The EZQuad Servo was designed to allow the rapid implementation of multi- axis stepper motor solutions in products requiring automation.

Measuring only 2.25” x 2.25” X 1.0” (57mm x 57mm X 25mm), the fully intelligent servo motor Controller + Drivers runs 4 fully independent Brushed or BLDC servo motors. Operating from a 7V to 40V supply, the controller regulates to any motor voltage via software command (e.g., 3V motor can be run with 24V supply). Commands can be issued from any serial terminal program (such as HyperTerminal) or from the EZStepper Windows application.

The EZQuad Servo will drive 4 motors at 2.5 Amps each with a setting of move current m=50 %. However, with careful selection of motors and/or improved cooling and/ or low move time duty cycle, it is possible to run motors at 5 Amps at m=100%. See Command Set for details.

Command Set for details.
The Commands are intuitive and simple. For example, the command A10000 will move the servo motor to Absolute position 10000. (This communications protocol is compatible with devices that use the Cavro DT or OEM protocol.)

The EZQuad Servo is also capable of standalone operation with no connection to a PC. It can be set to execute a preset string of commands upon power up (i.e., only power is required in this mode). The Commands include nested loops and execution halt pending a switch closure, which is useful in stand-alone applications.

The EZQuad Servo Motor Controller will typically work with any motor that is 3” or smaller (size23 or smaller). Starter Kits enable a first time user to make Servo Motors move intelligently in less than half an hour.

AllMotion Inc. develops and manufactures miniature high-performance stepper and servo drives for the medical, scientific, optical and general automation markets. Their mission is to create superior, ultra-compact motion control solutions that reduce costs and readily integrate into OEM instrumentation designs across a wide range of industries. R&D efforts are centered on core competencies of small form factor components that deliver precise positioning control and ease of use.

AllMotion provides off-the-shelf motion control devices and custom solutions based on their EZStepper and EZServo motor driver technology. Their servo motor controllers and brushless DC motor controllers feature quadrature encoder feedback, and are programmable to allow standalone operation. Based in San Jose, California, the company has proven leadership in miniature motion control, with a full line of intelligent driver/controllers.
