Siemens 1PQ High Low Voltage AC Motor

Q: I have a 1995 GMC Safari. The AC works intermittently and I think it is the blower resistor for the motor. Today it was working, but there was steam or smoke coming out of the vents. Could this be the blower motor going bad, or part of the resistor problem?: It's more likely the blower motor it might be causing your resistor pack to over heat and ruin it to. the blower is under the hood I think with the resistor pack close by. If you got my first reply I'm sorry I miss read your vehicle and thought you had a Sierra pickup.

Q: how does a synchronous ac motor work? please help!!!: They're also called stepper motors. Here ya go!

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: when i did some research on ebay to buy motors, AC motors were usually rated for 120 volts, or 240 volts, while most DC motors were only rated for like, 24 or 50 volts. Why? Is AC better?: I don't think you can justify any global conclusion about the quality of motors based on the observation that 'most' AC motors are rated 120 or 240 v, while most DC motors are rated at lower voltages. In fact, I might hypothesize a totally different global conclusion. First observation, most DC motors are intended for application where they are integrated into a piece of electronic equipment, for example, a computer. Therefore, the motor must be designed to be powered from the DC power supply associated with that equipment. AC motors, on the other hand, may be intended for use in either stand alone applications or applications in equipment that are fundamentally AC systems, for example, HVAC systems. And in these applications, the controls and motors typically operate on the input line voltage, usually 120 or 240 v, and not on some lower voltage derived within the equipment. Therefore, one might speculate that the reason that you see more DC motors listed on e-Bay is that there are more folks out there tinkering with electronic equipment that uses DC power supplies, and where the motors therefore have to be DC.

Q: Why is it better to use a DC motor rather than a AC motor?: Wouldn't that depend on your application, power demand, power availability, etc? If you're running a toy remote controlled car, you'd get better efficiency with a DC motor, but if you're turning a ceiling fan, the heat loss in converting AC line power to DC to run the motor would kill your efficiency and an AC motor would be better.

Q: Can a DC series motor operated on an AC supply?: An universal AC/DC motor is series wound, so a series DC motor will probably run on AC, but if it was designed specifically as a DC motor rather than a universal, performance might suffer.

Q: a motor that runs on ac and dc?: Mostly, if they have a lot of power in a small package (especially for rotary speed), but are used only sporadically. They often are a bit noisy. If they have a speed control, then they could be universal.

Q: i wont to make my slide door to open and close with out use my hand and i wont the electronic map to make itthank for all: The answer is you can't unless the motor is designed to operate in both directions. This is due to the location and connection of the starting coil of the motor. TexMav
