Product Description:

The SR03000-2G102A is a servo motor engineered by Kollmorgen for integration with the SP Servostar Servo Drives series. It converts electrical energy from the matched drive into controlled rotary motion for positioning machine axes in assembly cells, pick-and-place gantries, and other automated equipment. Resolver feedback allows the drive controller to monitor rotor position and maintain closed-loop control. The high-speed permanent-magnet rotor supports precise velocity and torque regulation throughout industrial automation cycles.

The motor delivers a continuous shaft torque of 0.84 N·m while drawing a phase current of 3 A RMS under steady thermal conditions. The motor can operate up to its mechanical speed limit of 7500 rpm. Its inverter operates from a 325 VDC bus, while the drive accepts a 230 VAC three-phase mains supply and produces a maximum line-to-line output of 250 V RMS. Four stator poles interact with the permanent-magnet rotor to produce a rated output power of 0.54 kW at the typical operating speed. The shaft-mounted resolver provides rotor position data so the controller can sustain vector commutation without an incremental encoder. An electromagnetic constant of 0.111 N·m/W indicates the relationship between torque production and copper losses.

Peak dynamic motion is supported by a torque crest of 1.91 N·m, attained with an instantaneous phase current of 6 A RMS. Heat leaves the stator through a thermal path rated at 1.30 °C/W and follows a 10-minute thermal time constant, allowing brief overloads before winding temperatures stabilize. The rotor has an inertia of 0.309 × 10⁻⁴ kg·m², which helps limit overshoot during rapid reversals. The complete motor has a mass of 2.5 kg, making it suitable for compact gantry heads while providing enough mass to damp minor vibrations. Smooth commutation supports consistent torque delivery across the motor’s usable speed range.
