CIM motor driver for "shooter" application

[roystur44]

Here is a short video of our prototype shooter using a direct driven CIM. We controlled the speed using a Jag and a custom PWM circuit generator.

Startup to final speed was a few seconds. Ball compression was 2", 2 6 " KOP wheels

Here is a pwm circuit from Jameco that might do what you need

You can generate an RC Servo Signal using an old laptop computer.
