III - Brushless System
2 - Sensored Brushless Systems
Those days, many manufactures provide brushless system for RC cars.
Concerning the sensored brushless system, the number of manufacturer is
quite reduced. The point here is competition. The sensored system
is allowed in racing for the past year in some countries and will be allow
in others the coming year. The rules name some equipments including
LRP-Reedy, NOSRAM and TEAM NOVAK for the well known.
Nevertheless,
others manufacturers, as Schulze, have ESC compatible with sensored motor.
We will focus
on "legal" brushless system here. As say previously, LRP-Reedy,
NOSRAM and TEAM NOVAK are the main manufacturers of those systems. The ESC
and the motor work tougher in that case, manufacturers had developed
motors in adequation with their ESC. The number of ESC is limited and some
motors run with each ESC.
The sensored brushless ESC available are: (short list, more exist)

Mode 1: Brushed/Brushless
and Forward/Brake/Reverse or Forward/Brake selection.
Mode 2: Punch Control, with
three engine maps: Sportsman, for brushless operation limited
to 24, 000 RPM, Low Grip, using LRP’s intelligent current
limiting system, and Modified, for unlimited RPM and linear
throttle operation.
Mode 3: Initial Brake
with four levels:
- Linear
- Smooth
- Medium
- Aggressive.
Allows the driver to adjust the feel of his brakes.
Mode 4: Automatic Brake,
adjustable in four levels:
- No auto-brake
- Smooth auto-braking
- Medium auto-braking
- Aggressive auto-braking.
This feature is especially important when using brushless
motors, as it enables you to closely simulate the feel of
driving a conventional brushed motor (with its inherent “drag”
brake action) when coasting in neutral. |
