Features:

Motor Parameters

Input Signal

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.
