Flipsky FSESC 75450 Speed ​​Controller, 14-84V, 4-20S, 450A, with water cooled

The Flipsky FSESC 75450 Water-Cooled is a high-power electronic speed controller (ESC) based on the VESC platform, designed to control BLDC motors in high-current applications. It supports an operating voltage of 14–84V (4–20S), a continuous current of up to 450A, and a peak current of up to 1200A.

The controller features an STM32F405 Cortex-M4 168MHz processor and supports both BLDC and FOC control modes. It is compatible with Hall, ABI, AS5047, and AS5048A sensors and also supports sensorless operation.

Its aluminum housing with an integrated water-cooling system ensures efficient heat dissipation under heavy loads. The controller supports programming and configuration via the VESC Tool and offers a wide range of interfaces: USB, CAN, UART, SPI, and IIC.

It includes adjustable protection systems against overcurrent, undervoltage, overvoltage, and overheating of both the MOSFETs and the motor.

Regenerative braking support allows for the utilization of energy generated by the motor during braking.
