For clarity, I’ve mentioned that my earlier brushless motor experiments with slot cars demonstrated they run smoothly at low, medium and high speeds using Hall sensored brushless motors.

However, to date these trials have used standard R/C equipment (i.e. a Spekrum transmitter and receiver) in combination with a sensored brushless ESC and motor.

It’s not too surprising this combination runs well as it’s effectively a radio controlled car that picks up power, and is guided by, the rails and slot respectively. That said, this hardware was quite bulky and barely fitted inside a 1/32 scale slot car.

The next stage is to replace the receiver with a digital decoder and to replace the ESC with a sensored brushless driver board. This should provide a far more compact solution.

With the help of a Texas Instruments motor driver development board, I hope to interrogate and characterise the 5wire/6wire Hall sensor interface of the specific brands of brushless motors I am using. Once this is completed the design of a highly compact brushless motor driver module can begin :)
