This Mindsets motor speed controller replicates the electronics used in electric drills and will control the speed of all mindsets motors – including the very large MM54. The controller works from 3v to 12v and has a maximum ouput current of 5 amps – sufficient for most prototyping applications. Simply connect a potentiometer (e.g. 10K), motor and power supply.
• Two 1.2V rechargeable batteries will not provide sufficient voltage.
• Below 4.5V the FET may not fully ‘turn on’. This limits the current to the motor, however, the output is still capable of powering small DC motors.
