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

You need a series motor like the one use for drill. By changing the stator coil direction, AC series motor can change its rotation. A DPDT relay can do this task. Use this motor to rotate a gear to control door either open or close. Limit switch installs on both end to stop the door at fully close and fully open position. A reset control is also require to restart the task.

Q:not asking for a inverter

You can. Just go buy an inverter. Connect the inverter between the DC battery and the AC motor. Voila.

Q:can thet be replaced, and how do you do it?

I can’t imagine anyone trying to replace the bearings / sleeves in an electric motor. If you hire it done the cost would be prohibitive if you try to do it yourself with limited knowledge the chances of being successful are very remote. Remove the motor and take it to grangers or any place that has replacement motors in your area and they can match it up Cap and all. Your done ! enough said.

Q:Preferably an ev gray design

I think DC would be easier than AC. Some motors are available from McMaster-Carr, W.W. Grainger, etc. You don't need as much horsepower from electric motors as you do from internal combustion engines.

Q:Can i convert it to batterry if i can't find a motor and what size battery operated motor should i buy

You should be able to find a replacement AC motor (110V, 60 Hz for use in the US) at an electrical supply store, a clock shop, a hobby supply shop, or on-line. You could even go to a major retailer like Walmart and just get a regular (cheap) AC-operated mantle clock or something similar, and then use the guts of that to replace the defective one in your grandfather clock. Make sure the old grandfather clock hands fit on the new movement, or just replace the hands when you replace the movement. As far as using a DC (battery operated) movement goes, certainly you can do that. Again, go to a hobby supply store or a major retailer and buy a battery-operated clock. Remove the DC motorized movement and put it in your grandfather clock. The required battery size is specified by the movement itself. Typically a medium to large DC clock movement requires one AA or C battery, although some movements may require 2 each AA batteries or even a special battery, such as a Type N. Either way (replacing the AC motor with another similar type AC motor, or replacing the whole AC movement with a DC one), you should be fine.

Q:the actual speed of a six pole a.c motor operating from a 50hz supply with a 6% slip is what?how do i work this out please

Synchronous Speed of an AC Motor (Ns) = 120 x f / P where 120 is a constant, f the frequency and P the number of poles. In your case, Ns = (120 x 50)/6 = 1000 RPM Slip is the difference between synchronous speed and actual speed. So 6 % slip means (6 / 100) x 1000 = 60 RPM So actual speed is 1000 - 60 = 940 RPM Good luck

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 through the front engine bay?

check the fire wall to see if the blower motor is . it is easy to replace

Q:I have a 13 year old Bryant Heat Pump with the compressor outside on the ground and the air handler in the garage. Its been a reliable unit so far and was wondering if I should replace the compressor fan motor since it gets well over 100 degrees here in the summer months. The old one is working fine buts its 13 years old and I was wondering if some preventative maintenance would be a good idea here.

If you wanted to do something, I would order the OEM motor and have it handy should you need it. OEM motors always last longer and if it goes bad a tech will in most cases use a generic motor. But still no reason to do this, if you have a fan motor and the compressor goes then you are stuck with the fan motor, So I would just stick to make sure it is serviced once or twice a year if you want to spend some money.

Q:A sinlge phase AC motor is needed to lift up vertically a load of 150kg to 200kg using chain and gear. Please help.

Depends on how fast you want to lift it. With the right gears a tiny motor will do the job, although it may take hours.

Q:where is the blower motor(ac/heater) located? how do i replace it?

most are under dash inside or behind heat unit box first check your fuse or switches some not so hard to get to other than a lot of small screws you might be able to find by typing into search box how to replace blower or how to replace heater fan 1993 honda might find it by going to autozonewebsite and type in your car info and name of part they have many how to's as well... its about a 4.5 hour job to replace
