Material Composition
Housing: anodized aluminum. Rotor: permanent magnet. Stator: precision wound armature. Bearings: sealed ball bearings. Shaft: hardened steel.
Structural Characteristics
NEMA 45 round frame, keyed output shaft, terminal box, face mounting flange, and sealed rear cover.
Working Principle
The permanent magnet rotor rotates with the input shaft, inducing a DC voltage in the stator windings proportional to rotational speed. The output voltage provides a speed feedback signal to the drive controller for closed-loop speed regulation.
Installation Requirements
Mount via NEMA 45 flange. Couple to motor shaft with flexible coupling. Align shafts precisely. Connect output with correct polarity.
Usage Notes
Do not exceed maximum speed. Keep aligned to avoid bearing wear. Check output calibration periodically. Protect from moisture and contamination. Follow ESD procedures.
