Restore power and smooth throttle responsiveness to your electric bicycle, scooter, or light utility vehicle with the Universal DC Brushed Motor Controller Series. Engineered for standard 2-wire brushed DC motors, this compact replacement module provides reliable speed regulation, low failure rates, and efficient power transfer across 24V, 36V, and 48V system setups.
Encased in a durable aluminum alloy housing ($83 \times 65 \times 37\text{ mm}$ physical footprint) designed for optimal passive heat dissipation, this controller protects internal circuitry against thermal stress and road vibration. Featuring a standard $1.0\text{V to }4.0\text{V}$ speed regulator signal input, it pairs seamlessly with standard thumb throttles, twist grips, and brake cut-off switches.
⚠️ System Voltage & Motor Compatibility Notice
IMPORTANT FITMENT GUIDELINES:
Brushed Motor Requirement: Built strictly for 2-wire DC brushed motors. This unit is NOT compatible with 3-phase brushless (BLDC) motors.
Voltage Matching: Select the precise operating voltage (24V, 36V, or 48V) required by your battery pack and controller setup.
Under-Voltage Cut-Off (24V Variant): Features an integrated $20 \pm 0.5\text{V}$ low-voltage cutoff to prevent deep discharge damage to 24V lead-acid or lithium battery packs.
🚀 Key High-Performance Features
-
High-Efficiency Aluminum Alloy Shell: Deep-grooved heat sink casing ensures quick heat dissipation during extended climbs and high-load operation.
-
Smooth Speed Regulation: Operates across a standard $1\text{–}4\text{V}$ speed governor signal range for fine throttle control and predictable power delivery.
-
Integrated Battery Protection: Automatic under-voltage cutoff safeguards your battery bank against over-discharge and permanent capacity loss.
-
Color-Coded Wire Harness: Features labeled, high-temperature resistant lead wires for power, motor, throttle, ignition key switch, brake cut-off, charge port, and indicator light.
-
Multi-Power Handling: Available in 250W, 350W, 500W, and 800W wattage configurations to support standard commuter e-bikes, mobility scooters, and electric ride-ons.
