Q:I am converting an older car to hybrid. I would like it to have about 200 horsepower and around 250 f/lb of torque, with a fairly flat torque response. It will be powered by a fairly large battery pack, which will be charged on the fly by a jet turbine engine. The final car weight will probably be ~3000 pounds, not including the motor. I am in the first planing stages of this little project, so any suggestions at all are most appreciated.

I hope you have lots of money to spend. What you are making is an electric car with an on board gas powered generator. Hybrid vehicles use an electric motor to assist the gas engine and in-turn convert braking energy back into electrical energy which is stored in the battery.

Q:Is permanent magnet synchronous motor AC servo motor?

NoPermanent magnet synchronous motor rotor is a permanent magnet, stator coil, often used as generator or collection of speed signals.AC servo motor is a kind of motor that can be accurately located.

Q:Why are electric hair dryers divided into direct current motors and alternating current motors? What are their differences?

DC motor: fast speed, light weight, simple structure, easy to damage, big sound making

Q:What are the speed regulating methods of AC motors? Detailed point

(1) rotor circuit series resistance: used in AC winding asynchronous motors. The range of speed regulation is small, the resistance consumes power, and the motor efficiency is low. Used of cranes.(2) change the speed of power supply voltage, the speed range is small, the torque decreases greatly with the voltage drop, and the three-phase motor is usually not used. Used for single-phase motor speed regulation, such as fan.(3) cascade speed regulation, in essence, is the introduction of additional rotor electromotive force, change its size to speed. It is also only used in wound motors, but the efficiency is improved.(4) electromagnetic speed regulation. Used only for slip motors. By changing the exciting coil current, stepless smooth speed regulation, the mechanism is simple, but the control power is smaller. Not suitable for long term low speed operation.

Q:im trying to get two compressors to work of a single pressure switch?thanks a lot!

The starting current for the two motors would be near 100 amps surge. The motors would need to be on their own circuit breaker. As for the pressure switch controlling both motors, pressure switches are usually designed to operate a single motor. Going through a contactor would be your best solution with the pressure switch controlling the contactor coil.

Q:is it necessary to use both ac and dc motor in car??

dc that is what it is desighned for

Q:How Do I combine several AC fans, that I removed from old microwaves together to generate more electricity? can I simply wire the alike wires together? my other question is other than using a multimeter is there something I can purchase that will tell me how much voltage is currently being made, and lastly is it as simple as wiring an outlet into these fans to plug into?

I imagine your AC fans have inductive motors, that is, the windings in the stationary part of the motor induce a voltage in the rotating part to give it it a magnetic field to push against and cause the rotation. You cannot use these motors as generators as is, you can rotate them all day long and they will not produce voltage. If you did have motors that could be turned into generators, you would need a voltage controller to make sure the output voltage stayed at the voltage of what you plug into, otherwise, you will have motors! Even big power company generators have protection to prevent this called anti-motoring circuits.

Q:it has 3 wires coming out, what are they for?

If one of the wires is green or has a green stripe, it could be a ground wire. If there is not a box on the side of the motor with a capacitor inside, one of the wires could be for connecting a capacitor. I would think that a garage door opener motor would be reversible. That should require 4 wires. If you knew the model number of the opener, its approximate age, the colors and relative sizes of the wires, and/or something about what was in the Craftsman control box you might have a better chance of figuring this out. It would also help to have a multimeter and know how to use it.

Q:What are the direct and alternating current motors used in daily life?

Friends, DC motors have toy motors, toy cars, toy planes, razors, rechargeable power tools, and in short, all batteries or batteries are DC motors. AC motor home pulverizer, threshing machine, ragweed machine, milling machine, water pump, submersible pump, booster pump, blower, electric fan, compressor, grinding machine and so on the use of electricity directly to work is AC motor.

Q:Im trying to make tattoo gun what would be a better motor 18volt ac or 18 volt dc?

DC because it's safer. If you don't know what you are doing you could kill someone with ac, even at 18 volts.
