Excellent accuracy from air bearing stages
Aerotech has launched a new range of air-bearing stages called the ABL2000, available in travel lengths up to 1.2m and speeds from 0.1mm/second to 3m/second.
Ultra-high acceleration from linear motor stage
With the Aerotech ALS130 Series, bi-directional repeatability of a staggering 0.1 microns is paired with a maximum speed of 300mm/sec and a breathtaking no-load acceleration of 1G!
The motors are ideal replacements for AC or DC, brushed and brushless motors in metrology, machine tool or scanning applications and elsewhere where superior velocity smoothness and control are required.
Better stability and easier tuning are a result of the motor's ability to match more closely the inertia of mechanical systems.
It does this thanks to the slotless stator which, by the nature of its construction, inherently eliminates cogging and results in the smooth velocity control.
A variety of encoder options can be fitted to the motor to suit specific applications.
In addition to the standard RS422 line driver output, an optional sine wave encoder can be used to provide ultra-high resolution.
Indeed, Aerotech's own MX multiplier box accepts sine wave encoder and RS422 line driver outputs to enable resolutions over 4 million counts per motor revolution.
Two sizes of BMS motor are immediately available in 175W and 217W with rated speeds of 4000rev/min and 3000rev/min and constant torque ratings of 0.16Nm and 0.32Nm respectively.
Maximum acceleration is 85,000rad/sec2 and 74,000rad/sec2.
Like all brushless motors, the BMS range is more reliable than DC brushed equivalents. Request a free brochure from Aerotech ...
