Looking for a compact, efficient, and reliable DC motor controller for your next project? Whether it’s an EV conversion, RC boat, industrial fan, or a DIY robotics platform, our versatile DC Motor Controller offers plug & play convenience with professional-grade features.

Adaptive Control for Any Setup

Enjoy total control with support for multiple input methods: standard potentiometer, hall throttle (0.8–4.2V), joystick mode, direct PWM (0–95%), RC PWM signal (1.5ms ±1ms), or full serial communication via TX/RX for advanced customization. This controller fits any control scenario, from manual analog setups to automated systems.

Built-in Safety & Current Limiting

Prevent overload and extend the life of your motor and controller with our smart current limit function. Set the continuous current from 0–50A, with peak support up to 100A. The controller will automatically limit output to protect your system from damage and heat-related issues.

Stay Cool Under Pressure

The Crocodile FR5050 50V DC Motor Speed Controller 100A includes overheat protection (70°C / 158°F) to avoid damage under heavy use. For maximum performance, we recommend using a heatsink when operating at high output. Though compact and efficient, active cooling ensures stable performance and long-term reliability.

Energy Recovery with Regenerative Braking

Equipped with 4-quadrant motor control, this controller supports regenerative braking in both directions. Recover energy on deceleration and feed it back into your battery—ideal for electric vehicles, automated transport, or eco-friendly builds.
