UH300 brushless motor controller for drone
Features
1. Support dual throttle (CAN digital throtle +PWM analog throttle) control, priority CAN digital throttle control.
2. Quick response. it will take only 0.6 seconds from starting motor to full speed running.
3. Good compatibility and stability with special control algorithm for disc motors.
4. Synchronous flow technology, with better throttle linearity and drive efficiency. Further, during deceleration.
5. The ESC will automatically recycle energy and charge the battery reversely for extending flight time.
6. Has RPM, error signal output interface.
7. With CAN communication interface, it can communicate with flight control in real time.
8. Easy to install, it can be installed normally or reversed.
Protection Function
1.Short Circuit Protection
When the ESC detects and triggers short circuit protection, it will turn off the output. lt will automatically resume and restart after 100ms.
2.Stalling Protection
Motor stall wil trigger stalling protection. ESC will resume after making throttle zero and powering again.
3.Voltage Protection
Once checking voltage is less than 40V or more than 120V, ESC will alarm and will not start up motor,etc.
4.Temperature Protection
During fight, if the temperature of the ESC is higher than 125°C, it will generate a fault signal and start reducing the output power to 50% of the maximum value. lf the temperature continues to rise to 140°C the ESC will turn off the output, and the normal output will not be restored until the throttle setting is reset to zero,etc.
5.Throttle Loss Protection
When the detected throttle signal is lost for more than 2 seconds, the ESC will automatically shut down. After the throttle signal is restored, the ESC will work again.
6.Start Protection
If the throttle is accelerated for 10 seconds but the motor fails to start, the ESC will turn off the output. in this case, you need to reset the throttle to zero, and then accelerate the throttle to return to normal.

Chris D. –
I’ve been flying drones for years, and the UH300 ESC is by far one of the most efficient controllers I’ve used. Stable current delivery, zero signal delay, and great durability.
Remin –
The UH300 ESC provides excellent throttle response and stable output under heavy load. The build quality is solid, and it runs cool even during long flights. It’s ideal for professional UAV setups requiring consistent performance and precise control.
