Usually, I have gotten away with this, BUT... depending on the quality of the windings in the motor, it could burn through the tiny wire in the motor winding. I have done this many times with no problem, but have also burned out a few motors.
One good example is that I have several [from the "early" days] cordless drills. The early ones used anywhere from 6 to 9 volt battery packs.
I then bought a 12 volt drill at Harbor Freight and Tools, and when I got it home and examined it I realized that the 12 volt battery pack was IDENTICAL in size to the older 6 and 9 volt packs.
So, after charging the new 12 volt pack, I tried it in the older 6 and 9 volt drills. Lo and behold, it worked fine, with just a little more RPM and drilling power.
I then called my Electrical Engineer brother and asked him about it and he said that those small drill motors are not that sensitive to even a doubling of voltage and perform OK with 12 volts on 6 and 9 volt units.
That was about 4 or 5 years ago, and for some time, I've been using 12 volt battery packs for all three units [6, 9, and 12 volts]. When time came to replace failed 6 and 9 volt units, I switched to 12 volt packs for all 3 drills.
Again, I think 12 volts will be safe for your 9 volt motor, but it depends on the motor.
A 3 volt motor will burn with a 9 volt battery. Not recommended.
You could but the car would not run properly and would be very slow. I would highly advise against this as it might also damage the motor.
When using the Inverter the CCU can be adapted to the users needs. A regular 12 volt battery would work on any small devices.
You can use an insulation rating 5000 volt to run 4160 volt supply.
Yes it will burn the motor in less than a minute. Use a 12 V battery to run a 12 V motor. Not exactly true. I rebuilt many engines and often to get them turned over I would use two batteries hooked up for 24 volts. The ignition was wired for 12 volts. When an engine is personally rebuilt it can be very hard to turn over. Once it runs a bit, I revert back to 12 volts. As long as you don't run the motors too long (meaning 4-6 revolutions) or to the point where they get hot, they should be fine. Electronics is another matter. Starter motors are often built with heavy wiring and can take the heat.
Start capacitors and run capacitors are two different types of capacitors. They alter the current to create a rotating magnetic field. They have two or three terminals to which the wires are attached.
You can but the motor may not run, however you will not burn the motor.
Possibly but but not for long. The 12v motor will draw more current than the 9v battery can supply and the undervoltage will cause the motor to run hotter than normal thus shorting its usefull life.
No. The motor was designed to run on a specific voltage and any variance from it will not work. The amperage of the motor is what you should be looking at. A single 1.5 volt battery neither has the voltage nor the capacity to produce any thing close to the amperage you would need to run the 12 volt motor.
If you can get the battery to run the motor, write it up in a science journal. You'll be rich. Sure but what are you going to use to power the 12 volt motor? You will have to use another battery which you could just use to power the radio in the first place.
It depends on the battery's voltage. Such a battery's capacity is given in ampere-hours, not amperes. An 850 amp-hour 12 volt battery can theoretically operate a 12 volt motor for about 12 minutes but in practice it's probably, maybe a lot less, since the motor will probably stop as the battery nears its depletion.
it can get really hot and burn the circuit
I believe linear motors need AC power. This would rule out any battery.
You "could" run a 120V 5A window AC unit off a 12V deep cell battery but, assuming 100% efficiency (something you can never get), you would need an inverter or motor-generator set and 50A out of the battery to run, and maybe 5 or 10 times that to start.
Can I run 480 volt , 60 HZ motor at a 380 volt , 60 Hz system?
No, unless the motor was wound for dual voltage operation, which it will state on the motor nameplate, a 110 volt motor run on 240 volts will be damaged.
no
Yes - you can run a 1200 watt motor on a car battery - until the energy of the battery is exhausted.
