Q: Is the single-phase carbon brush motor a direct current motor or an AC motor?: The role of the motor is to change the current direction of the DC motor and AC motor, the DC motor is to change the rotor's conductive coil, thereby changing the rotor magnetic pole. Thereby changing the motion of the motor. The carbon brush is used for motor commutator or slip ring, as sliding contact body import and export current, its thermal conductivity, and good lubrication performance, and has certain mechanical strength and direction of the spark of instinct. Almost all motors use carbon brush, which is an important component of the motor.

Q: Regarding electric motors with armatures and commutators and all that. With a split-ring commutator, it switches the direction of the current in a DC motor so that the armature can make full revolutions. So, if you take out the split-ring commutator, does that turn it into AC? And AC, by definition, changes current direction every half-turn, so why wouldn't AC make full revolutions too? Confusing..: yes, split ring makes it AC and half-turn refers to when you get to half a turn now the half of the ring that was connected to positive is going to be connected to negative so a switch occurs every half-turn, not actual physical turning of the part. Inside an AC motor, there is a coil and a magnetic field that turns it and it is very much the reverse of half ring. If you take out the half ring nothing can physically turn, but of course the force to turn is still there. You sound badly confused about it, you have to look at Lorentz force on a wire in a magnetic field, and you will see how depending on the direction of current, the wire is pushed up or down, because it is connected in a loop, it goes in a circle, half-way through, if the current direction doesn't change it will want to go back the opposite direction that it came from, but since the direction of the current changes thanks to the half ring, it will continue going in the same direction and makes a full round.

Q: Hi, i got one of those baby swings that run on two D batts. They last about 1 week. There must be a coverter i can buy at radio shack, or something right? What would it be called? Thanks :): A battery eliminator giving an output of 1 amp at 3v DC on full power should work. It has to have UL certification. May not be meant for outdoor use unless so specified. Linking this to the swing will mean wiring in an adapter. It is necessary to ensure that the connecting wire does not get entangled in the swing. Rechargeable batteries have a lesser output voltage. If the swing works with the lower voltage, you can get a pair with a charger.

Q: Or does it only work with a DC motor?: It is possible, but most such motors are small and will produce little power. There is also the question of variation in speed, which will change both the voltage and frequency of the generated power, rendering it unsuitable for domestic use without conditioning. Commercial wind turbines are designed to run at a constant speed; the blade angle can be changed to increase the power if the wind velocity increases.

Q: Could someone tell me what correlation between the slip (speed and frequency) and an AC motor, please?And is this relationship identical for every AC motor no matter the motor is brushless motor or SR motor? If I change the slip of an electric motor, what is also changed in this motor? current? torque?Are there any examples to say why and how to change the slip of a motor? Many thanks: The synchronous speed of an ac motor is determined by the number of poles a motor is wound for and the frequency of the current. RPM = Frequency x 60 x number of poles. AC motors must run a little less than synchronous speed. The difference in synchronous speed and actual no load speed is called slip.Some ac motors are made for speed control by externally changing the number of poles. Get the right hp motor and type for the application.

Q: In the old days they used a hewittic mercury-arc Rectifier, to convert electricity from ac to dc. I would love to know why they had to do this!: As far as I know, trolley bus motors are AC motors. AC power is much easier to handle than DC, which is why all the world's power grids are AC. But if you're transmitting power through an underwater cable, like we do through the Cook Strait cable here in NZ, you have to convert it to DC and back to AC at the other end. Two reasons. The cable behaves like a capacitor, with the conductor as one plate and the sea water as the other, and the insulation as a dielectric. AC power would leak away. Also the radiated power would interfere with navigation equipment on ships.

Q: where is the ac blow motor RESISTOR on a honda accord 04?: The blower motor transistor is located on the passenger side of the vehicle. It will have 2 screws holding it into the HVAC unit as well as a 4 wire connector running to it.

Q: I have an electric throttle with three wires ( black, red , green) and I want to know how to connect it to my electric motor and battery which both have only a black and red connector. How do I were it up so that I could control how fast the motor goes with the throttle .? Thank you .: Electric Throttle

Q: Would it be used in factories, Cars, some household appliances stuff like that: Each okorder /

Q: Motor PWM how to speed?: PWM speed control principle of AC motor and DC motor speed control principle is different, it is not through frequency modulation to adjust the motor speed, but by adjusting the driving voltage of the pulse width, and the circuit of some energy storage elements, change the delivery to the amplitude of the armature voltage, so as to achieve the purpose of changing the speed of DC motor. Its modulation mode is amplitude modulation.
