What potentiometer do you need to use so that a 1.5-3 volt DC motor is off on one extreme and full speed at the other extreme?

Radio Shacks 25 ohm rheostat works very well to the point where on the slow end, you have to give it a kick start if you turn on the power when it is on that side. If it is already running, it will continue to run (no load) at the low end.

How the servo potentiometer works?
A potentiometer is another name for a variable resister used for voltage dividing. Potentiometers have three tabs on them The two outer most tabs have the full resistance of the device across them. The center tab is connected to the wiper that slides across the surface of the resister. A voltage is applied to the two outside tabs on the potentiometer. A voltage of your choosing will appear across either the left tab to the center wiper tab or from the right tab and the center wiper tab. A potentiometer of this type is used to control the speed output of variable frequency drives. A 10K potentiometer has 10VDC applied across the two outside tabs If the drive sees the full 10 volts it allows the drive to go to full output and the motor will run at full speed. With the potentiometer's center tab wiper at half position a voltage of 5 VDC will appear to the drive. When the drive sees the 5 volts it tells the drive to go to half speed output and the motor will run at half speed. This potentiometer is linear so no matter where the wiper is positioned, the motor speed will follow the potentiometer settings from 1% right up to 100%

What does no load speed on a electric motor mean?
Generally a motor drives some equipment, it could be a fan, or a pump, connected to motor's shaft. The speed of the motor when no equipment is connected to its shaft is known as no load speed.
What Pokemon learn extreme speed?
1.I think Garchomp can 2. Arcanine learns it at level 49 and then Lucario can learn it too.
In Pokemon Which strikes first quick attack or Extreme speed?
the Pokemon with the higher speed stat ,I think.
How do you you control the speed of a dc motor?
A Potentiometer, an adjustable resistor, is connected between the power source and the motor. An AC motor would use a Rheostat .

A potentiometer is used for?
A potentiometer is a type of position sensor. They are used to measure displacement in any direction. Linear potentiometers linearly measure displacement and rotary potentiometers measure rotational displacement. Also known as a Potmeter or Pot, it consists of a resistive element called the track and a sliding contact called the wiper internally where end terminals are attached to the resistive element. They are used to accurately measure voltage and help achieve a variable voltage from a fixed-voltage source. Common Examples of Potentiometers are: Measuring Position on a gaming joystick Controlling audio equipment using volume controls
If you increase or decrease the frequency what effect on electrical machin?
If you're talking about an electric motor, increasing the frequency will increase the speed of rotation of the motor, and decreasing the frequency will decrease the speed of rotation of the motor. The other way of controlling a motor is to control the current; increasing the current increases speed, decreasing current decreases speed.
What is the speed of DC series motor at no load?
No load speed is the speed that the motor run when it has no load, i.e., the motor is separated from the engine, that speed is than greater than the rated speed, because the rated speed is the speed whwn the motor are linked to the load and it is the full load.
Why is a synchronous speed motor considered a constant speed motor?
synchronous motor is a constant speed motor because it will only run at a synchronous speed or not at all.the speed can be changed by changiing the frequency only ns=120f/p
Can scysor learn extreme speed at on pokemon platinum?
No, Scizor is incapable of learning Extreme Speed in Pokemon Platinum.
What are the advantages of speed control of DC motor using micro-controller when compared to other?
This motor is able to work from the battery. The speed is less complicated to use and you do not need much voltage.
