Technical Specifications
Frame size: NEMA 45. Rated speed: 3000rpm. Peak torque: 2.55Nm. Armature resistance: 3.2Ω. Moment of inertia: 0.32×10⁻⁴ kg·m². Operating temperature range: 0°C to +40°C. Protection rating: IP44.
Functional Features
Rare-earth permanent magnet design delivers high torque density. Low inertia rotor enables fast acceleration and deceleration. Brushed commutation provides simple drive interface. Compact NEMA 45 frame fits space-limited applications. Smooth low-cogging operation.
Application Scenarios
It applies to precision positioning systems, machine tool feed axes, packaging machinery, material handling systems, printing equipment and industrial motion control applications.
Material Composition
Housing: anodized aluminum alloy. Rotor: rare-earth permanent magnets. Shaft: hardened carbon steel. Bearings: sealed ball bearings. Commutator: copper with graphite brushes.
Structural Characteristics
It features round body NEMA 45 frame, keyed output shaft, rear brush compartment, side-mounted power terminals, and face mounting flange.
Working Principle
DC voltage applied to the armature creates current in the rotor windings. Interaction between rotor current and the permanent magnet field produces rotational torque. Brushes commutate current to the armature windings as the motor rotates, maintaining continuous torque output.
Installation Requirements
Mount via face mounting flange with specified bolt torque. Align shaft with load to avoid radial and axial misalignment. Use flexible coupling for transmission. Connect power with correct polarity. Ensure adequate heat dissipation.
