Power in KW = 1.5 *746/1000 = 1.119. Note 1 HP = 746W. Therefore, I =. (1.119 * 1000)/ (240 * 0.8*0.85) = 6.86 Amps. Suppose we have a 3-phase, 10KW, AC Motor with 415V, line voltage 3-phase power source and power factor 0.8 and efficiency of 88%, the full load current will be arrived at by manipulating the power formula for 3-phase motors to

2022/2/19 · Estimate the power in watts (the nominator of the expression), 1 hp * 746 = 746 W; Evaluate the product in the denominator, 200 V * 0.92 * 90% = 165.6 V. You can always convert decimal to percent to make your life easier ( 90% = 0.9 ); Make a fraction of these numbers and find the final horsepower to amps value, 746 / 165.6 = 4.505 A.

Even though your 1 hp motor is rated 13amps at 120 vAC, that rating is at full load. If the motor is over loaded, it could draw much more. Also, starting current for a single phase motor can be very high, as much as 6 times the full load current. If you are using the plug to start the motor, the starting current may be heating the plug.

For example, consider a 1 hp single-phase motor with a power factor of 0.75 and an efficiency of 85% and is used to drive a pump. If the engineer determines the voltage and current values to be 124V and 12A, respectively, then the following calculations can be used to determine if the motor is overloaded.
