It depends on the refrigerator. Mostly the average is about 240~280v

So i wouldn't touch it if I were you!

How many watts does a 3 phase 20 hp motor use?

You would need to know the efficiency of the motor to determine its input power, which would, of course, exceed its output power of (20 x 746 =) 14.92 kW.


Is your power into motor equal to your power out of motor at no load?

For a motor's output power to equal its input power, the motor's efficiency must be 100%. As no machine, particularly a rotating machine, can possibly achieve 100% efficiency, there is no condition under which its output power can ever match its input power.


How do you convert hp to amp?

HP/.00134= Watts Then Watts divided by Volts = AMPS For expample. a .75 HP electric motor running on 220VAC uses 2.544 amps .75 / .00134 = 559.7015 Watts then 559.7015 / 220 = 2.544


Slip power in a induction motor?

slip power is a power which is develop by the induced voltage and current in an induction motor


What is the kva for 7.5 hp 3 phase motor for 1 hour?

1 hp is generally around 750 watts, so you can expect a 7.5hp motor at full load to be ~5.6kW.If lightly loaded, the motor will draw less current, thus less wattage. Also, you cannot calculate current directly from the kW rating and voltage (so full load current will not be 5600/230 = 24.3Amps), as motors are not 100% efficient, and do not have 1.0 power factor. I'd expect the full load amperes to be greater than the kw/voltage value by 20-30%.I looked up a Baldor motor stated to be 7.5hp, and it was ~7kVA, 5.6kW at full load.Another AnswerYou don't specify whether you want to know the machine's output power or its input power.The rated power of a motor is always its output power. In North America, this is expressed in horsepower whereas, in the rest of the world, this is expressed in watts (in practice, kilowatts). As 746 W is equivalent to 1 horsepower, then a 7.5 horsepower motor is equivalent to 5.6 kW.If you wish to determine the rated input power to a machine, which is always larger than its output power, then you must know its efficiency at its rated output power. Divide the output power by the efficienty (expressed as a per unit value).

What motor has more power one at 120 volts or one at 208 volts?

The voltage of the motor does not determine the power. However it does determine how many Fla... Or full load amp it will have when the motor is at highest speed. Usually the lower the voltage the higher the amps On the same motor. Most motors will have a name plant with this information and you should always get the amount of horsepower motor you need and make sure it will be compatible with your power source.


How many kw can a 12 volt motor generate?

It depends on the current rating of the armature winding, which will determine its input power. It's output power then depends on the motor's efficiency.


What is full load current of 2HP induction motor?

Since (in North America, at least), the horsepower of a motor describes its rated output power, you need to know its efficiency in order to determine its input power, then its rated voltage, to determine its full-load current.


How do you determine the power supplied to a motor with 1.0mA of current at 3.0V potential difference?

current times voltage equals watts or power


2004 Chevy truck truck blower motor repair?

You gotta start by figuring out what's wrong with it. You need to determine if it's the blower motor itself, or the power supply, then troubleshoot to determine the exact cause.


What is the maximum motor power of the Chevrolet Astro?

The maximum motor power of the Chevrolet Astro differs due to the fact that there are several different types of this car. Looking at the 1995 version, however, one can determine that the maximum motor power of the Chevrolet Astro is 195 hp at 4,000 rpm.


The blower on your 1999 DeVille heater stopped working how can you determine if it is the blower or the control circuitry?

Check to see if you are getting power to the blower motor - if so motor is defective if not problem in circuitry to blower motor


How many amps does a 5.5 kw 380 v three phase motor draw?

Current drawn = 5.5 / (1.732 X Voltage X power factor)AnswerWithout knowing its efficiency, you cannot determine the input power to this motor (5.5 kW is its output power), so you cannot determine its current.

How many electricity consume 5HP motor in 1 hour?

I assume you are asking how much energy a 5-hp motor will consume in one hour?The first thing to understand that a motor is rated according its output power which, in North America, is expressed in horsepower and, elsewhere, in watts. So, the output power of your motor is 5 hp, which is equivalent to 5 x 746 = 3730 W.Next, you need to find out its full-load efficiency. You then need to divide the output power by the efficiency to determine its input power -remember, input power is always higher than the output power.Once you have found out its input power, convert that into kilowatts and multiply it by one (hour) to determine the energy used in kilowatt hours.
