- Q: Tore an AC motor out of an OLD SCHOOL cassette tape changer. It has three leads, red, blue, yellow... Tried all conbonations with a 120v whip. Some did nothing others made it humm... That's about it... Wondering how I can find out how to drive this baby???
- ya motor could very well be a stepping motor run by a chip that supplies a pulsed supply around the 3 wires which it reverses by reversing the pulses similar to a lightchaser if you wish to go into this further try googling this chip- SAA 1027
- Q: How can we test servo motor ? Is the testing of a servo motor is different from other types of AC DC motors ?thanks
- Any motor with a positioning system is a servo motor. Having said that there are motors specially designed with high torque to function as servos, for which different testing procedures must be applied. DC motors are best to work as servos. .
- Q: Why does the AC motor turn?Do I feel that the coil is not in a steady state?
- Because the child is short circuit loop ends conductor short circuit, in the role of the induced EMF, will produce the rotor conductor with Induction EMF direction basic consistent induced current. The rotor load by electromagnetic force in the stator magnetic conductor (the role of the direction of the force with the left hand dingze judge). The electromagnetic force electromagnetic torque the rotor shaft to drive the rotor to rotate along the rotating direction of the magnetic field.
- 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: I have a 98 BMW 7 series. The AC Blower needs to be replaced. Does the mechanic have to remove the dashboard to install a new one? Or can the replacement motor be installed from the front engine area
- how do you know its not the resistor or something more simple?
- Q: AC motor gear variable or frequency conversion good?What are the disadvantages?
- The frequency converter is the electric energy control device that transforms the power frequency power to another frequency by the on-off function of the power semiconductor device. We now use the converter mainly adopts the AC-DC-AC mode (VVVF inverter or variable frequency vector control), the first AC power into DC power supply through the rectifier, then the AC power into DC power supply frequency and voltage can be controlled by the supply of electric motive. The frequency converter circuit is usually composed of rectifier, intermediate DC link, inverter and control of 4 parts. The rectifier is a three-phase bridge controlled rectifier, and the inverter is IGBT three-phase bridge inverter, and the output is PWM waveform. The intermediate DC link is filter, DC energy storage and buffer reactive power.
- Q: related to electric goodshow much is thge consuption of 1/4 hp motor
- This is probably a split phase capacitor start motor where all or part of the capacitance used in starting is switched out once it is running, and that would be the first place I would have looked as you have done. The rcd rating is about 12 times the full load current and this would not protect it against an overload, so it sounds like there is a fault in the motor or the feed to the motor and the only way to find it is to take the circuit apart and do insulation checks on each bit. Intermittent faults like this are hard to find as when a test is carried out the fault doesn't always show.
- Q: Sorry that no one could read my mind in answering this question last time. The answers were not to the point. quot;To maintain same power at lesser voltage you need more currentquot;. Well does the motor know what power it has to deliver? Isnt the power delivered determined by voltage that is applied? It is an open loop circuit right? So what is the factor that induces the motor to draw more current at lesser voltage? Please.....
- it somewhat is thoroughly linear, extra modern is had to do the same paintings with much less voltage, and vice-versa. With AC the situation is extra laid low with the fee sensor circuits, which will immediately call for extra modern to maintain shaft velocity. If the present headroom isn't there the motor can lag right into a at the back of schedule phasing state and right this moment overheat and cook dinner the windings.
- Q: HELLO, I WANT TO CONVERT ABOVE CONFIGURE MOTOR 1440 RPM TO 120 RPM ONLY BY ELECTRICAL OR ELECTRONICS SOLUTION. PLEASE ANY ONE PROVIDE ME SOLUTION AND CIRCUIT DIAGRAM FOR THAT. I DONT WANT VARIABLE SPEED CONTROLLER. I JUST MAKE ONLY ONE CONTROL OF SPEED AT TIME. SO PLEASE GIVE ME LOGIC AND CIRCUIT LOGIC ALSO.
- That is not going to work. It sounds like an induction motor. The speed is controlled by the frequency of the supply. To get a speed less than 1/10 of normal, you would need to generate a frequency less than 5 Hz. If you did that, the efficiency of the motor would be horrible. Even if you managed with that, you would still have problems. Most A.C. single phase motors rated at more than a few tens of watts use a 'centrifugal switch' to disconnect the starting windings when the motor is running. It certainly would not operate at that speed. Your motor would cook. Sorry.
- Q: i want the difference in working operation at the rotor side as at synchronous motor rotor feeded by D.C current but at induction by A.C
- Synchronous AC motors run at a speed fixed by the input line frequency. Typically 60 Hz in the USA. Run a clock with the sync motor from the USA in England and it runs slow because they use 50Hz. Asynchronous motors run at whatever free-run speed they feel like, and slow under load. A DC wound hand-drill is such a motor, runs pretty fast till you start drilling, then it slows down. A synchronous motor will develop maximum power at its' designed speed, try to slow it down and it puts out more torque. Slow it down by overload, it doesn't create more power, it just creates more heat. An Async motor creates highest torque at stall speed, least torque as it approaches maximum speed.
