DC motor operate much like incandescent lamps. Servo motors respond to digital pulses representing a position or angle of rotation.
The speed of DC motors operating within the voltage and current limits of the dimmer are easily controlled by DMX channels. For direction control, a second dimmer output can be used to flip a relay that reverses the DC motor connectors – polarity of power directly controls spin direction.
In a different mode, RC4 Series 3 dimmers can control the position of “hobby” servo motors. This kind of servo is frequently used in puppetry to control blinking eyes, wiggling ears, and mouth movements. Large servo motors are what move the head elements of Scar in Disney’s The Lion King.
Motor control is easy with RC4 dimmers, whether you need to spin a whirlygig or pull a pin to trigger a gag – no wireless dimmer is as versatile, right out of the box, as an RC4 Series 3 dimmer.
