A while back I demonstrated a two part decoder which is SSD compatible and which has a high current drive module for brushed motors.

This approach is now being applied to a sensored brushless motor solution.

The same core microcontroller module as used above for the brushed solution will also be used for the brushless motor solution. In this case the same four-wire interface will be connected to an electronic driver module for the sensored brushless motor. The four wires provide power and motor/brake signals.

The brushless driver module can be driven directly by the four wire interface and, as would be expected, this module has a three wire output to drive the motor. In addition it has the five wire sensor interface for the three Hall rotational position sensors.

The initial approach will use an off-the-shelf driver module which measures approx 33mm x 33mm i.e. quite large.

Once this approach is proven at track level a full custom pcb using a DRV10970 IC will be attempted.

A fun project for summer 2025.

Photos to follow as this project takes shape.
