Motor Kw Rating Chart. Protection enclosure totally enclosed ( ip 55 ). So the friend keeps watch and enjoy it.
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. Output range 0.37 kw ~ 315 kw ( 50hz ) or 0.43 kw ~ 362 kw ( 60hz ). Both are parameters for the motor.
Motor Kw = 90 Kw Pf = 0.8, Efficiency = 94% System Voltage, V1 = 415 Cable Length = 100 M P = √3 X V X I Cos Φ For 3 Phase Load P = V X I Cos Φ For 1 Phase Load Rated Load Current = P / (1.732 X V X Pf X Eff) I= 90000 / (1.732 X 415 X 0.8 X.99 ) =90000/540= 157 Amp ~ 157 A
2 it’s a very easy way here to know the motor ohm values chart & set up the coil size of the motor. (syn.) 3000 ~ 750 r.p.m. These ratings are the same as the manufacturer standard ratings, 11, 15, 22, 30, 37 kw, etc.
For Example, A 750 Kva (600 Kwe At 0.8 Power Factor) At 480V Produces 902 Amps, Or Double The What Is Shown In The Table For 375 Kva.
Equivalence 3,28 amperes 2 kw: 1 motor ohm values chart.; The information in this chart was derived from table 50.1 of ul standard 508a.
Peak Efficiency Is At 7.5 Hp.
31 rows motor rating hp approx. Maximum efficiency is usually near 75% of rated load. 33 rows three phase motor loading chart.
Generators Must Be Sized To Deliver At Least 65% Of The Rated Voltage During Motor Starting To Ensure Adequate Motor Starting Torque.
Maximum starting current 6 x rated motor current. Most electric motors are designed to run at 50% to 100% of rated load. Please note that this table is intended to be used as an estimate of how many amps a generator outputs during operation and is not an exact representation due to various factors that can increase or decrease this value.
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.
A motor with a service factor can occasional be overloaded. 8.5t means ~5000 rpm 10.5t means ~4,200 rpm 13.5t means ~3,300 rpm 17.5t means ~2,200 rpm 21.5t means ~1,800 rpm so kv and turns are essentially the same: Single phase motors motor rating approx.
