Product Description:
The YSM323 is a brushless servo motor from Kollmorgen’s YSM Brushless Servo Motors series. It delivers controlled rotary motion for positioning and velocity loops in automated machinery such as pick-and-place arms, indexing tables, and packaging axes. When paired with a compatible drive, the unit converts electrical current into precise shaft torque to keep industrial processes synchronized. Its brushless design supports electronic commutation, reducing mechanical wear associated with motors that use brushes.
The motor supplies a continuous stall torque of 2.5 Nm, providing steady output when an axis must hold its position under load. During acceleration or brief shock loads, it can reach a peak torque of 7.1 Nm. Its 0.37 Nm/A torque constant indicates the relationship between phase current and generated torque, allowing the drive to calculate the current required for a commanded load. The motor has a back EMF constant of 40 V/kRPM, which supports voltage and commutation calculations across its operating range. Its maximum mechanical speed is 4500 rpm, making it suitable for moderate-speed direct-drive shafts. A phase inductance of 6.0 mH influences current rise time and the tuning of the drive’s current loop.
The mechanical interface uses a 90 mm bolt circle with 6.5 mm mounting holes, matching common IEC flange patterns for straightforward installation. The shaft end has an M5 × 0.8 tapped hole with a thread depth of 12 mm, simplifying the attachment of pulleys or precision couplings. The rotor has an inertia of 0.00006 kg·m², allowing the axis to respond rapidly to control commands while limiting overshoot. The motor has a total mass of 3.54 kg, making it suitable for cantilevered or slide-mounted installations that can support this load. An optical encoder provides 2000 lines of resolution, yielding 8,000 counts per revolution after quadrature decoding. Electrical heating is influenced by a phase resistance of 0.78 Ω. The bearings can tolerate an axial load of 20 kg and a radial load of 35 kg during operation.
