At Artica, we had a request to link MAXMSP to an industrial motor for an artistic installation witch we will speak about at another time.
This motor is a true beast, and since we have never worked with such a thing we decided to ask for help to our electronics guru David Palma.
The motor controller:
David developed an electronic circuit to simulate a PWM analog output from 0 to 10v (originally it gives 0 to 5v), and another circuit to switch motors direction, both circuits were assembled on a shield and connected to the motor controller.
The first circuit is a transducer:
And this is the switch circuit that tell to the motor controller wich direction the motor will spin:
Then he builded an Arduino shield:
And the final part was the Max patch that send the direction states and the PWM values to the Arduino:
And this is the result:
