SFOC 4in1 ESC 50A

What is SFOC?

FETtec SFOC (Simplified Field Oriented Control) is an innovative approach to control brushless three-phase motors, enhancing efficiency, lowering current and torque ripple, and improving response times. With FETtec SFOC, users can experience up to a 13% increase in efficiency and up to a 30% boost in acceleration, alongside other benefits such as stronger sensorless motor startups, reduced noise, and smoother motor operation.

Features:

• Controls 4 BLDC/PMSM motors using a single microcontroller

• STM32H56 ARM Cortex M33 @ 250 MHz

• 2-8S (6-34V) 40V MOSFETs

• Up to 50A per channel with good airflow (e.g., mounted in an open drone frame)

• USB-C

• FETtec SFOC motor control method

• Dshot 300 2400, OneWire, S2M

• Bidirectional Dshot with extended Dshot telemetry

• 64kHz and 128kHz motor PWM

• Up to 450k e rpm per channel

 As of 18.12.2024: Betaflight passthrough is supported up to version 4.5.0. Compatibility with later versions will be made available through future firmware updates.

Dimensions:

• Outer dimensions: 35 x 43.5 mm
• Mounting hole: 20 x 20 mm, M4
• Weight: 10g

Firmware:

• New FETtec SFOC Firmware
• FETtec Web GUI Configurator for Updates

Scope of Delievery:

• 1 x FETtec SFOC 4in1 ESC 50A

Recommendation:

Generally, we recommend using the provided capacitor and a FETtec Spike Absorber (when used with up to 6S).

When using an 8S setup, an appropriate flight controller or FC must be used, and an additional BEC may be required.
