DC PWM Motor Speed Controller - 50A Max - MX068
DC PWM Motor Speed
Controller - 50 AMP Max, Frequency Adjustable - MX068
Vary the speed of your
large DC motor (up to 50 Amps) with this heavy-duty circuit
without sacrificing torque. Gear
boxes can be costly and series resistors may cause stalling and overheating.
This circuit delivers the voltage to DC motors with pulses and the speed is controlled via pulse-width modulation
(PWM). This model also allows you to vary the frequency of the
- Power supply :
8-30 VDC via selectable jumper
- Load voltage :
8-30 VDC./50A. max.
- Motor speed :
Using PWM (Pulse With Modulation) for controlling motor speed.
LM324 and two IRF1404 MOSFETs with large heat sinks.
Spade connectors for easy
frequency : 100Hz & adjustable frequency 400Hz to 3Khz
- Can adjust the
motor speed from 0% to 100%.
- PCB dimension :
5.0" x 3.375" x 1.50"
- LED Power
- Fully assembled
and Tested - enclosure NOT included
(Need a Power Supply?)
This PWM DC motor controller
circuit can be used for generating hydrogen (Brown's gas), build your own fuel cell
station. More common uses include controlling DC motors in golf
carts, buggies, RC cars, robotics, DC hobby motors, toy DC motors, etc.
Additional cooling (fan cooling) may be required depending on current load and
