factor.
Rearranging this formula, we get:
I = P / (√3 × V × cos(θ))
Substituting the values given, we get:
I = 10000 / (√3 × 415 × 0.92) = 17.3 A
To calculate the rotor resistance per phase, we can use the formula:
Rr = (slip × V^2) / (2 × π × F × (Tstall / P))
Where slip is the slip at full load, V is the rated voltage, F is the frequency, Tstall is the rated torque, and P is the number of poles.
Substituting the values given, we get:
slip = 0.04 / (2 × π × F) = 0.000127
Tstall = (10000 / (2 × π × F)) / (0.92 × 0.85) = 53.5 Nm
Rr = (0.000127 × 415^2) / (2 × π × 50 × (53.5 / 12)) = 0.158 ohms
Therefore, the rotor resistance per phase is 0.158 ohms.
