Universal Interface
l
Because of the extreme versatility of the Driver Unit design, a wide variety of interface methods
are possible. The Megathrust Motor System can be interfaced to virtually any control system. It
is very easy to control the Megathrust Motor System with a CNC, a servo motor controller, a
robot controller, or an positioning controller. You can operate the Megathrust Motor System
with a stepper motor controller or with a personal computer or dumb terminal. Versatile position
control can even be implemented with a single switch!
High Repeatability
l
With zero backlash, direct drive and a high resolution resolver, the Megathrust Motor System
offers repeatability as high as 1 micron, or approximately 0.000039 inch. With no mechanical
contact or moving parts other than the Linear Guides, this repeatability will never degrade.
Easy to Maintain
l
With all adjustments, indicators, and test points accessible by the front panel, service or
maintenance is easy. LED (light-emitting diode) and logic diagnostic outputs identify the nature
of any error condition quickly and accurately.
l
Together, the Motor and the Driver Unit provide the ultimate in simplicity for precise and
reliable motion control.
Single Component Servo System
l
A conventional brushless servo system requires at least several separate components which must
be selected and packaged together, often at great expense. Furthermore, many of these
components introduce problems of their own to degrade the entire system’s performance. Ball
Screw type actuators, for example, introduce mechanical irregularities such as windup, backlash,
and mechanical inaccuracy. The same functions can be accomplished with just two components
using the Megathrust Motor System; all of the circuits needed to implement a position or
velocity control servo loop (digital motion controller, servo compensation, brushless
commutation logic, power amplifier) are included in the Driver Unit, and all of the mechanical
components that were required (motor, couplings, ball screw, linear guides and encoder) are
either replaced or made unnecessary by the Motor.
Long Stroke and Small Cross Section Area
l
Different from the ball screw system, the cross section area of the Megathrust Motor does not
depend on the stroke. By jointing unit rack bases, up to 30 meters rack base length can be
represented while maintaining the same cross section area. In addition, because the rack base
length does not affect to the repeatability, precise positioning is possible over the full stroke.
Multi Slider System
l
One of the other unique merit of the Megathrust Motor is that several sliders can be mounted on
the same rack base and can be controlled independent of the others. This also will contribute to
design versatile system simple.
