WebApr 12, 2012 · FLA is the nameplate amperage rating of the motor when it is running at its designed horsepower and on the motors designed voltage. 746 watts = 1 HP. The FLA of a 1 HP motor at 240 volts would be ... WebSuppose we have a 3-phase induction motor with a power rating of 15 kW and is connected to a power supply of 415 V. The power factor of the motor is 0.85. We can calculate the amp rating of the motor as follows: Amp Rating = (15,000 × 1000) / (√3 × 415 × 0.85) = 24.98 A. Therefore, the amp rating of the motor is 24.98 A.

WebAn induction motor's speed is always less than synchronous speed and it drops off as load increases. For example, for 1800 rpm synchronous speed, an induction motor might have a full-load speed of 1748 rpm. On standard induction motors, the full-load speed is typically 96% to 99% of the no-load speed. This is known as slip.
