Product Description:
Kollmorgen produces the 6SM 37VL-6.000-G for its 6SM Synchronous Servo Motors series. This compact permanent-magnet unit is intended for precise velocity and position control in automated pick-and-place modules, packaging axes, and indexing tables where rapid acceleration and repeatability are required. Operating from a three-phase 400/460 V supply, the motor converts the drive’s sinusoidal output into rotary motion that can be coupled directly to timing belts, gearheads, or ball screws. When paired with a matching digital amplifier, the unit transforms commanded currents into proportional torque, providing accurate motion without mechanical transmission losses.
Under nominal conditions, the motor reaches a rated speed of 6000 rpm, producing 1.2 kW of mechanical output while delivering 2 Nm of continuous shaft torque. At this operating point, the stator draws 2.8 A of current, and the copper windings have 3.65 Ω of resistance and an inductance of 8 mH. These values affect servo loop bandwidth and heat generation during operation. For dynamic moves, the drive can command a peak current of 15.2 A for a limited period, giving the axis additional torque headroom without exceeding the insulation class. These electrical characteristics are compatible with common factory power systems, helping the motor maintain stable speed regulation under changing loads.
A standstill torque of 3 Nm, produced with 3.8 A, keeps the axis steady without relying on the mechanical brake. The electromagnetic design provides a torque constant of 0.79 Nm/A, enabling predictable force output per ampere, and a voltage constant of 48 V/1000 rpm that supports accurate commutation. For mechanical integration, the shaft tolerates 270 N of radial load and 90 N of axial load, allowing direct coupling to pulleys or pinions. The housing has an IP65 protection rating, keeping dust and low-pressure water jets away from internal components. The brake operates from a 24 VDC supply, keeping its holding function independent of the main power bus.
