Q: how are the torques in ac motors controlled, is the relationship between torque and armature current still applies?? T= k(flux) Ia .... ? does this formula still applies in ac motors or only to dc?? please explain
The torque equation applies for DC motors and synchronous AC motors, but no induction motors.
Q: will it affect the defroster or heater if i cut the ac belt?
if you cut the ac belt the only thing it will affect is the power steering that's assuming the engine has two belts, the other belt will work with the water pump and alternator ***warning*** if the engine has only one belt you cant cut it the defroster and heater can be affected because the ac compressor work with the system but if you dont uses the compressor with the heater it will work good but not as is suposse to work
Q: I know what a DC is. I think i'm sure about what an AC motor is, But what is an AC/DC motor and why is it different from an AC motor?
Well, there isn't much of a difference but an AC motor must be plugged into a wall outlet for example. A DC motor can run on a battery such as a car battery.
Q: I am using the motor on a toy car.
It takes less electronic parts to control a DC motor than an AC motor. Also DC motors have higher RPM's than AC motors. The rpm of a AC motor is depended on the frequency of the voltage and the number of poles. The rpm of a DC motor is depended on the current and voltage applied to it.
Q: I was wondering how much would it be to replace the heater blower motor on my car and also how much the labor costs would be?.
If you have a socket wrench set, do it yourself. Both the blower motor/fan assembly and the resistor-pack assembly are super-easy to replace on 97 Escorts (underneath the instrument panel, passenger side). First thing is remove the blower motor/fan assembly from your vehicle. Get a 9v battery and a couple of wires and pass current into the motor leads to see if it works. (Don't worry about damaging anything if hookup wrong--there's nothing sensitive inside the motor/fan assembly.) If it works, then buy a new resistor-pack from a Ford Dealer. (Early 1997's did have a problem with the resistor-pack prematurely failing due to moisture buildup. This was fixed by adding a rubber sealing gasket.) If it's the blower/motor fan that's the problem, then buy one from a junkyard. There's no need to buy brand new unless you're planning on keeping the vehicle for 10 years.
Q: AC motor speed regulator
The other is called magnetic transmission, and the cost performance is similar to that of the converter. But the principle is different. It is characterized by long life and little maintenance. It has been applied in the speed regulation of large motors. AC motor speed controller is simple and can be used for limiting the buck, governor as the electric fan, the speed control method is simple, but the load characteristics of the motor is very poor, only suitable for small motor load and stable situation.
Q: g. the switch or what
Blower motor.
Q: Can someone please explain to me the difference between an AC motor and a DC motor, but in a way that a non-technical person can understand? Not saying it has to be completely dumbed down - just want to have the light bulb go off. Thanks.
Well AC, or Alternating Current motors are more efficient than DC or direct current. Both motors work by basically positive and negative current chasing itself in a circle which never catches up to itself so the motors turn. In AC, polyphase or three phase motors this becomes more efficient because you need lower current to do the same thing a DC motor does which requires more voltage to push it. But in a basic sense DC motors are good because you can control the speed of them better than AC. You will find DC motors on things like rock crushers, car crushers etc. where there is a slow but constant speed needed despite the load. A DC motor may turn a conveyor belt at 2 rpm's but when you add rock or a crushing apparatus you will still get that 2 rpm despite the load. A lot of your home appliances ironically run on DC motors too. Now overload it then you will have problems but that is it's basic uses today. AC motors you will find in factories because they have a faster startup speed and when you use the three phase motors they are just more efficient. There is a type called a squirrel cage and then you can imagine the squirrel in the cage moving the rotor that chases the cage or the stator but never really goes end over end when doing so. That is the same principle of magnetism and voltage chasing current inside a DC or an AC motor but each are suited for uses where one or the other may not be as good given the circumstance or the operation you want to control.
Q: ok i have a 95 nissan pickup and my ac went out the other day i can still feel cold coming out the vent the blower motor ant comming on i straight wired it 2 the battery and it works could my resister be bad does the resister have any thing to do wit the ground on the blower motor
Keep in mind even with a bad resistor you should ALWAYS have HI mode......because HI bypasses the resistor and supplies battery voltage to the blower. Unplug resistor and check for power from the fan speed switch if you don't see any action you need a switch or have a bad fuse.
Q: my 94 plymouth sundance is not blowing air on ac,heat or defrost changed blower motor still doesn't work?
Did you replace the blower inside the house or the fan on the outside? Check compressor if its running and line is frosting up. If so need freon if not check start capacitor for condensor fan and compressor.
