motor
BLDC AC
19. Comparison-6
Internal controller
• Stable signal because motor and
controller is close
• Very easy installation for end user
• Cost down in extension cable only
need 2 core or 3 core
• Warranty motor and controller
both if failed
• Need another monitor if working
with floating switch for tank
External controller
• Un-stable signal limited the extension
cable between controller and motor
• Installation need professional guys
• High cost in extension cable of 4 core
• Could seperatly warranty motor or
controlelr if failed
• Have floationg switch teminal in
controller
• Have erro code dispaly
