How Many Turns for a 48V 40-60A eBike Motor Using 10AWG Wire?

Click For Summary
SUMMARY

The discussion focuses on designing a 48V 40-60A eBike motor using 200C 10AWG magnet wire and a 24-pole stator core. The user seeks assistance in calculating the number of turns required for the coils, which will influence the final design of the stator core and motor diameter. The user is considering coil configurations of either 3 or 4 turns per pole, with wire lengths of 4.5 inches and 6 inches respectively. Accurate calculations are essential for optimizing the motor's performance and efficiency.

PREREQUISITES
  • Understanding of electric motor design principles
  • Familiarity with magnet wire specifications, specifically 200C 10AWG
  • Knowledge of stator core configurations and dimensions

It's been like 3 or 4 years since I've built an electric motor & I've forgotten mostly everything and need some help getting this worked out for those that don't mind.

I'm trying to build a 48V 40-60A eBike motor. I'm using 200C 10AWG Magnet Wire.

I have a 24 pole stator core. The stator core will be around 1.5" thick with a 5" outer diameter. I can expand it to around 8" diameter & 5" or so thicker and wider if needed though. I'll likely be doing coils over every 3(1" coil, 4.5" per turn wire length) or 4(1.5" coil, 6" per turn wire length), for 8 or 6 total poles.

I'm trying to figure out how many turns I'm going to need so I can determine the final stator core design & motor diameter and all.

Can someone help me with this?

I can provide any other information needed, thanks!
