This motor uses an optical multiturn absolute Hiperface encoder that preserves position over power cycles and reports both angle and turn count for repeatable homing-free control. Hiperface is a serial absolute interface widely used in servo systems.

The convection (no forced air) method permits continuous torque rating around 14 Nm at 100 K. Keeping fins clean and ambient within spec sustains the published rating and prevents thermal limiting.

An electrically-released holding brake provides static holding torque to secure Z-axes or web tension at rest for reducing reliance on mechanical locks. It is not intended for dynamic stopping; use drive-based braking for motion.

Its B-side orientation routes power away from encoder cabling for improving EMC separation and easing dress-pack layouts on gantries or cartesian robots. It minimizes coupling into feedback pairs and reduces commissioning noise issues.

The cylindrical (non-keyed) shaft favors zero-backlash clamping hubs or shrink-disc couplings for high precision. Its proper hub fit and alignment preserve bearing life and maintain low torsional wind-up under peak 44 Nm events.
