Description
Closed Loop Speed Controller For 3-phase Brushless Dc Motor Mp-3t Package
Manufacturer
International Rectifier Corp.
Datasheet
Closed Loop Speed Controller For
3-Phase Brushless DC Motor
MP-3T Package
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.

... MC33039 Closed Loop Brushless Motor Adapter I.C. to provide direct duty cycle control of the motor speed. The OMC506 provides two quadrant speed control via an analog signal applied to the Vspeed ( pin22 ) input. The OMC506 is selected for 60/120 degree hall sensor spacing. The commutation truth table for the OMC506 is shown in Table 1 ...

Page 4

... Motor commutation and speed control are derived from the Hall effect sensor signals provided from the motor. The signals are provided as inputs to the OMC506 (pins 29, 30 and 31). The amplitude of the sensor signals must be limited, by the user, to +6.2V to insure proper operation of the module. ...

... This power module integrates all the functions necessary to control a DC brushless motor. The design of the OMC506 is flexible enough to be customized for various applications while still maintaining a turn-key solution to the end user. Finally, the MP310, as other industrial packages from International Rectifier, makes the user’ ...
