It depends on the inverter. Keep in mind that the average starting current of a motor is four times its running current, so the inverter would need to be able to handle a 54 Amp transient. (Or higher, depending on design margins.)
hi.. this is pankaj working as power engineer. we have a 11 kw induction motor which is used in fluidising blower. its no load current i sarround 9.5 to 10.6 amp. and under load its ampere does nt exceed 15 amp. its winding resistance is 1.4 ohm.
The running time depends on two things: the actual power the inverter can supply, and the actual power drain of the loads. A 1000 VA inverter may be able to supply 1000 VA, but it battery size determines *how long* it can supply power for. A 100 amp battery can probably supply 10 amps for 10 hours (100 amp-hours), but it may only supply 100 amps for perhaps 45 minutes - if it does not overheat! Generally, batteries give less effective power at higher power drain. You also need to know how efficient your inverter is - it may be 90%-plus, it may be as bad as 75% or less. So you will need to (1) find out how much power your appliances draw (let's say its 300 watts), then (2) examine the specifications for the inverter-battery combination to discover how long they can support your power drain. Be aware that 300 watts load is over 25 amps current drain at 12 volts, so you are already getting away from the 100 amp rating, to a lower value due to the high power drain on the battery.
Yes but only up to a load torque of 8/9 of the rated torque.
power , P=1.732*V*I*power factor so, the formula for calculate the load current for a 3 phase motor is,I=P/(1.732*V*power factor)
Need to know the horsepower of the motor.
Yes, a 400-watt power inverter can operate a 5.3-amp power tool, as long as the tool's voltage matches the inverter's output. To determine if it's feasible, multiply the amperage by the voltage (typically 120V in the U.S.), which gives a power requirement of about 636 watts (5.3A x 120V). Since 636 watts exceeds the inverter's capacity, it may not operate the tool efficiently or could overload the inverter.
Need to know the running amp draw. Starting amps would be useful l too. The average amp draw for a simple 1hp motor is about 7 amps, such as a fan motor. Ohms law says amps times voltage = watts, so 7 amp times 120v=840 watts. Consider that starting amperage is about 1-1/2 times running load, starting watts would be about 1200. You would need about a 1200 watt inverter to run that motor.
160 amps is more than ample to run a 100 amp inverter.. what you need to look at is the required input amperage of the inverter and compare that to what's present in the circuit it's wired/plugged into. In most cases, you should be able to run up to a 400 amp inverter plugged into a 12v outlet, but again, you need to make sure.
To calculate the size of the inverter needed, multiply the device's operating voltage (115V) by its current draw (3.0A) to get the power consumption in watts (115V * 3.0A = 345W). To be safe and accommodate any power surges, choose an inverter with a continuous power output of at least 400-500 watts.
One would assume the chainsaw requires 120 volts or more if you want to run it with an inverter. If your chainsaw uses 16 amps at 120 volts then your wattage is Volts (120) x Amps (16) and that would be 1920 watts. So you will require a much larger inverter to run your chainsaw.
To determine the size of the inverter needed for a 7.5 amp grinder, you first calculate the wattage by multiplying the amperage by the voltage. Assuming a standard voltage of 120 volts, the grinder would require 900 watts (7.5 amps x 120 volts). It's advisable to select an inverter with a higher capacity to handle the startup surge of the grinder, so a 1200 to 1500-watt inverter would be suitable.
The formula for watts (or power) is Amps times voltage. Therefore with a 6 amp draw times 120 volts would be about 720 watts. A 1000 watt power inverter would do the job.
The 40 amp motor probably produces double the horsepower of the 22 amp motor.
depends on your load...
The Boss SmartVac 4870GZ uses a 12-amp motor.
To determine the number of amps a 500-watt power inverter draws, you can use the formula: Amps = Watts / Volts. Assuming a common household voltage of 120 volts, a 500-watt inverter would draw approximately 4.17 amps (500 watts / 120 volts = 4.17 amps). If the voltage is different, the amp draw will vary accordingly.
Uh, no.
