Headway Research PWM202 Spinner

Headway Reasearch PWM202 Spinner

The PWM202 controller can drive the BD5 motor to its full 373 kW (1/2 horsepower) capability. The top speed of the BD5 motor is 5,000 rpm. The motor is a dc servo motor with a vacuum-thru-the -shaft design for vacuum chucks and potentially a substrate lifter, working through the motor shaft. The acceleration/deceleration ramp is adjustable over a range of approximately 0.5 to 4.0 seconds from zero to max speed. The three sequence timers can be set to one of two ranges: 0.1 seconds to 99.9 seconds or 1 second to 999 seconds! The sequence is: Timer 1 at Speed 1, then Timer 2 at speed 2, then Timer 3 at Speed 3. A +24 vdc output from each timer is available externally, for actuating dispense functions or other peripheral devices during the active time of that timer. The PWM202 can control simple 1 and 2 fluid type accessory dispensers.
