Siemens Original 1PQ Series AC Motor

Q: plz tell me basic difference b/c ac and dc machine in terms of thier working principle?: There are two main types of electric motors. There are direct current or DC and alternating current or AC motors. The reference of DC or AC refers to how the electrical current is transferred through and from the motor. Difference between AC and DC motor somewhat lies in the name as their name reflect their working style. Electric Motor:- It is an electrical device which convert the electrical energy into the mechanical energy. It may be broadly classified into the two types AC motor and the DC motor depending on the type of input used. DC Motors:- A direct current or DC motor, converts electrical energy into mechanical energy and works on Direct current(DC).Among DC motors, there are shunt-wound, series- wound, compound- wound and permanent magnet motors. Dc motors come in two general types. They can have brushes or be brushless. AC Motors:- A current or AC motor, converts electrical energy into mechanical energy and works on alternate current (AC).AC also comes in two type. They can be two phase or three phase.

Q: What is the problem with my ac, my condenser fan motor will not turn but the compressor comes on?: When you ask us questions on here we can answer them better if we know what kind of car ,year ,and engine size ,and make . but on the fan not coming on it might be the fan relay , or the fuse , or the high temp switch . and move the fan blade back and forth and make sure it ant locked up and make a jumper wire long enough to go from the fan to the fan mot er and make sure the mot er work es , if so make sure you get 12-v to the high psi switch if not that is the problem

Q: I have a AC motor that I wanted to hook up to a small go cart its 115 dc volts and 4.8 amps what controller thingy (that makes it speed up and slow down) should I use?: the question maybe should read.... how do I get 115 dc volts AC motor? is that alternating current.... or air conditioner? might need a long extension cable?

Q: will it affect the defroster or heater if i cut the ac belt?: I would suspect that the belt that controls the AC compressor is also controlling the power steering pump and possibly alternator. You would need to make sure the compressor has an indiviual drive belt. It would be easier to remove the fuse for the A/C system which should allow you to still have the use of the heater, etc.

Q: ac motors vs dc motors for electric car?: The ac motor used less wicky math than the dc motor to look cool in their science fare, ac motor. But you get that just running a current in a circle works great?

Q: What is the purpose of the encoder and how can you tell if it is working properly. thanks: Picture encoder as reporting device. (Watch dog) It can be use to report things like number of revolutions, position of the armature, speed, acceleration etc. this information can be used in may different ways, very often it is used as so called feedback control. It works like this; you give a command to the motor to go specific number of revolutions, encoder is watching what motor dose and confirms to the control device if it actually happens. Search Google or yahoo on steeper motors or servo motors to learn more.

Q: So, my old blower motor started smoking, and sparking, I took it in, and bought a new one, the guy also sold me a new capacator with it, and hooked it up for me... BUT I'm confused which wires go where. I took pictures..: Is the orange wire on the capacitor in your picture attached to the top of the contactor? It is hard to tell. If it is, then on the new motor, the 2 separate wires that go to the capacitor (probably both brown), go to the capacitor, the black wire on the new motor goes to the same place where the original black wire went on the relay, and the white wire goes to the terminal where that orange wire comes off of the contactor. I hope this makes sense. A lot of older motors were 3 wire.

Q: It is the chiller plant pump and we were trying to run the pump,unfortunately the motor was damaged.so what could have happened to this motor.: If the motor is filled with water, don't run it. Disassemble the motor and oven bake until the moisture is evaporated. If the motor is immersed while operating, the motor may be burnt. Megger test between line to ground and between two lines. If the insulation resistance is below 1 megohm, the motor may be burnt.

Q: why choke or du/dt filter is used with vvvf drive of ac. motors?: Vvvf Drives

Q: Comparison of AC motor and direct current motor: Disadvantages of AC motor1. the starting and regulating speed of AC motor is poorAlternating current motor can be divided into synchronous motor and asynchronous motor according to speed.
