Actually 60amps wouldn't really be enough for full capabilities of a 750watt inverter. They can peak way over 1000watts.
I think it is worth the investment in solar panels for your home. In the long run you will have the return. Not to mention any surplus that can be sent back through the...
Building a motor like that might be fun for some but to me, I see nothing but mechanical issues that can not be over come.
However, if one actually over came the mechanical issues and build such a motor successfully, would it really be obtaining energy from nothing? Not really. Hypothetically...
750watts is useful but to try to run high powered appliances would not be recommended. I would recommend a 2000watt inverter run off of a 100Ah battery And if solar is the main charging station, a 30amp @12v would be the fastest charging I would recommend. but no less than 10amps.
So you...
I think its fine. It simply won't operate on 7v. Hence why it seems not to work. Input the proper voltage. 5V I would suggest, and I think you will find that it is not damaged.
Earth Magnets used in DC motors do make motors more efficient. Technically they do contribute to the rotational force known as torque and RPM measurements. With out the Earth Magnets the motor would not operate unless replaced with coil field magnets. Not only is there a loss in the resistance...
Yes you can. HV is two legs of 110. (220) But if you do that the amps will be cut in half.Instead of 6 amps it will be only 3 amps. What use would you have with a HV 3amp power supply?
Hmmm... maybe run a European electric razor.
