FQA60N60 high current motor driver
The DC Motor Speed Controller with FQA60N60 is an efficient and accurate speed controller for DC motors. FQA60N60 is a high-current N-channel MOSFET with the ability to support moderate and high power motors with low conduction losses. The circuit has PWM (Pulse Width Modulation) to make the voltage applied to the motor variable. The motor speed can be controlled accurately by regulation of the duty cycle. Optionally, an H-bridge is a bidirectional forward and reverse operation. The controller should be used in robotics, automation systems, conveyor belts, and DIY motor applications. It is inexpensive, dependable and easy to assemble on a PCB or a breadboard. The MOSFET must be properly safeguarded with proper flyback diodes and heatsinks to have stable operation.
Work / Installation (Inputs โ Outputs)
- Power Input โ DC motor supply voltage.
- FQA60N60 MOSFET โ Switches current to the motor based on PWM signal.
- PWM Control โ Adjust duty cycle to control motor speed.
- Optional H-Bridge โ Enables forward and reverse motion.
- Output โ Motor rotates at variable speed according to PWM input.

Testing & Final Adjustments
Once assembled, attach the motor and supply voltage. Connection of PWM input and step-by-step changes in the duty cycle to ensure seamless speed changes. Keep an eye on the FQA60N60 heat sink: heat sink optional. Check flyback diodes on each side of the motor to avoid a voltage spike. Test under different load conditions to ensure that speed is under control. Optimize the performance of the PWM and obtain the desired behaviour (smooth acceleration/deceleration). This is ensured by proper testing to ensure effective and reliable motor speed regulation that can be used on high-current applications in robotics or automation projects.
