Performance Parameters
Rated torque: 0.71Nm @ 2500rpm. Speed regulation: ±5% across load range. Maximum speed: 3200rpm. Operating temperature range: 0°C to +40°C.
Material Composition
Housing: anodized aluminum. Magnets: ceramic ferrite. Shaft: hardened steel. Bearings: shielded ball bearings. Brushes: carbon-graphite.
Structural Characteristics
Round body NEMA 45 frame, keyed shaft, rear brush access plate, terminal box, and face mounting flange.
Working Principle
DC current applied to the armature interacts with the permanent magnet field to produce torque. Brushes transfer current to the rotating armature via the commutator. Speed varies proportionally with applied voltage.
Installation Requirements
Mount via standard NEMA 45 flange. Align shaft with load. Use flexible coupling. Observe correct polarity. Allow adequate ventilation.
