Motor Poles and RPM Explained

Motor RPM is directly proportional to motor poles and frequency.

Didn't realize i was coming here for this but I was looking for answers what pops up .., never fails .... thanks Tim

[aarongrady]

Really helpful. Thank you. From a 3rd year electrical apprentice.

[gabrielkatoka]

minor addition:
Less poles - high speed - low torque.
More poles - low speed - high torque.

Thanks nice explanation of poles. I have a question, I came across TFO-FK 2p 200V motor. Its got 3 wires coming out of it. Not sure how to hook it up as I've got single phase 220v and 3 phase 220v supply available.

One thought to add, speed of an ac motor inversely proportional to no of poles, and directly proportional to frequency, your video time 3:06 supports this.

Do you know if a mo-6226 motor could be used for an ebike?

[sorinionescu]

Hello, so if I want to make a generator from a three-phase motor that has 8 poles, then the number of magnets I have to put on the rotor is 24 magnets? (12N and 12S)

I have a scooter hub motor that is 15 pole pair? and a fardriver ND 84530 the problem is the driver is 14 or 16 pole pair settings only (so in the middle ) . I think the motor gets a little hot and self disconnects the hall sensor? does this pole count make the motor run hot ? when it works it is a most wonderful scooter for about 30 seconds . then have to wait for it to cool down to reset . any thoughts would be very welcome ! thanks !

please can you tell me refrigerator compressor coil .. how many poles thank you

[carlosquispegaldos]

Clearly explained, thank you for the work you put in the video

I have disassembled multiple Baldor motors; both 1800 and 3600 rpm and I noticed that that the 3600 rpms use a lot more wire in the windings ( which take more space) and as a consequence the rotor's diameter has to be smaller. On the 1800 rpm motors the rotor is bigger and there's less wire use for the windings. Could anybody explain why? I'm just curious as to why that is the case. Each comparison was made using motors being the same HP and having the same physical size.

Simple and clear explanation sir, would be great if you can add some animation how Hz and pole influence speed.

[aijazshaikh]

Thanks friend, very good and very simple way to explain abut
Speed o motor with pole relation.

[ersamatskefski]

Can you please answer me if this applies to DC motors as well as AC Motors? I just cant find the answer

[alexandres]

the poles of a motor is the analogy of a gearbox transmission to more poles more torque and less speed while the electrical power remains constant.

I have a question how many number of turn is used in a 2hp 2 pole motor as in main winding

[refaelisrael]

hi, very good and clear explanation for the motor, i have a question about the rpm of generator, how i calculate the speed (rpm) of generator with 10 pole ?

[IceyJunior]

So the poles are actually indicating how many sets of stator coils it have? Not the rotor coils right?

[CasamTheAnimator]

You could actually make the motor turn in both directions, by adding a dial, if you connect negative to negative and positive to positive, the motor will turn in the correct direction, if you connect negative to positive and positive to negative, the motor will turn in another direction.

[wondersofcreation]

If I lower the RPM will it affect the Hz ? Say for instance, we use 50hz electricity which is 3000rpm and the motor am using to turn the alternator am working with is 1800rpm and so the alternator is not generating power, what should I do please ?
