- Q: I replaced a capactor on my blower motor with the same value as recommended on the nameplate. 5uF, 370VAC. It opened up after about a day, then I replaced it with another one and it did the same thing. I checked the value of the cap before installing and it was correct. The motor is rated at 9A, and I am getting a current draw of less than that.
- It sounds like a problem with the load on the motor to me. The Cap is only for starting,you could have a start winding going bad or something is holding the motor back at startup, or centirfigal switch that cuts out Cap is defective.
- Q: Hello, I own a 2001 Mercury Mountaineer (8cyl) which has been having some AC issues lately.A few months back, the AC would only blow if switched on the high position. When switched to low or somewhere in the middle, it would turn off.Now, the AC does not turn on at all - except for rare instances when it will turn on - and blow on high.When i turn the AC dial, i hear a clicking coming from the glove box area, which makes me believe that it may be the actuator. Is it possible it may be the actuator or the blower motor?Thanks!
- blower resistor or dirty connection find the bower motor follow wires to the resistor check in and out if possible
- Q: i have a d903 electric motor on my ac unit and it wont start on its own. if you start it by hand it runs but i?
- The capacitor for starting the motor may be bad. Capacitors store electricity, in this case they discharge when the motor is turned on to give it an extra boost of electricity. Some motors also have an internal start winding and if this winding burns out then the motor won't start on its own. I recommend that you have a tech look at it, capacitors still carry a lethal amount of current even when everything is turned off and the electricity supply disconnected.
- Q: I'm looking for the websites about the design and theory of ac/dc motor.Thanks!
- I think you will like this site...it covers both...
- Q: I have this 12V 7Amps DC Dry Cell Battery please see image below
- Battery power would not last long enough.You would need 2, one on charge. Cheaper using mains power.
- Q: The motor is out of a dryer (240 VAC) so there is lint build-up in the motor's grease. The casing seems to be a cast iron that has been... connected... not welded, not screwed together. I see no way to get the case open to pull it apart. I can get it working properly for about 24 hours using generous amounts of WD-40, but the motor builds up some physical resistance after this time. I feel I need to clean the contacts, and relubricate the motor. I can see the contacts as the case only holds everything together, and does not fully enshroud the windings. What can I use to clean the motor without dissasembling it further, or how can I dissasemble the case (if you have come across this before you know what I mean). I am an apprentice electrician so I already understand the safty concerns of fixing an appliance.
- Thinking way back, we used to spray the windings and electrical contacts with a chemical that used to come in fire extinguishers. I don't even think it's available any more as the fumes in a closed room have killed. (Couple of kids having a squirt fight). The chemical was Carbon Tetrachloride. The trouble is, it would dissolve lubricating grease too! I would seriously think of replacing the motor. Sounds as if you already have it out. I found a motor to match a burned out one by taking it to an old guy (must have been 80+) working out of his basement and he looked at it and said that one on the top shelf should do it. It had the same specs and was a half horsepower stronger. (It is still pulling the fumes out of a restaurant 10 years later). Good Luck !
- Q: Hey guys! I need your help.... I know just one point that DC motor can control speed even with load but AC motor can't. I want more points...... could u help me???? It would be gr8 if u could tell me the name of the site from where i can get some info. about this.......Thankyou in advance!
- Usually, DC have a higher degree of efficiency compared to some AC motors...like shade pole versions (like fan motors). Plus like the previous statements...DC are easily controlled but are a more complicated piece of machinery. AC motors are simpler construction, but need special drives to control speeds. Plus DC's with brushes tend to be limited by the brushes themselves. They wear out. AC motors with a good set of ball bearings practically last forever.
- Q: Can the motor be mounted safely in the middle of the rear axle? In other words, is it possible to get rid of the gears inside a car (transmission and differential) and put the power straight to the wheels? Wouldn't that minimize power losses and further increase torque?
- On hybrid vehicals they put the elec motor between the eng and transmission. On the front of the trans. If you dont want a trans ,then just mount the elec motor where the trans is and connect it to the drive shaft. Do this on a car that has rear wheel drive like a S-10 blazer.
- Q: Braking principle of 220V alternating current motor
- 1. the basic structure of three-phase asynchronous motorThe construction of three-phase induction motor is also divided into two parts: stator and rotor.(1) stator:The stator is the fixed part of the motor, which is used to produce rotating magnetic field. It is mainly composed of stator core, stator winding and frame.(2) rotor:The rotor is the main part of the rotor. There are two kinds of rotor, squirrel cage and wound rotor. Grasp their respective characteristics and differences. The squirrel cage type motor used for medium and small power (100k or less) is simple in structure, reliable in operation and convenient in operation and maintenance. Winding type can improve startup performance and speed regulation. The air gap between stator and rotor will affect the performance of the motor. The general air gap thickness is between 0.2-1.5mm.
- Q: Can anyone give me the torque equations for AC synchronous motor and generator
- Torque=Kt*I, where Kt is the torque constant and I is the current. It's that simple.
