Q:Compare and contrast the AC generator and the DC electric motor?

D.c motor converts electrical energy into mechanical energy while A.c generator coverts mechanical energy into electrical energy. D.C motor works on the principal of left hand rule while A.C generator works on the principle of faraday s law of electromagnet induction. Current carrying coil rotates b/w the poles of magnet.. A.c: simple coil rotates b/w the poles of the magnet

Q:Where the fuse for the fan motorblower located on my 96 bonneville because i bough a new blower motor and its still not working

follow the blower motors wire to a module. That is the no# 1 thing to go bad before the blower motor.

Q:What is the neutral point of an alternating current motor? How to determine whether the neutral point leads to?

AC motor star connection, only the neutral point, as shown in the figure, the neutral point of the motor is connected with lead wire, 4 wire, three fire zero, zero line to neutral point.

Q:Is it possible that i could start a fire or something? I took an old plug and connecting the motor wires to it, then i hooked the plug to the mains socket, it starts quite a big spark when it turns on, but should it be safe? even if the plug is well covered in its insulation?

You can always connect the motor to the mains, but ONLY through a AC Motor Starter of proper rating matching the motor. Ordinary switches and plug tops are not designed to handle high inductive loads. Since the motor is an inductive load, switching it on with an ordinary switch or plug will definitely create a spark. The spark is caused due to arcing between the contacts (due to back emf or inductive kickback) can be a potential shock hazard to the user. If the spark latches on to something combustible, then there is also a fire hazard. If you use it regularly, the spark will erode the contacts leading to failure of switch/plug So use a properly rated AC Motor Starter which is designed to avoid the above problem. An additional bonus is that the starter will have a thermal relay which will protect your motor and electrical wiring in case of overload due to load, bearing failure, rotor jam etc.

Q:Is household sewing machine good for AC motor or direct current motor?

There are special motors, and the DC motor market is rare

Q:Brushless DC motor is AC motor or DC motor, why?

The DC motor only has no brush and commutator. It should be inside to check the rotor position through the Holzer sensor, make the drive circuit turn over, and make sure the motor turn in one direction

Q:What will happen if i supply ac current To a dc motor?

DC autos function in basic terms whilst dc modern is given.If we alter the polarity shaft will run in opposite direction.whilst u provide Alternating modern, created magnetic field retains it in a null factor ensuing the coil to get heated up and burned.

Q:Whats the difference between induction motor and synchronous motor?

Synchronous okorder /

Q:I am trying to figure out how to make an bench grinder that has an AC motor with a DC power supply with out buying an expensive inverter. This is for class project and we are on a budget.

Can you tell us something more about the motor ? I think if we knew what kind of AC motor it is we could know about the construction and that will make it easier for us to think of a way to run it on DC supply. I think you might need a Brush and Slip ring assembly to be mounted on the same shaft as the motor so that the DC gets Converted in to AC.

Q:Specifically, I want two questions answered:1.How does a single-phase permanent split capacitor AC induction motor work? (I know it involves the phase difference between a capacitor's current and voltage, but I need some more detail).2. All the fans in my house with this type of motor have 3 speeds. How do they achieve these three speeds? I've taken apart the motors and found 4 pairs of coils (i.e. 8 coils in total)?

yes,it is a single phase induction motor. its speed is controlled by regulators which have different resistances in them. there are 4 or 5 resistances in the increasing order kept inside the regulator box. when we turn the speed ,we change the resistances.when the fan is off,there is no current flowing hence it does not work. when we change the speed to 1, the resistance is internally set to the highest of all resistances. gradually when u move on speed to 2,3,4.. the resistance value decreases. at full-speed the fan is at no resistance. that means it consumes all the current flowing.As resistance reduces the current flow, so is the power affected thereby the speed of the fan is controlled. internally when u change the speed, the connections are accordingly changed.
