Closed Loop Speed Controller For
3-Phase Brushless DC Motor
MP-3T Package
OMC506
Description:
The OMC506 is an integrated, high density, three phase
Brushless DC (BLDC) motor, speed controller housed in a
MP-3Tpackage. The OMC506 contains the power, driver
and control electronics to adjust timing functions and speed
control loop parameters to optimize the controller for each
application. The electronics contained in the OMC506 are
assembled using mixed process technologies: surface
mount components on a printed circuit board and chip &
wire on an Insulated Metal Substrate.This combination
offers small size, excellent thermal characteristics and
electrically isolated heat sink.
