Product Description:

The 6SM 45-M3000-A is a frame-size 45 synchronous servo motor produced by Kollmorgen within the 6SM Synchronous Servo Motors series. The unit is built for closed-loop industrial axes that need repeatable positioning, speed tracking, and moderate continuous power. By converting drive current into controlled rotary motion, the motor couples directly to gearboxes, ball screws, or belt transmissions and supplies the mechanical work required in automated assembly, packaging, or inspection stations.

During continuous operation, the motor draws a rated phase current of 1.3 A from the servo amplifier. Under those electrical conditions, it provides 0.5 kW of mechanical power while producing 1.6 Nm of torque at a shaft speed of 3000 rpm. The housing has an IP65 protection rating, sealing the stator against dust and water jets so the motor can be mounted outside control cabinets. The bearing design supports a radial shaft load of 370 N and an axial load limit of 120 N, allowing direct belt tension or pinion forces without premature wear. A winding inductance of 99.0 mH and resistance of 34.0 Ω establish the electrical time constant that the drive must accommodate for stable current control.

The electromagnetic constants further characterize dynamic behavior. A torque constant of 1.36 Nm/A links phase current to produced torque, while a standstill torque capability of 1.7 Nm lets the motor hold its position when energized. The rotor inertia is 2.1 kg·cm², providing low stored energy for quick acceleration while retaining sufficient damping for smooth speed regulation. With a mass of 5.5 kg, the assembly adds a manageable load to compact gantries. The back-EMF coefficient is 116 V per 1000 rpm, so the drive must supply proportionally more voltage as speed rises. A 20-minute thermal time constant governs temperature rise during intermittent duty, allowing short overloads before the winding temperature reaches its limit.
