Product Description:

The 6SM 45-S-3000-G synchronous servo motor is manufactured by Kollmorgen and belongs to the 6SM Synchronous Servo Motors series. It is a brushless rotary actuator that couples with Kollmorgen drives to provide tightly regulated motion for packaging stations, electronic assembly platforms, and other automation axes. By integrating a permanent-magnet rotor with high-density stator windings, the unit delivers smooth torque across the full control range while allowing the rapid acceleration profiles expected in pick-and-place and feed-roller systems. The motor is intended for flange mounting inside ventilated control cabinets or directly on machine frames.

Under continuous operating conditions, the shaft turns at 3000 rpm, producing 0.25 kW of mechanical output when the drive supplies a phase current of 1.4 A. At that load point, the electromagnetic structure generates 0.8 Nm of rated torque, while the 0.68 Nm/A torque constant indicates the proportional relationship between delivered torque and armature current. Magnetic energy is stored in the 54.0 mH winding inductance, a value that shapes current rise time and influences current-loop tuning. During standstill, the motor draws 1.3 A and can hold 0.85 Nm, allowing static positioning without an external brake. The rotor’s 1.5 kg·cm² inertia balances response speed with stability for mid-mass payloads.

The optional electromagnetic brake adds 1.06 kg·cm² of brake inertia and absorbs 16 W when energized by a 24 V DC supply. Once the brake is released, the motor can reach a peak current of 4.7 A to overcome load inertia during rapid indexing. If power is removed, the brake clamps the shaft with 6.5 Nm of holding torque to prevent drift on vertical axes. Thermal saturation is moderated by a time constant of 15 min, supporting cyclic tasks without excessive temperature fluctuations. Electrical losses across the copper windings are limited by a resistance of 25.4 Ω, keeping controller heat dissipation predictable.
