PATENTED FEATURE FOR STEPPER MOTORS<br />
sensorless stall detection<br />
sensorless load detection
STALL DETECTION: Applications<br />
FOR OPTIMIZED AND SYMPLIFIED SYSTEMS<br />
homing without end- or reference switches<br />

OPERATING CONDITIONS: Requirements<br />
TO USE THE STALL AND LOAD DETECTION<br />
minimum velocity <strong>stallGuard</strong> needs BACK EMF<br />
constant velocity <strong>stallGuard</strong> level depends on velocity<br />
<strong>is</strong> not an encoder replacement!<br />
for evaluation <strong>and</strong> optimization of system conditions<br />

MARKETS: <strong>stallGuard</strong><br />
STEPPER MOTOR SOLUTIONS<br />
The <strong>stallGuard</strong> feature gives advantage in many markets like:<br />
lab au<strong>to</strong>mation / biotec / medical equipment<br />
banking / card reader / POS<br />
semiconduc<strong>to</strong>r equipment<br />
high end office au<strong>to</strong>mation / printing<br />
robotics<br />
blood analyzer cash recycler / A<strong>TM</strong> die bonder<br />
skinning / strip equipment
CONCLUSION: why <strong>stallGuard</strong><br />
BENEFITS<br />
reduce cost - save money<br />
increase prec<strong>is</strong>ion<br />
ra<strong>is</strong>e reliability<br />
simplify solutions<br />
be more competitive with
