How many amps for 20 hp motor 3 phase
Web= 472V x 20A x 0.90 x 0.85 x 1.73/746 = 17 Hp The quickest method to closely estimate motor horsepower is to use a digital clamp meter to measure current and voltage to the motor, and then perform a simple calculation. Use this formula to estimate motor horsepower. Horsepower (hp)= Voltage x Amperage x % EFF x power factor x 1.73/746. WebHP to Three phase amps calculation: AC three-phase current I (A) in amps is equal to 746 times of the total power P ... A 10 HP AC three-phase motor has 415 Volts of voltage with 0.86 power factor, calculate the line current. AC three phase line Current =746*10 / (1.732*415*0.85) = 12.2 Amps.

WebWhether its a 3-phase or single phase voltage supply. Rating (P). The power rating of the motor in kW or hp. Power factor (cosΦ). The rated power factor of the motor. Typically around 0.86. Efficiency (η). The efficiency of the motor. Typically around 95%. Enter 95. How do you calculate motor current for a 3 phase and single phase motor? 3 ... WebFrom our cable size calculator, the full load current of the 5.5kW motor is 10A. Cable size = 1.5 x 10 =15 A. Hence, the required cable shall able to carry minimum 15A current. Look at the Cable current rating Chart, 2.5Sqmm copper has the ability to carry 18 Amps, hence 2.5sqmm is suitable for 5.5kW/7.5HP motor.
WebConverting AMPs to HP. If you know your motor’s AMPs, use this formula to get HP: Amps x Volts = Watts. With 1 HP being equivalent to 746 Watts, use this formula for final conversion: Watts / 726 = HP. Converting kW to HP. If you know your kW, but need HP: kW / 0.746 = HP. Converting kVA to HP. This is the formula for kVA to HP conversion: WebJan 17, 2011 · For a single phase 3 HP motor at 208 volts the amperage is 18.7 amps. For a three phase 3 HP motor at 208 volts the amperage is 10.5 amps. This figure is derived at by taking...
WebAccording to the NEC, the overload rating must not exceed 115% of the full-load current of the motor. For example, the full-load current of a 10 HP motor at 230V is 28 Amps. Therefore, the heater must be sized for 28 * 1.15 = 32.2 Amps. Conduit size in this table is conservatively based on rigid metal conduit with some spare capacity. WebHorsepower (hp) = Voltage x Amperage x % EFF x power factor x 1.73/746. = 472V x 20A x 0.90 x 0.85 x 1.73/746 = 17 Hp. The quickest method to closely estimate motor …
