how to calculate full load current of 3 phase motor
3 phase: Full load current=(746*hp)/(1.732*V*pf*eff) or KW/(1.732*v*pf*eff) hp=horse power v =Voltage pf=Power factor ef=efficiency 1 hp=745.7 W=0.746 kw Single phase motor Full load current table [Horse power,Kilo watt] Three phase motot Full load current table [Horse power,Kilo watt] to calculate the motor full load current one should know motor power factor, supply voltage and phase of supply. Assuming your motor is with 0.85 pf and 3 phase, 415V source then P = (Sqrt3)*V*I*pf 18500 = 1.732*415*0.85*I hence I = 30.2A. ... the efficiency to calculate the motor full load current? ... V, 3 Phase, 0.8 p.f, 89% efficiency at full load. To calculate the full load current (FLC) with the rated power, voltage and phases use the following formula if it is DC; A= KW X 1000/E; If it is AC 1 phase A= KW X 1000/E X PF; if it is AC 2 Phases KW X 1000/2 x E X PF; if it is AC 3 Phases A= KW X 1000/ 1.73 X E X PF where: A = amps; KW= Power; E = Voltage; PF= Power Factor How calculate ampere for electric motor? ... 37 kw,415 VAC,3 phase and 80% pf,calculate the full load ... motor .find out full load current? Now, if you look at the 1,000 4 1.732V portion of this equation, you can see that by inserting the respective 3-phase voltage for V and multiplying it by 1.732, you can then divide that quantity into the 1,000 to get a specific number (or constant) you can use to multiply kW to get the current draw of that 3-phase load at the respective 3-phase voltage. Table 2 lists each 3-phase constant for the respective 3-phase What is the formula for calculating "full load current"? ... Three-Phase Alternating-Current Motors. Full Load Current is ... calculate full load current? There are several different AC motor types, each one with different operating and mechanical characteristics. 238 2014Eaton Short-Circuit Current Calculations Three-Phase Short Circuits M 2 1 3 System A Available Utility Infinite Assumption 1500 KVA Transformer How to Calculate/Find the Rating of Transformer in kVA. Single Phase & 3 Phase Transformer always rated in kVA. formulas to find the rating of Transformer The full-load current (I FL) equivalent to the horsepower rating of motor is obtained from Table 430.247, Table 430.248, Table 430.249, or Table 430.250. 2004 Microchip Technology Inc. DS00889B-page 3 AN889 MOTOR DRIVE The 3-phase induction motor is connected to a 3-phase inverter bridge as shown in Figure 3 The Rotary Converter is designed to supply full running current to a three-phase motor normally providing it with full running torque.
