Driving A2212 brushless motors, the HW30A 30A Brushless Motor ESC Speed Controller manages power distribution for drones and RC aircraft. Between 5.6V and 16.8V, this controller maintains a 30A continuous current flow. Integrated safety protocols stop accidental motor rotation during battery connection.
Key Features
- Safety Arming System: Motor won't rotate on power-up despite throttle position. Prevents injury during battery linkage.
- Battery Protection: Automatic cell detection for 2-3S LiPo and 5-12 cell NiMH. Cuts power to prevent permanent battery cell damage.
- BEC Output: Linear 5V/2A supply for receivers and flight controllers. Powers secondary electronics without extra battery weight.
- 40A Peak Capacity: Sustains 40A bursts for 10 seconds without circuit failure. Resists heat damage during high-torque maneuvers in humid air.
- Signal Compatibility: Accepts PWM signals from 50Hz to 432Hz. Works with most standard flight controllers and Arduino boards.
Frequently Asked Questions
Can I use 3S LiPo with 30A ESC?
This controller supports 2S and 3S LiPo configurations. It manages input voltages between 5.6V and 16.8V safely.
How to calibrate 30A ESC with Arduino?
Connect the signal wire to a PWM pin and send a 2000ms pulse followed by 1000ms. This sets the throttle range within the 50-432Hz signal rate.
