Active-Semi's HYDRA-X BLDC Head is an expansion board for the Hydra-X20 Body board, providing a

complete motor solution. Although developed to control tri-phase Brushless DC (BLDC) motors, the module

can be utilized to drive other motor topologies including, but not limited to, brushed DC motors.

The HYDRA-X BLDC Head has been designed to accommodate a robust power stage made of six power

MOSFETs rated at 60V and a maximum of 192A. The module contains all of the passive components

required to properly polarize and protect the switch elements.

This module was designed taking into consideration two BLDC control methodologies: Hall Sensor BLDC and

BEMF Detection sensorless. A connector is provided to connect hall sensor signals. In parallel to these

connections, the board provides phase output voltage dividers required to implement BEMF sensorless

algorithms. All that is required from the user is to download the pertinent firmware into the Hydra-X20 Body

board, and establish the respective motor connections.

Other resources made available to prospective developers are a potentiometer which could be used to control

motor speed, two push buttons, and a series of connectors which could be used to add external switches. A

placeholder for a thermistor was designed into the system allowing developers to add their own version of a

thermal protection directly interfaced at the FET block.
