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.

. . . and what is a Triac control?

How do you start a DC motor if there is no 3 point starter?
By the use of auto transformer and bridge rectifier we can start dc motor.
Is an AC generator can use AC motor and vice verso?
Are you planning to build a perpetual motion machine in which the power generated by an AC generator is used to run an AC motor which is used to run the same AC generator which provides it with power? Because that won't work. Yes, you can use a motor to generate electricity, and you can use electricity to run a motor, but the process is not 100% efficient and if you try to make it a closed loop, it will run down fairly quickly. So, what do we actually do? We use fuel to run an AC generator, or we use waterfalls or wind, or some other energy source, and then we use the power to run our motor.
How does a DC brushless motor work?
To state it simply, a DC brushless motor is not a DC motor. It is an AC motor with an inverter (or electronic commutator) on the front end to make the AC, so you can use a DC input.
Why motor rheostat kept minimum position generator rheostat maximum position?
the back emf increases so that high currents doesn't pass through the field windings
What will happen if field rheostat of dc shunt motor is kept at maximum position while starting?
First remember this rheostat is connected in series with the armature to increase the total resistance to limit the starting current, thus achieving max starting torque from the motor
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 .
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 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.
Why would an Ac blower not shut off on 2000 explorer?
My bet would be a bad rheostat.... It is located in the same vicinity as the blower motor itself and is what controls the speed of the blower motor. Kind of difficult to get at under the dash but not too bad. Will usually be one electrical connection to the blower motor and 2 screws to hold the rheostat in the mounting bracket.
Can rheostat run on AC current and DC current?
yes
Can you use AC in motor?
AC current is used in motors.
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
Fan works on ac or DC?
It depends on the motor. The fan is driven by an electric motor, and it can use a dc motor (as in a car) or an ac motor (as in a house). They are not interchangeable.
How do you drop the voltage of a 12v dc motor to slow it down?
Install a rheostat in series with the motor.
What are the applications of an AC motor?
Most of the motors are AC. Fans, Mixer, Industrial equipment, Aircon, vacuum cleaner, plenty of applications use AC motor
How do you start a DC motor if there is no 3 point starter?
By the use of auto transformer and bridge rectifier we can start dc motor.
