Sensorless 3-Phase BLDC Core Specs:This V3 version high-speed driver works seamlessly with 3-phase DC brushless motors without Hall sensors (no Hall required for normal operation). It delivers 300W peak power (200W-250W rated), 5-50V wide operating voltage (60V max for emergency use), and 16A rated current (25A with forced cooling). Ideal for brushless motor setups in DIY projects, small tools, and industrial automation. 3-Signal Speed Control & Versatile Operation:Supports 3 adjustable speed modes: PWM signal (3-5V, 1kHz-10kHz), PLC 0-5V analog input, and 1-4.2V Hall throttle input—switch modes via the on-board button with LED indicator. The driver defaults to 0-5V mode (potentiometer set to minimum for all external modes), enabling precise speed regulation for different motor applications. Fast Acceleration & Safe Operation Guidelines:Features quick acceleration response but note: full-throttle startup at high voltage/power may cause high inrush current—leave operating margin and avoid hard direction reversal at full speed. Braking also creates strong impact; reduce speed throttle to 50% or below before braking/ reversing to prevent damage to power transistors and chips. Dual Protection & Low-Voltage Testing:Equipped with overcurrent, locked-rotor (current drops automatically after stall), and over-temperature protection (power halved in overheat). For initial wiring, always test with low voltage (5-50V) and low current first; avoid high-current/high-voltage testing during troubleshooting to protect the driver module. User-Friendly Design & Hassle-Free Setup:All ports use durable terminal blocks for easy wiring; comes with a standard heat sink and built-in speed potentiometer. The compact size (63×45×31mm) and lightweight (75g) make it easy to install in tight spaces—simply wire correctly, power on, and the controller is ready to use for your motor projects.
RioRand V3 300W 5-50V 3-Phase DC Brushless Motor Controller (Sensorless) is a reliable and high-performance driver designed exclusively for 3-phase DC brushless motors without Hall sensors, delivering stable speed control for a wide range of motor-driven applications. With a 5-50V wide operating voltage range (60V peak), 16A rated current (25A with forced cooling), and 300W peak power (200W-250W rated), this sensorless BLDC controller supports three precision speed adjustment modes: PWM signal input (3-5V amplitude, 1kHz-10kHz frequency), PLC 0-5V analog control, and 1-4.2V Hall throttle input—all switchable via the on-board button with clear LED feedback (factory default: 0-5V mode). Built with essential safety features including overcurrent protection, locked-rotor protection (auto current reduction), and over-temperature protection (50% power cut in overheat), it ensures long-lasting performance for your motors. The controller features user-centric design elements: terminal block ports for hassle-free wiring, a built-in speed potentiometer for manual adjustment, and a standard heat sink for efficient heat dissipation—making it ready to use right after proper wiring, with no complex setup required. Suitable for DIY robotics and model vehicles, small electric tools (grinders, drills), industrial automation equipment (conveyors, mixers), brushless water pumps, and cooling fans, this sensorless motor driver delivers fast acceleration response and smooth low-speed startup with strong torque, while safe operation guidelines (e.g., 50% speed reduction before braking/reversing, low-voltage initial testing) protect against damage to power components. Whether you’re a hobbyist building custom motor projects or a professional setting up industrial automation systems, this 3-phase BLDC controller provides reliable, precise, and cost-effective speed control for your sensorless brushless motor needs.
