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.

A three-phase motor may be run from a single-phase power source. However, it will not self-start. It may be hand started in either direction, coming up to speed in a few seconds. It will only develop 2/3 of the 3-φ power rating because one winding is not used. 3-φ motor runs from 1-φ power but does not start . Single Coil of a Single Phase Motor

1 hp 3 phase motor amps rating is 1.83 amps on full load; however, 1hp single phase motors draw 16 amps on full load. That is why 1 hp 3 phase motors are more efficient than single phase motors. The efficiency rate of 1 hp three phase motors is 73% to 75% making them suitable for low-speed industrial purposes.

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

First, the type of the AC contactor for the motor generally adopts the ac-3 series. Then, the working current of the motor is estimated: I=5.5*2=11A. At last, the working current of the AC contactor can be about: 11*1.5=16.5A. We can choose 18a, which is slightly larger, as the working current. This means that we adopt the CJX2-1810 AC contactor.

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.

The single coil of a single-phase induction motor does not produce a rotating magnetic field, but a pulsating field reaching maximum intensity at 0° and 180° electrical. Single-phase stator produces a nonrotating, pulsating magnetic field. Another view is that the single-coil excited by a single-phase current produces two counter-rotating
