 The DMC 60 is an electronic speed controller designed for driving brushed DC motors. It utilizes synchronous rectification to efficiently produce a variable output voltage that’s controlled by a PWM Input Signal. This makes the DMC 60 ideal for use in robotics applications, including FIRST Robotics Competition.  The DMC 60 is an electronic speed controller designed for driving brushed DC motors.

-The Digilent Motor Controller’s (DMC1 and DMC2) continuously monitor the input voltage. If the input voltage falls below 5.75 Volts (+/- 2%) for 5 or more seconds, then the output duty cycle will be set to 0% and an under voltage fault will be signaled. The output will remain disabled until the fault is cleared (3 seconds), at which point it may be re-enabled if the under-voltage condition is no longer present.+The DMC 60 continuously monitors the input voltage.
