F1 BLDC Motor Add-On Board
The BLDC Motor add-on is a simple development accessory that plugs directly into the F1 Evaluation Platform (DM164130-1) or F1 LV Evaluation Platform (DM164130-5) and incorporates all the components necessary to implement Brushless DC motor control.
The BLDC add-on (DM164130-2) allows you to drive virtually most sensorless three-phase brushless DC motors used in consumer electronics, ranging from small HVAC applications to complex media reading/writing drives. The add-on is shipped together with the ebm-papst BLDC motor, to which it connects through a ribbon cable to a special connector on the board (J5). Alternatively, any other 5-12V BLDC motor can be used by hooking it up through the J2 connector.
The BLDC add-on uses a typical three half-bridges control configuration suitable for three-phase BLDC motors, using six MOSFETS commanded through six bipolar transistors. Sensorless control is done in the software without any other external components.
Key Applications: Consumer electronics, ranging from small HVAC applications to complex media reading/writing drives.
