Product Description:
The 6SM 37M-6.000-09 synchronous servo motor is produced by Kollmorgen within the 6SM Synchronous Servo Motors series. It is a brushless AC machine engineered to deliver controlled rotary motion for positioning tables, pick-and-place heads, and other axis modules in industrial automation. By combining permanent-magnet excitation with feedback devices, the motor allows a drive to regulate velocity and torque precisely, supporting repeatable cycles and accurate trajectory tracking on assembly lines or packaging machinery.
Its electrical interface is compatible with 400/460 V systems, allowing a standard three-phase supply to feed the drive that powers the motor. During continuous duty, the windings draw a rated current of 1.5 A and convert the supplied electrical energy into a mechanical output of 0.5 kW. That power is produced at a synchronous operating speed of 6000 rpm, where the shaft delivers a rated torque of 0.8 Nm. This operating point keeps copper loss and winding temperature within the motor’s intended limits during continuous service. Because the rotor has six evenly spaced poles, the commutation frequency remains moderate, which eases current control and minimizes switching loss in the inverter. The brushless design also removes the mechanical wear and electrical arcing associated with carbon brushes.
When rapid acceleration or a load surge occurs, the inverter may supply a peak phase current of 6.5 A, enabling short bursts of torque above the rated level. The motor can hold position at zero speed with a standstill torque of 1 Nm, produced from a standstill current of 1.6 A. The winding has a thermal time constant of 15 minutes, allowing its temperature to rise gradually during intermittent overloads. Dynamic response is supported by a low rotor inertia of 0.7 kg·cm² and a magnetic torque constant of 0.62 Nm/A. Acceptable shaft loading is 90 N in the axial direction and 270 N in the radial direction, so applied thrust and belt tension must remain within these bearing limits. The low inertia supports fast changes in speed while reducing the torque needed to accelerate or decelerate the rotor.
