DC motor speed controller — for DC 7–70 V Key benefits Wide voltage compatibility: works with DC supply voltages from 7 V to 70 V, so a single controller fits a broad range of DC motor systems. Precise speed control: lets you adjust motor RPM to match load and application requirements, improving control and operational flexibility. Simplifies system design: centralizes motor speed adjustment without changing the motor or power source. Core functions and attributes Function: speed controller for DC motors (Drehzahlregler für Gleichstrommotoren). Applicable voltage range: DC 7–70 V. Compatibility: suitable for DC motors that operate within the specified voltage range. Performance: provides adjustable motor speed control across the full 7–70 V input range. Typical applications (practical scenarios) Small electric vehicles and e-bikes with drivetrain motors rated within 7–70 V where variable speed is needed. Light industrial equipment and conveyors that use DC motors and require adjustable speed for different process conditions. Robotics, automation, and DIY projects where precise control of DC motor speed improves motion accuracy and system responsiveness. Why customers need this product Avoids the need for multiple controllers by covering a large voltage span. Enables fine-tuning of motor speed to optimize performance, efficiency, and task-specific behavior. Makes it easier to adapt one motor system to different loads or operating conditions without replacing hardware. Compatibility note Use with DC motors whose ratings fall inside the DC 7–70 V range. Check your motor and power supply specifications to confirm compatibility before installation.
