DC Motor Speed Controller Module operating on 4.5–35V DC with PWM control (20 kHz, 1–100% duty cycle), up to 5A / 90W output. Compact 30×26×14mm module with potentiometer knob for smooth, stepless speed adjustment — ideal for makers and engineers.

 

The DC Motor Speed Controller Module (4.5–35V) is a compact, potentiometer-based PWM speed controller designed for brushed DC motors. Operating across a wide 4.5V–35V input range and delivering up to 5A continuous output current (90W max), it suits a broad range of motors used in robotics, automation, fan control, and DIY projects. The ultra-low standby quiescent current of just 7µA makes it energy-efficient during idle periods. With a fixed PWM frequency of 20 kHz — above the audible range — motor operation remains virtually silent.

Κύρια Χαρακτηριστικά / Key Features

  • Wide Input Voltage (4.5V–35V): Compatible with common battery packs, bench supplies, and automotive sources → versatile across projects
  • High Output Current up to 5A / 90W: Drives medium-power DC motors without external amplification → ready-to-use out of the box
  • Full PWM Range 1%–100%: Precise, stepless speed control from near-stop to full speed → smooth motor response
  • 20 kHz PWM Frequency: Above the human hearing threshold → silent, noise-free operation
  • Ultra-Low Standby Current (7µA): Negligible idle power draw → battery-friendly designs
  • Compact Form Factor (30×26×14mm): Fits tight enclosures and custom PCB layouts → space-saving integration
  • Integrated Potentiometer Knob: Direct manual speed adjustment without any microcontroller → standalone operation

Typical Applications

  • Robotics & RC Vehicles: Precise drive-motor speed control for differential-drive robots or RC car builds
  • Fan Speed Control: Quiet, stepless regulation of 12V or 24V DC cooling fans in enclosures
  • DIY Lathes & CNC Spindles: Manual speed tuning for small benchtop motors up to 35V
  • Conveyor & Automation Rigs: Reliable low-cost speed regulation in maker automation projects
  • Solar / Battery-Powered Systems: Low standby drain makes it suitable for off-grid pump or actuator control

FAQ

Q: Can I connect this module directly to 220V AC mains?
A: No. The input must be DC only. Connecting to AC mains will permanently damage or destroy the module.

Q: What happens if I reverse the power supply polarity?
A: Reverse polarity may damage the controller. Always double-check positive (+) and negative (−) terminals before powering on. Motor lead polarity can be swapped freely to reverse motor direction.

⚠ Safety Warnings:
  • Input must be DC only — never connect to AC mains (e.g. 220V). Doing so will burn the module.
  • Do not reverse the DC supply polarity — this may permanently damage the controller.
  • To reverse motor direction, swap the motor output leads (not the supply leads).
  • Ensure the load does not exceed 5A / 90W continuous rating.
