Question

On the nameplate of a star-ring induction motor: 75 kW, 16 A, 380V, 1430 rpm. It is written cos φ-0.82 and f-50 Hz. If the ratio between Tipping (Maximum torque) and Rated torque of the motor is 2.2, find the overturn slip (Slip where the maximum torque occurs).

          On the nameplate of a star-ring induction motor: 75 kW, 16 A, 380V, 1430 rpm.
It is written cos φ-0.82 and f-50 Hz. If the ratio between Tipping (Maximum
torque) and Rated torque of the motor is 2.2, find the overturn slip (Slip where the
maximum torque occurs).

Step 1

The rated torque can be calculated using the formula: Rated torque = (Power / (2 * pi * Speed)) * 1000 where Power is given as 75 kW and Speed is given as 1430 rpm. Substituting the given values into the formula: Rated torque = (75,000 / (2 * 3.14 * 1430)) * 1000 Show more…
