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.)
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.
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.
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.
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.
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.
Uh, no.
7.75 amps
You will need a battery charger capable of providing up to75 amps at 12 volts DC. This is called a converter, not an inverter. An inverter takes 12 v and transforms it usually to 120v AC or 220v Ac. Keep in mind that your 1000 watt amp will not draw 100 amps only briefly at times if at all unless you are at maximum volume. You probably could get by with a 50 amp charger and a big capacitor to supply the boost for a few seconds.
It's the power the tool draws if you run the motor at full speed then stall it out.
You're asking about something that is potentially very dangerous. There is some very specific equipment that isolates an inverter from the utility main. In the event of a power failure, if your equipment is installed improperly you could cause injury to utility workers. Do NOT install the inverter if you are not properly trained and have an adequate knowledge of not just electricity, but also extensive knowledge of the inverter and disconnect equipment.
At peak power it should draw 1.36 amp at power factor 1 or more realistically 1.7 amp at power factor 1.7.
