- Q: the motor came from a floof buffer it has a 3 gear planetary for tourq. I want to slow the moter down so I can bend rodiron
- Hi sorry but a lot more engineering is involved here the gearbox would not be the issue or slowing down the motor as a floor polisher has such a low powered motor. to bend metal requires a lot of torque especially cold and what sort of thickness is involved. hence why two things are usually done when bending metal a heat it up till it's cherry read hot makes it easier to shape and the second is done by hand as a blacksmith would do it. in industrial processes a hydraulic ram is used so it can control the amount of bend and increase in pressure can be done with a lager Ram. the reduction in motor speed with electric motors also tends to decrease the power in the torque of the motor. the most common method used with Ac motors is phase control which reduces speed and power and reduces power consumed as well.
- Q: i am restoring a old table saw. With the table saw came a westing house, a-c motor. At first i plugged in the motor and it just made a buzz noise.(didn't move) SO, i took of the the two cut wires it had, and plugged it in with the ground- on, well, the ground. it made the same noise then i pushed it and it went. yeaaaaa!!! buttttttttt i tryed it again and it went the wrong way???????? idk what to do. there have to be 4wires connect it to it, two i think go toelectricityy and two i don'tt know and there is a ground-whichh i have set up? sry is so long thanks for help.
- But the model number or more information about the motor is really needed to help you much more than that.
- Q: Whenever I have my AC on in my apartment, the furnace (which also has the fan for all the ventilation) makes a loud clanking noise. I reported it to the office and the guy said he thought the blower motor was out of sync. I didn't have time to ask him how to fix it. Anyone know how you would re-sync it?
- Try switching your wall thermostat fan switch to the on position. That is suppose to make your fan run 24/7. If it starts then your stat is not always making the connection in the auto position, and you need a new stat. If it still won't work, remove the cover of your furnace and trying spinning the motor by hand(w/ switch back in on). If it starts then you either have a dead spot in your motor windings, or a bad motor start capactior. If the motor is old your better off just replacing both. Unfortunately you can't go and get a motor just anywhere, but you can get a stat at a hardware store. If you need a motor check on the furnace manufacure's website for a parts dealer in your area.
- Q: An old folk told me that with his 18 years working experience, that increase in ambient temperature (above 40C) will cause an AC motor to lower its RPM......True?? Please advise.....
- There is absolutely no relation whatsoever, between the ambient temperature and the RPM of a motor. The RPM is decided only by the supply frequency and the number of poles in the motor. Just to quip, may be, when the ambient temperature goes very high and the load on the motor is also at rated levels, may be - just may be - the motor insulation may fail and it would come to a stop. That is the only way that I can think of any relation between the temperature and RPM. This is from my 26 years of experience in the field.
- Q: compare the efficiency of a DC motor against an AC motor.?
- What AC motor and what DC motor?
- Q: Specifically for a single phase AC induction motor...I'm having trouble wrapping my head around the concept of an overloaded motor drawing more current. Since current draw increases when electrical resistance decreases, then how does a motor with bad bearings increase current draw? I realize the motor needs to do a lot more work, but how does the extra mechanical resistance caused by bad bearings translate into a decrease in electrical resistance, which causes higher current draw? Is there a power equation factor here that I'm not taking into consideration?
- Hello Sanchez, When electrical energy is given to any motor, the mechanical output is always less than desired. This is because there are always some windage and frictional losses. You will understand from the following description: Motor input in stator can be divided into Stator Copper Iron losses and Rotor input. The rotor input can be further divided into Rotor Copper loss and Mechanical Power developed or Gross Rotor output. This Gross rotor output can be divided into Windage and friction loss and Rotor output or motor output. So in your case, even though the motor electrical resistance is not varying, but due to bad bearings, the windage and friction loss increases tremendously, leading to heating of motor. Since induction motor rotates at high speed, these losses will be very high, will lead to burning of motor, if the bearings are not replaced quickly.
- Q: I know that Watt, RPM Torque are connected each others, but, with the same RPM Watt, are there unordinary electric motors out there that have very higher torque than ordinary motors ( especially 220v 1 phase AC motors ) ?Can someone give me the website address about it ?
- Not okorder /
- Q: what will happen if dc is applied to ac motor?
- If you can reach the terminals on the other end, it'd be the same voltage as a 9V battery. However, city electrical systems are capable of generating a lot more current than 9V batteries, so slapping a wire across both terminals is still going to cause a sparkstorm.
- Q: i salvaged a 1.6kw motor from a vacuum cleaner-wishing to make it into a blower but i want to use the impeller as a propeller- i can do this by changing the running direction of the motorhowever i do not know how to do this-there are two wires leading to the motor brown and blue these wires are also connected to a capacitor in Parallel they lead straight from the plugi have tried disconnecting the capacitor to see if i can hand start the motor in the opposite direction-however even when the capacitor is disconnected the motor still runs in the same direction there are no more wires coming out of the motor and the 2 brushes are connected to the field wires(the electromagnets around the armature)- can the direction of the motor be changed
- Universal motors are usually series connected, meaning the armature and field are in series. You have to reverse the connections ro one of them, the armature or the field. The wiring will look like supply active, field in, field out, brush in (to armature), brush out, supply return. The capacitor is a electrical noise suppressor, just connected across the supply, or sometimes across the brushes. If it is shunt wound as you seem to describe (meaning the field is across the supply and so is the armature) then the solution is still the same, reverse one of them.
- Q: For a scissor lift, I need around +-102Watt to lift it, and while at lowest position before lifitng, it is around 9.08Nm torque required, and at highest position the speed is fastest where,447.8RPM.Now i do not know how to choose a DC motor and gear reduction ratio. because i cannot search any 120 watt catalogue have 10Nm stall torque. Can anyoe have any idea? or can we gear the motor torque over the motor stall torque at gearbox output? Thanks ...please help, and also the torque at output of gear box is gradually reducing,so RPM increasing? So what should be the ratio reduction of gear? From input motor speed to gear output speed..Which output speed location should i choose? Thanks
