Torque - Horsepower (hp) conversion is a method of converting one unit from other and vice versa. Torque is a rotational force generated by the electrical system, whereas, the horsepower is an imperial unit of power equal to 745.7 watts motor data calculators published by major electrical manufacturers. #10 1.26 #8 0.786 #6 0.808 Select motor size from horsepower column making certain you are in the correct voltage. 2.

This page shows the online AC Power calculator to calculate the AC current in a circuit for the given Power Factor Angle, Voltage, Current, etc. In Direct Current, the electric charge flows in only one direction. Whereas in Alternating Current, Electric charge in alternating current changes direction periodically Please solve my problem ,I want to run a three phase squirrel cage induction motor of 10 HP,415 volts rating by DOL Starter,Star Delta Starter and VFD(30Hz). Please tell me the overload relay range and its setting,contactor rating,TPN MCB rating for backup fuse protection and cable size in each case.Sir,please give me the full calculation for.

Figure 3 Relationships Between Power, Current, Power Factor and Motor Load Example: Input Power Calculation An existing motor is identified as a 40-hp, 1800 rpm unit with an open drip-proof enclosure. The motor is 12-years old and has not been rewound. The electrician makes the following measurements: Measured Values: V ab = 467V I a = 36 amps. Here is my mechanical 60 Hz to 50 Hz sine wave frequency changer. A 50 cycle MG set ( Motor Generator ), The alternator has been modified ( no diodes ) to output 120 VAC at 50 Hz by virtue of the belt pulley diameters. The drive is a 115 VAC induction motor drawing 9.6 Amps 60 Hz at 1725 RPM, that's over a Kilowatt about 1┬Į HP of input Power It is a conversion calculator which transforms the electric current in Amps to electrical energy in Watts. It has three text fields which help in determining the exact units you require after the conversion. The first text field requires you to select the current type. It can either be direct current, denoted as (DC) or alternating current (AC) Motor Output 0.37 0.55 0.75 1.10 1.50 2.20 3.70 5.50 7.50 9.30 11 15 18.50 22 26 30 37 45 55 75 90 110 132 143 0.5 0.75 1 1.50 2 3 5 7.50 10 12.50 15 20 25 30 35 40 50 60 75 100 125 150 180 19 Amps are a measure of electrical current in a circuit. In order to convert from kVA to amps we'll also need the voltage of the circuit, and then we can use the formula for power. The formula to convert kVA to amps is: Current (A) = Power (kVA) Voltage (V) This means that amps are equal to the kVA times 1,000, divided by the voltage

Calculate the CFM (volumetric flow of air) at 1,200 rpm. The volume of the column of air described in Step 2 is pi (3.1416) x fan radius squared (0.5-feet squared) times the column length in feet. This would be 3.1416 x 0.25 square feet x 800 feet = 628.32 cubic feet per minute at 1200 rpm Use this calculator to estimate cable voltage drop for sizing conductors. The calculation assumes uncoated copper or aluminum conductors operating at the temperature selected and is based on the ac/dc resistance or impedance from NEC 2011 Chapter 9, Tables 8 and 9 for stranded conductors operating on a DC or AC 60Hz system To demonstrate how watts can be converted to amps, we solved a few examples of how many amps is 500 watts, 1000 watts, and 3000 watts. In the end, you will also find a watts-to-amps table at 120V electric potential. Here's a quick useful piece of info: How many watts make an amp? At 120V, 120 watts make 1 amp. That means that 1 amp = 120 watts  • How many eggs will a parakeet lay.
