Product Description:

The SBL4-0260-2-24/T0BPV is a brushless AC servomotor produced by Kollmorgen within the DBL Synchronous Servomotors series. It converts electrical power from the DC bus of a paired servo drive into regulated rotary motion so that axes in assembly cells, pick-and-place stations, and light conveyor systems can be positioned accurately and repeatedly. By providing closed-loop speed and torque on demand, the unit serves as a compact actuator for tasks that require coordinated multi-axis movement in industrial automation.

A bolt circle diameter of 115 mm spaces the threaded holes that secure the housing, while the square mounting flange measures 105 mm across to fit standard IEC adapters. The pilot diameter of 95 mm centers the motor in the mating register, minimizing radial runout during repeated assembly. Output torque is delivered through a keyed shaft that is 19 mm in diameter, providing adequate torsional strength for couplings and pulleys sized for the motor class. Inside the rotor, laminated steel and permanent magnets produce a reflected inertia of 2.1 kg·cm². This moderate inertia allows servo loops to accelerate loads quickly without demanding excessive current from the drive.

Dynamic behavior is governed by an intermediate bus of 330/560 Vdc, at which the motor reaches a nominal speed of 3000 rpm. At this operating point, the motor can sustain a continuous torque of 2.3 N·m, ensuring stable motion for indexing tables or compact gantry axes. When stationary and fully energized, the winding generates a stall torque of 2.6 N·m. This additional torque allows the shaft to resist static loads before acceleration begins. The relationship between the available torque and reflected inertia determines attainable acceleration profiles and helps with the selection of a compatible servo amplifier.
