Product Description:
The model number PMB31D-00114-00 is produced by a renowned industrial brand Pacific Scientific. This brushless servomotor connects via flying leads with AMP connectors and allows rapid and secure electrical mating. Classified as NEMA Size 34, the device uses standard mounting patterns to streamline retrofit into existing systems. It offers an encoder resolution at 2048 ppr supplies with high fidelity position feedback that sharpens motion precision.
A digital encoder with commutation handles both feedback and rotor alignment which improves drive stability. A stack length multiple build allows modular adjustments that simplifies customization for torque needs. The motor’s nominal stall current of 5.4 ARMS at 240 VAC defines base power draw which helps in drive sizing. Key specifications include continuous stall torque of 2.11 Nm (18.7 lb‑in) delivers steady rotational force which sustains load-driven motion. Also, the peak torque of 6.26 Nm (55.4 lb‑in) accommodates transient acceleration demands to improve dynamic responsiveness. Inertia is rated at 0.137 kg·m²×10⁻³ (1.21 lb‑in·s²×10⁻³) and minimizes resistance to rotation which reduces energy consumption during startups.
The PMB31D-00114-00 with maximum static friction of 0.09 Nm (0.80 lb‑in) sets baseline resistance, allowing precise holding when stationary. A viscous damping coefficient of 0.0124 Nm/kRPM (0.110 lb‑in/kRPM) regulates rotational decay which enhances position stability. Thermal resistance of 1.08°C/W enables predictable heat dissipation which supports thermal management. Moreover, motor-only weight of 2.5 kg (5.5 lbs) balances compact mass with structural robustness for installation ease. Device’s torque constant of 0.79 Nm/ARMS (7.03 lb‑in/ARMS) links current to torque potential which aids in drive tuning. Voltage constant of 0.49 VRMS/rad/s (51.3 VRMS/kRPM) defines EMF generation per speed unit which enhances velocity control. Additionally, the peak current of 8.0 ARMS supports short-term power bursts which aid rapid acceleration. Resistance (line-to-line) of 7.6 Ω sets electrical path load which affects heating and control loops.
