-
Technical Specifications:
-
Torque Range: Approx. 69 to 143 oz-in (0.49 to 1.02 Nm) continuous depending on winding
-
Design: Flat disc armature, no iron core
-
Commutation: Typically brush or brushless (check specific S1 variant)
-
Feedback Options: Tachometer, encoder, resolver (optional)
-
-
Functional Features: Zero cogging torque, up to 10x faster acceleration than iron-core motors, compact pancake form factor, silent operation.
-
Material & Structure: Copper disc armature, permanent magnets on end plates (axial field), lightweight non-ferrous construction.
-
Working Principle: Current flows radially through copper disc interacting with axial magnetic field; torque generated perpendicular to field and current (left-hand rule).
-
Applications: High-speed gimbals, optical scanning, medical lab automation, semiconductor wafer handling.
-
Installation: Unique form factor requires custom mounting; sensitive to axial thrust loads.
-
Notes: Obsolete/discontinued series; replacements may require retrofit considerations.
