1 hp single phase motor current rating

Full load current= (1.5*1000)/ (0,8*0.8*230) =10.2 Assuming a power factor of o.8 and efficiency of 0.8 and voltage of 230 V. Motors are always rated showing output and is to be divided by efficiency to get electric input. Hence next available ratings are 13 A and 16 A.13 A is not very common and so 16 A can be used.

1 hp = 745.7 watts Power = V*I I = Power / V I = 745.7 / 415 I = 1.79 A Therefore, current consumed is 1.79 amperes. Similarly, if voltage is 220 V, current consumed is 3.39 amperes.

For example a 1.5 HP Baldor motor turning 3450 rpm draws 13.4 amps on 120 volt service. A Leeson brand motor of the same specification list 12.4 

Example over 200 horsepower: Horsepower = 275, Voltage = 460 Chart value of 1.2A/ HP multiplied by 275 HP = 330A. 330A X 1.25 = 412.5A. Closest standard current transformer ratio is 400/5. For single phase motors , determine full load current from the nameplate rating. Multiply by 1.25 to get the approximate CT rating, as shown above.

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. First, compute the electric power input:

5/1 · Here are the typical Full Load Amps (FLA) for 220VAC and 120VAC 1 phase 60hz electric motors For 230VAC 1 phase 60hz electric motors, divide the following values by 2. Cart 0

The below chart breaks down the values based on single phase or three phase power which would be the power supply in your area as well as standard voltages. You will need to know these two values to accurately determine the amp draw based on horsepower. An electric chain hoist uses a motor for the lifting operation.

What would be the Hp rating of the motor which has rated input AC voltage of 230V and rated current of 3.8 Amps with 0.86 pf. HP = 0.00134 x 230 x 3.8 x 0.86= 1 Hp. The Single phase motor capacity is 1 HP. By revising this calculation, 1 HP single phase motor takes 3.8 Amps. AC 3 phase Amps to HP conversion Formula
