How do you calculate the power consumption of 3 phase 2.2 kW induction motor drawing 3A current at 400 volts and 0.9 PF?
The power consumed can be calculated directly from the current draw, voltage, and power factor: (3A) x (400v line to line) x (sqrt(3)) x (.9pf) = 1.87kW. This would be a reasonable value for a 3hp motor that is not running under full load (the motor may be slightly over-sized for this application). The size of the motor is irrelevant to this calculation, although it shows that it is running at ~85% of its capability.Another AnswerSince a motor is a balanced load, we use the following equation to find its input power:power = 1.732 x line voltage x line current x power factor.So, in your example,power = 1.732 x 400 x 3 x 0.9 = 1870 WObviously, it cannot be delivering 2200 W when its input is just 1870 W. However, to determine its output power you will need to determine its efficiency at that input.
