EvaDrive range of motor-mounted stepper drives and controllers

The EvaDrive range of Australian-designed motor-mounted stepper drives and controllers are available as either a packaged stepper motor/driver/encoder assembly or as a separate PCB mount stepper driver module. This technology gives economical and reliable bipolar stepper motors servo-like performance with full torque control even at high speed and all without the usual stepper motor heat issues.

Available in sizes 17, 23 and 34, they can be supplied with or without motors. Standard encoder resolution is 16,384 counts or users can run it open loop as a 512 micro-stepper drive with accuracy to 102,400 steps per revolution.

The standard evaluation kit includes a motor with integral drive, cables, power supply and PC interface software. The GUI includes torque, position and velocity gauges, configurable CRO and PID loop control, as well programming of the four onboard I/O.

The open architecture design allows for OEM customisation by replacing the top cover with the EvaDuino PCB card and writing custom functions in C (up to 120 Kb). This card has extra I/O including PWM outputs, analog inputs, SPI and I2C, and has a dedicated processor which will accept and run Arduino programs.  Programs can run stand-alone or with a host computer. Custom hardware solutions such as embedded logic or special connectors can also be supplied for OEM’s to create their own application driven solution.
