Product Description:
The 6SM 27M-4.000-G is a synchronous servo motor manufactured by Kollmorgen in the 6SM Synchronous Servo Motors series. It is intended for precision positioning and velocity control in industrial automation, translating drive commands into accurate shaft rotation for packaging stations, small gantries, and indexing tables. The motor includes a 24 VDC electromagnetic brake that secures the load whenever the drive is disabled, and its compact rotor construction with 0.08 kg·cm² of inertia allows quick speed changes without significant overshoot.
The continuous output of the unit is rated at 0.13 kW, delivering mechanical work at a nominal shaft speed of 4000 rpm. At this point, it produces a steady 0.30 Nm while drawing 0.75 A from the drive. During rapid acceleration, the current may rise to 3.5 A, supplying extra torque for short intervals. A torque constant of 0.41 Nm/A links every ampere of phase current to usable torque, simplifying current-loop tuning. Standstill values are 0.80 A and 0.32 Nm, respectively, confirming that the electromagnetic design maintains torque even at zero speed for holding or indexing tasks. The low motor inertia limits the load seen by the drive amplifier, reducing control effort during high-frequency reversals.
The holding brake supplies 1 Nm of static torque and is powered by a coil that consumes 8 W. It adds only 0.07 kg·cm² of inertia, so dynamic response remains largely unchanged. Thermal equilibrium is reached after 10 min, giving a predictable window for temperature monitoring in intermittent-duty applications. The stator winding presents an inductance of 21 mH and a resistance of 31 Ω. These parameters affect the current rise time and Joule losses inside the motor.
