PWM DC Motor Speed Controller 6-90VDC 15A

Control any DC brush motor from 6 V to 90 V with smooth, lossless speed regulation. This heavy-duty PWM controller uses high-frequency MOSFET switching to vary motor speed across a full 0–100% duty cycle — eliminating the heat waste of resistive control. With 15 A continuous current capacity and a direct-dial potentiometer for instant manual adjustment, it's the fastest way to add professional variable-speed control to any project.

🔹 Pro Tip

💡 This controller works with most 12 V, 24 V, 36 V, and 48 V DC brush motors. For higher current applications above 12 A, mount to an aluminium heatsink or chassis plate for optimal thermal performance. Compatible with treadmill motors for DIY CNC router spindle builds.

⚠️ Note: Always ensure proper heat dissipation and correct voltage configuration before powering connected devices.
