The “Max Regen Phase Current” value directly sets the peak braking torque of
the motor at full regen. If you want a strong braking effect, then set this to the
same value as the forward phase current limit. If the maximum braking force is
too intense, then reduce its value.
The following graph illustrates the interplay between motor phase current, battery
current, and motor output power for a typical setup. When riding at full throttle,
low speeds will be phase current limited, medium speeds will be battery current
limited, and high speeds will be limited by the voltage of your battery pack.
7.3 Tuning the Sensorless Self Start
Advanced Setup tab
If you are running a motor without hall sensors in sensorless mode, then you may
need to tweak the sensorless self start behaviour.
When a brushless motor is run
sensorless and started from a
complete stop, the motor controller
attempts to ramp up the motor’s rpm
to a minimum speed so that it can
latch onto the rotation (closed loop).
It does this by first injecting a static
current into the phase windings to
orient the motor into a known position.
