I need an electric motor for a battery operated cutting tool that I'm developing. All major search engines seem to provide an overwhelming amount of product that doesn't match what I'm looking for. If anyone knows a great place to find electric motors, gears, and shaft connectors, it would be greatly appreciated. The approximate specs of the motor I need are: 12V DC, an offset shaft gearhead with an output speed greater than 5,000rpm, and a diameter less than 2".

If you are in the R&D stage, the best place is American Science & Surplus. There may be a store in your area, if not, they do have a website, however it is much more fun to go to one of the stores & have the hands-on with all of the gadgets.

utilising a resistor or reducing the voltage additionally will cut back the skill (torque) the motor can generate. THe motor will stress under the burden in spite of if it incredibly is desperate too gradual with those methods and could burn out. additionally the resistors used would be producing warmth so if the esistors are no longer sized with adequate wattage score they're going to dissipate. in case you desire authentic speed administration you elect a Pulse Width Modulated (PWM) controller. this form of administration applies finished skill to the motor in short pulses. The greater pulses and the longer the coronary heart beat the speedier the motor will bypass. The benefit to this technique is that finished torque of the motor is often attainable no count number what speed and that extra skill in no longer wastes in this form of heat like whilst utilising a resistor. in the adventure that your reachable with a solder iron you may get a kit for around $25 to $15. additionally evaluate utilising the comparable set up yet utilising mechanical speed help with the two gears or pulleys. in case you employ 2 stepped pulleys you are able to easily replace belt positions to get carry of different speeds. Mechanical speed adjustment will easily supply a fastened sequence of speeds.

You need to determine the "horsepower" or "wattage" (kVA) for your need.
I would suggest "Grainger" www.grainger.com. They will recommend a motor best suited.

It sounds like a battery powered dremel tool see:
