Where to find DC & BLCD applications and what are the technical requirements for low voltage?


What means 24V for low voltage industrial applications?

Devices for 24V industrial application must have: n a nominal operating voltage up to 36V n Rule of thumbs: 24 +/- 30% = [16 ; 32]V

Main differences between a DC & a BLDC motor

n  Less complex software: cost optimized MCU

n  Less components: only four MOSFETs

n  DC Motor Price

n  No brushes – no mechanical wear out

n  More torque per weight & watt

n  Reduced noise n  Less power consumption n  Higher efficiency
