The power output of a motor can be changed by the use of gears.

Gears can be used to increase torque by reducing the speed of the output shaft

by placing a large gear on the output shaft, coupled to a smaller gear.

Conversely, by using a small gear on the output shaft, coupled to a larger gear, the speed can be increased with a reduction in torque.

How do you power a 3 volt DC motor with a 12 volt battery?

you would have to put some type of resistor in the circuit with the motor...the resistor would have to be in series with the motor and would have to be of a high enough value to lower the voltage by 9 volts....There is a formula for working this out but you would need the amperage of the motor to figure this....

Does miliamperes increase as does battery voltage when put in a series configuration?

The current in a circuit, expressed in milliamperes, is1,000 x (battery or power supply voltage)/(resistance connected between the power supply terminals)If you increase the voltage of the battery or power supply, the current in the circuitincreases proportionally, at least until something in the circuit gets hot, melts, fuses,and opens the circuit.


Effect of under voltage on induction motor?

Undervoltage is defined as a condition where the applied voltage drops to 90% of rated voltage, or less, for at least 1 minute. Low-voltage conditions occur when a facility asks for more power than the line can deliver. But take note that it's not always an issue of the electric utility not having adequate capacity - transformers can act like a choke, restricting how much total power gets through to your system. Perhaps the facility (or a neighbor on the same electric utility transmission line) added new equipment and increased the load beyond what the line could deliver. In isolated cases, maybe the facility added a motor with a long cable run, and the voltage drop in that circuit resulted in low voltage at that motor. Brief low-voltage conditions can also happen when someone starts a large load without notifying the power company, or when the power is shorted to ground or to another line. Even loose cable connections can cause low voltage. For an electric motor, torque changes as the square of the voltage applied. A 10% increase in voltage, for example, will boost torque 21% (1.1×1.1=1.21). Conversely, at 90% of rated voltage, the motor suffers a 19% reduction in torque (0.9×0.9=0.81). A more severe undervoltage condition, 20% below rated value, would reduce the motors torque to only 64% of rating (0.8×0.8 =.64). The effects are a 156% overload and catastrophic failure.


Can you change the generator into motor?

Yes. Certain types of motor. The best for this are DC motors with a permanent magnet field. DC motors with a field windings, need an excitation voltage to produce power. Simply rotate the motor, with an external force and DC current comes out of where you normally put power in. AC motors, induction motors, (squirrel cage type, typically used for domestic fans) are no good.

Is the current produced by a dc motor the same as the current given to it?

A motor uses electricity; it does not produce it. If you are somehow using a DC motor as a generator, then it will produce power equal to the input power minus the motor losses. If the input power is you spinning the rotor, the output power will be directly proportional to how much work you put into spinning the rotor.


How to repair window on 2000 cirrus it will not go up any more?

Generally with any power windows you need to check if you have power & ground to the motor. If you can put power to it, and it works, that tells you the motor is functioning. Then you need to replace the switch. If the motor doesn't work either up or down. Then the motor is bad.
