Here is a 4300KV sensored brushless motor installed into an NSR test car.

In case anyone wishes to build on this project as it progresses, I’ve added the pin-out for the 6-wire Hall sensor interface. Each of the three Hall sensors has a pull-down output transistor and therefore requires a 10k external pull-up resistor. As the motor rotates each sensor in turn switches between the two logic levels.

With this knowledge, the next step is to hook up the Texas Instruments development board. Nicely, this has SMD solder points for the three 10k pull-up resistors.

All, progressing to plan!

ps I’ve marked one pin as not used. This may prove to be a temperature sensor output - let’s see.
