SERVO DUTY

Harowe™ brandSize 21 HaroMax

Heavy Duty Brushless Resolvers
Key Features• Frameless size 21 Servo Mounting• Anodized Aluminum Housing with Low Mass
• Machine Wound Stator for High Accuracy
Provides absolute position and/or velocity feedback
for brushless motors, robots, servos, precisionrotary platforms and many other applications
where high temperature, shock and vibration are a
problem for less robust feedback products.
Because of its simple transformer design andlack of any on-board electronics, the resolver is asensible choice for many aerospace, military, steeland paper mills and radioactive applications wherereliable performance is required.
