Product Description:

The HSM630 is a brushless servo motor produced by Kollmorgen for the HSM Brushless Servo Motors series. It provides controlled shaft rotation for positioning and speed regulation tasks in automated machinery, allowing drives to synchronize motion axes without relying solely on mechanical transmission components. Typical installations include gantry loaders, packaging indexers, and material-forming stations where repeatable torque and accurate movement are required. Its brushless design supports responsive operation during repetitive acceleration, deceleration, and constant-speed cycles.

At the electrical level, the motor generates a back electromotive force of 85 V/kRPM, indicating the voltage feedback that the drive must accommodate as speed rises. Steady load capability is represented by a continuous torque of 33.9 Nm, while short bursts of up to 79.1 Nm supply additional acceleration for indexing or cutter engagement. These torque values are reached with a torque constant of 0.77 Nm/A, allowing the associated amplifier to estimate mechanical output from phase current. Dynamic response is influenced by a rotor inertia of 0.00339 kg·m²; this moderate inertia supports fast reversals while providing enough stored energy to reduce minor speed ripple during constant-velocity movement.

The phase windings have an inductance of 1.2 mH and a resistance of 0.12 Ω, which affect current rise time and heat generation under high-duty operating cycles. The motor housing weighs 34.8 kg, providing thermal mass that slows temperature changes during continuous operation. A bolt circle diameter of 200 mm with 13.5 mm mounting holes supports secure attachment to the machine structure. The shaft includes a 20 mm deep M8 × 1.25 mm thread, and the motor has an overall length of 429 mm for integration with gearboxes or belt pulleys. When the factory-supplied holding brake is fitted, the assembly length increases to 482 mm, so the installation must provide sufficient axial clearance.
