Choose Best Pole-Slot to Increase Motor Speed

AI Thread Summary
To increase motor speed, the number of pole slots in a permanent magnet (PM) motor is not a determining factor if it has a commutator, as speed is primarily influenced by voltage. Reducing the number of turns on each pole while using thicker wire can help maintain copper weight and increase speed. Additionally, increasing the voltage and reducing the load can enhance performance. Specific details about the motor type and desired speed increase are crucial for tailored advice. Overall, understanding the motor's specifications and load conditions is essential for optimizing speed.

What is a PM motor ?
 
PM permanent magnet
 
If this is a DC motor with a commutator then speed is independent of the number of pole slots.
Unloaded speed is proportional to motor voltage. To increase speed, reduce the number of turns on each pole while thickening the wire to maintain the same weight of copper. Alternatively, increase the voltage and reduce the load.

What moves, the magnet or the wound armature? Is it a 500mW or 500kW motor?
You need to be more specific about the motor and load you have and how much faster you want it to go.
 

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...

Thread 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...

TL;DR Summary: Heard in the news about using sonar to locate the sub Hello : After the sinking of the ship near the Greek shores , carrying of alot of people , there was another accident that include 5 tourists and a submarine visiting the titanic , which went missing Some technical notes captured my attention, that there us few sonar devices are hearing sounds repeated every 30 seconds , but they are not able to locate the source Is it possible that the sound waves are reflecting from...
