Hello,
From what I have learned in this forum, there are two interesting technologies of motor for our purpose (e-bike):
- dc motor. The motor controller "feed it" with a constant Voltage.
- The BLDC / Brushless motor, which needs a much more complicated controller. This motor is 3-phases and can have Hall sensors
For my purpose, I'm looking for a motor of about 1500W.
I am learning to make a sensored BLDC motor controller
I can find Hub motors at about 100-150 €/$
Here comes my question:
I'd like to find a small (diameter 12cm length: 15cm maximum)
either
-a DC motor
-a sensored BLDC
But, I can't find cheaper than Hub motors (or even same price)
Why?
I mean Hub motors are very specific, how can they be so cheap/ how can "plug and play" motor be so expensive.
Have a nice day
