Hi,
I looking for some help, I have a device that when conditions are met it turns on a small motor to provide vibration feedback. The current feedback is very weak and I would like to add a much larger motor with speed controller to give adjustable feedback.
Would it be safe to add a relay replacing the motor that would turn on the replacement motor. I have measured the voltage across the motor when activated at 3.8 volts dc.
As-is
PCB - Motor
New
PCB - Relay - 12v psu - Speed controller - Motor
If this looks ok can someone recommend a relay
Thanks
