Brushless Motor Controller Unit 40A ESC 2-3S Simonk
The 40A brushless electronic speed controller (ESC) is designed for use with sensorless brushless motors in a wide range of remote control applications, including aircraft, boats, and cars. This ESC provides steady and reliable power, ensuring smooth operation and precise throttle response.
Main Features
- Overheat Protection: Automatically reduces power output when high temperature is detected, preventing any damage.
- Low Voltage Cutoff: Protects LiPo batteries by cutting off power when voltage drops below safe limits.
- Throttle Range Calibration: Allows the ESC to align with your transmitter for smooth and precise throttle control.
- Motor Timing Adjustment: Precisely adjust motor timing to enhance performance for different motor setups and applications.
- Programmable Functions: Customize features like brake settings, battery type, and throttle response using a programming card (if supported).
Applications
- Remote Control Aircraft: Provides steady throttle control for small to medium-sized brushless motors in fixed-wing aircraft.
- Remote Control Boats: Ensures efficient power delivery and reliable performance in water.
- Remote Control Cars: Ideal for applications requiring high response speed and high durability.

FAQs
Is this ESC compatible with 3S LiPo batteries?Yes, it supports 2S and 3S LiPo batteries within a voltage range of 7.4V to 11.1V.
Can I use this electronic controller unit with a sensor-based motor?No, this electronic controller unit is specifically designed for brushless motors that do not have a sensor.
What happens if the temperature of the Electronic Controller Unit (ESC) rises?The overheat protection system automatically reduces power output to prevent damage.
How do I calibrate the throttle range?To calibrate, power on the Electronic Speed Controller (ESC) with the throttle stick on your transmitter set to maximum. Wait for confirmation signals, then move the throttle stick to the minimum and wait for activation tones.
Do I need a programming card to change settings?A programming card (if supported) helps simplify the configuration process, but settings can also be changed through throttle stick commands according to the ESC's firmware.
