capteur
Actuellement, de nombreux fabricants proposent des systèmes Brushless
pour les voitures RC. Concernant les systèmes avec capteurs, le nombre de
fabricants est plus limité. Les systèmes à capteur/sonde sont
autorisés dans certains pays depuis plusieurs mois et le seront dans
d'autres lors des mois à venir. La réglementation nomme quelques
fabricants tels que LRP-Reedy, NOSRAM et TEAM NOVAK pour les plus connus.
Neanmoins,
d'autres fabricants, tel Schulze, propose des variateurs compatibles avec
les moteurs à capteur.
Concentrons-nous
sur les systèmes Brushless "légaux". Comme mentionné,
LRP-Reedy, NOSRAM et TEAM NOVAK sont les principaux fabricants de ces
systèmes. Le variateur et le moteur fonctionnent en couple, les
fabricants ayant développés leurs moteurs en adéquation avec leurs
variateurs. Le nombre de variateur est limité et quelques moteurs
fonctionnent avec chaque variateur.
Voici quelques variateurs (tous les modèles ne sont pas listés)

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. |
