Product Description:
The 6SM 37VL-6000 is a compact synchronous servo motor manufactured by Kollmorgen within the 6SM Synchronous Servo Motors series. Designed for closed-loop motion systems, it converts electrical input from a compatible drive into controlled rotary movement for positioning axes, pick-and-place heads, and lightweight gantry drives. In industrial automation, the unit provides rapid velocity transitions and precise positional repeatability while occupying minimal space within the machine.
At its continuous operating point, the motor produces 1.2 kW of mechanical power while running at 6000 rpm; this combination indicates the sustainable operating limit without excessive heat buildup. The shaft delivers a nominal torque of 2 Nm when the stator windings draw a continuous phase current of 2.8 A. During startups and brief overloads, the amplifier may supply up to 15.2 A, enabling quick acceleration before thermal monitoring restricts the duty cycle. The bearings tolerate an axial thrust of 90 N and a radial force of 270 N, supporting moderate belt or pinion side loads. The winding has an inductance of 8 mH, which affects the current rise time. A thermal time constant of 15 minutes indicates how quickly the motor approaches a steady operating temperature under sustained loading.
Static holding capability is provided by a standstill torque of 3 Nm, allowing an idle axis to resist external disturbances without a mechanical brake. Responsive servo behavior is aided by a rotor inertia of 1.6 kg·cm², which supports high acceleration and short settling times. The motor has a torque constant of 0.79 Nm/A, indicating the amount of torque produced for each ampere of phase current. Drive losses remain manageable because the phase resistance is 3.65 Ω. The moderate bearing load capacities support direct couplings, compact gear stages, and appropriately tensioned belt mechanisms. The electrical values help a compatible servo amplifier regulate current accurately during acceleration, constant-speed operation, and controlled deceleration.
