Sigma Mini Servo System SGMM/SGDF
Sigma Mini AC Servo Motors & Amplifiers are the
world s smallest in size, but BIG on performance! This makes them ideal for space confining applications, i.e. chip mounters, semiconductor manufacturing, and anywhere space is at a premium.
Two sizes are available, 10W and 20W, with rated torques of 4.5 and 9.02 oz-in, respectively. The 10W model is an amazing 1 x 1 x 2 !
Sigma stator design technology incorporates an innovative construction, which minimizes vibration and increases the overall heat transfer rate. This assures internal concentricity, permitting minimal air gap, reduced magnetic loss, and reduced motor volume required for a given continuous torque rating. This extremely compact design produces a high torque to inertia ratio thus maximizing torque, velocity and positioning performance.
A single, direct-coupled 2048ppr high resolution encoder (8192ppr after quadrature) provides the necessary commutation, velocity and position feedback without response delay caused by play/
distortion of coupling gears.
This is what Yaskawa’s Sigma Mini servo performance is all about - compact size, reliability, high speed, and precision.
Using the Sigma Mini SGMM servo motor with the new SGDF servo amplifier creates a matched package for optimum performance.
