When using a swamp cooler can you use a rheostat to control the motor speed?

A: A swamp cooler uses water flow to control temperatures as the water flow increases the transfer function increases. So yes it will effect the temperature. but for humans at the same time more water in the air will effect our perspiration and cooling in effect basically it will reach an equilibrium whereby more water will not cool us any further. A 70 degrees and 100 % humidity is hotter then 85 degrees dry heat

Can you use a rheostat on ac motor?
Yes you can use a rheostat to control the speed of an ac motor as long as it is correctly sized (power). A better way would be to use a triac control.
What is the importance of speed control of DC motor in industrial applications?
The speed control of the DC motor is important because its speed can be changed over a wide variety of simple methods which is not possible in an AC motor.
Speed control of motor using SCR?
An SCR chip is commonly used to control the speed of a motor. The speed is controlled using an AC circuit and phase angles.
What are convectional and non convectional methods of speed control of a induction motor?
The flux control method is the convectional and the non-convectional method of speed control of an induction motor.
What in slip speed control?
slip speed control refers to induction machines s=(synchronous speed-motor speed)/synchronous speed by varying slip the machine can be either be operate in generated mode or motor mode
Can a rheostat be used to control speed on a capacitor run motor?
No. If you attempt to reduce the voltage to a cap start motor by using a rheostat, you can destroy the motor.
Can you use a rheostat on ac motor?
Yes you can use a rheostat to control the speed of an ac motor as long as it is correctly sized (power). A better way would be to use a triac control.
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 .
How do you change the speed of a motor in a circuit?
By varying the Resistance to the motor. These Devices are called RHEOSTAT'S
Can a volume control switch act as a variable control switch for a AC fan motor or a similar motor household only?
Putting a rheostat in series with a motor is not necessarily the best way to control the motor speed. The rheostat works by converting what electricity would have been going to the motor into heat. An audio rheostat would need to be sized appropriately. Putting a rheostat in series with a synchronous motor that is found in some fans is not particularly good, either. Since the motor is phase-locked with the alternating current would simply make the motor turn with less power at the same speed until it starts 'tripping over itself'. That leads to overheating. A better option is to use a solid-state motor controller. That delivers full voltage to the motor but rapidly cycles on and off. As you turn the controller up the power is more on than off.
What are 2 mathod of speed regulation in DC motor?
The speed of a dc motor can be regulated by the following means:By varying the supply voltage and byUsing a variable rheostat.
How regulator controls the speed of AC motor?
the motor should only rotate in a rated speed,if the speed is more than rated speed then the motor will be damaged........to control the speed of motor a rheostat should be connected to the field side of motor......by variying the rheostat we can control the speed of motor......
What is vf speed control?
It is used for sensorless motor control. With vf speed control u can control speed of any induction motor.

How do you control the speed of a pneumatic motor?
The speed is varied by throttling the air flow into the motor.
