Product Description:
The 6SM 57M-3000-G is a synchronous servo motor from Kollmorgen and is part of the 6SM Synchronous Servo Motors series. Designed for closed-loop positioning and velocity control in automated machinery, the unit converts drive current into precise shaft torque so actuators, conveyors, or pick-and-place heads can follow programmed motion profiles. Its frame connects to compatible Kollmorgen drives and feedback devices, allowing integration into packaging lines, electronic assembly tables, and general industrial axes that require repeatable cycle times.
The motor delivers a continuous output of 1.9 kW at its nominal shaft speed of 3000 rpm. At that operating point, it produces 6 Nm of electromagnetic torque while drawing 4 A from the drive amplifier. With a torque constant of 1.85 Nm/A, each ampere of incremental current increases torque at a predictable rate, simplifying current-loop tuning. The three-phase winding has a resistance of 3.9 Ω and an inductance of 24 mH, which affect copper losses and current ripple during pulse-width modulation. A voltage constant of 112 V per 1000 rpm characterizes the back electromotive force seen by the inverter. The embedded thermal contact opens near 145 ± 5 °C to protect the insulation from excessive heat. The standstill current requirement is 4.3 A for static holding applications.
During acceleration or rapid disturbance rejection, the drive may supply a peak current of 17 A, allowing the rotor to overcome inertia and external loads. In stationary holding mode, the motor can sustain 8 Nm without shaft movement, while the front bearing supports a rated radial load of 650 N. The laminated rotor has an inertia of 4.5 kg·cm², providing a balance between responsiveness and mechanical damping. A spring-applied brake energized at 24 VDC (+6/-10%) secures the axis when power is removed. The brake releases when the specified control voltage is applied, allowing normal shaft rotation during powered operation. Thermal saturation is moderated by a 20-minute thermal time constant, which governs how quickly the frame temperature responds to heat generated in the windings.
