    Tips: What is an electronic speed controller?

    The electronic Speed Controller (ESC) is an important part of the electric propulsion system hardware. It acts like the brain of the system, telling the motor how fast to run based on data signals it receives from the throttle controller.

    For smaller applications such as drones and RC vehicles, the controller is named "ESC," while for larger manufacturing applications it might be called an electronic control unit, inverter, or motor controller.

    It performed very well
    I picked up this ESC for a brushless motor project, and it’s been performing great so far. The response is smooth and stable, and I really like that it supports multiple communication methods — makes integration with my control system much easier.

    It runs smoothly
    Just installed this on my custom e-bike build. Handles 20S power like a champ and the regenerative braking is super smooth. No issues after 50  miles.
