Intro
- Brushless motor has electronics tronic commutation istead of brushes. It is more efficient and longer life than brushed.
- It is also simpler to build per see, as the complexity goes into the controller
- Lithium ion + brushless motor are state of art - [1]
BLDC Motor Controller
- 65x40 mm size, 300W, 24V, $20 - [2]
Batteries
- NiCd batteries are less environmentally friendly chemistry
- But Lithium is a scarce resource
- Comparisons n of bats - [3]
Geared Motor, not BLDC
Brushless (BLDC)
