Step 1: Multiply the amps by the voltage indicated in the formula and divide them by 1000. For example, a three-phase fan (3P) has a current of 10 A with a voltage of 208 VL-L, multiply 10 A by the voltage of 208 V , the root of three and divide by 1000, which will result in: 3,6kVA. (10Ax208Vx√3) / 1000 = 3,6kVA).
3. Both your machines use transformers inside to create the required working voltage. Using transformers at 60Hz designed for 50Hz will be no problem. Using one at 50Hz when designed for 60Hz is more troublesome, as the max flux inside the core will be greater than designed. So for you 60Hz 220-230V is fine.
The 220v power supply can use this if you don’t want to increase the voltage. The current will be too high because the current is too low because the original three phase 380V power supply voltage winding is now used for 220V power supply. Changing the direction of rotation of the 3-phase 380-V Power Supply.
Rta: // The first thing to do is multiply the Hp by 746, then you must divide the previous result between the multiplication of the voltage line line, the efficiency, the root of three and the power factor, giving as a result: 12.33 Amps . (80Hpx746) / (4160Vacx0.84 × 0.8x√3) Example 2:
Assuming constant element resistance and neglecting the rather epensive option of using a transformer to boost voltage to 400 and rewiring all elements in parallel, you will get only (240/400)^2 or 36% of the rated input power on 240 volts. This translates to 1/0.36 = warmup times about 2.8 times longer than normal for the power rating.
Below is the AC single phase amps to watts calculation formula used by our AC wattage calculator: P = PF × I × U. where: P – Power or wattage; PF – Power factor; I – Electrical current; and. U – Voltage. This formula means that the wattage equals the power factor multiplied by the current multiplied by the voltage.
The speed of 50 Hertz 2 poles synchronous generator is 3000rpm. AC power frequency is determined by the pole number of the generator p and speed n, Hz = p * n /120. The grid standard frequency is 50Hz, which is a constant value. For a 2-pole motor, the speed n = 50 * 120 / 2 = 3000rpm; for a 4-pole motor, the speed n = 50 * 120 / 4 = 1500rpm.
Three single phase lines, separated in phase by 120°, make a 400V 3PH supply. Notice that 230V * √3 = 400V. In the USA there is a little more legacy confusion. The single phase voltage was 120V which made three phase 120V * √3 = 208V. Industrial equipment in the USA can be hard-wired using either 120/208V or 277/480V.

600V to 36V DC/DC converter, 400W. The DY400-DD36-600 is a 36V converter of 400W. The converter can convert 600V to 36V DC and supply a DC current of 11,1A to 13,8A. In. 600VDC. Input range. 510 - 690VDC.
The speed of an Electric Motor is determined by Voltage and Frequency. So, a 400V 50Hz Motor will run at rated speed at 400V x 50Hz and half rated speed at 200V x 25Hz. Provided this Voltage x Frequency ratio is maintained, the Motor will operate at full Torque – ideal in a Lathe application where speed must remain constant even when a load
