Product Description:
The 6SM 47L-3000 is manufactured by Kollmorgen within the 6SM Synchronous Servo Motors series. The motor converts three-phase drive commands into rotary motion for positioning gantries, feeders, and rotary actuators in automated equipment. It supplies repeatable torque and speed under servo control while maintaining a compact frame for enclosure or direct machine mounting. Its synchronous design supports controlled acceleration, steady rotation, and accurate positioning when paired with a compatible servo drive.
The stator is optimized for operation with a 400/460 V supply and delivers a rated mechanical output of 0.69 kW at the shaft. Under this load, the motor draws a rated phase current of 2 A while producing 2.2 Nm of torque at a nominal speed of 3000 rpm. For rapid acceleration, the current can rise momentarily to 9 A without demagnetizing the rotor. The winding resistance is 11 Ω, which helps keep copper losses moderate during operation. A phase inductance of 25 mH filters switching harmonics from the inverter and affects the response of the current control loop.
At standstill, the windings can draw 2.3 A to generate 3 Nm of torque, helping powered vertical axes maintain their position when no brake is installed. The rotor inertia is 1.6 kg·cm², enabling quick directional changes without requiring excessive servo gain. The shaft can withstand an axial thrust of up to 90 N and a radial force of up to 270 N without damaging the bearings. A thermal time constant of 15 minutes provides a useful interval for temporary overload operation before the motor reaches thermal equilibrium. The electromagnetic design provides a torque constant of 1.33 Nm/A, which relates phase current to the torque generated by the motor. The generated back EMF is 81 V/1000 rpm, an important value for selecting a suitable bus voltage and managing regenerative operation.
