Product Description:
The SBL2-0080-45/T0MVUS2 is a permanent-magnet synchronous servo motor manufactured by Kollmorgen as part of the DBL Synchronous Servomotors series. The unit converts controlled three-phase drive currents into proportional shaft torque and speed, allowing machine builders to position light payloads with repeatable accuracy. A 40 mm pilot diameter, 55 mm square flange, and 63 mm bolt circle give the motor a compact footprint, allowing direct mounting to small gearheads, ball screws, or timing-belt pulleys. Its compact mounting arrangement is suitable for semiconductor, packaging, and laboratory equipment where available installation space is limited.
At its continuous operating point, the motor reaches a rated speed of 4500 rpm when the applicable voltage, current, and thermal limits are satisfied. The motor provides 0.72 Nm of rated torque under continuous operating conditions, which helps determine suitable gear ratios and load inertia. To sustain this torque, the windings draw a rated current of 1.45 A, establishing the continuous current requirement for the connected servo drive. An electrical time constant of 0.88 ms indicates how quickly current can rise in the windings. This rapid electrical response supports controlled acceleration and responsive current regulation during changing load conditions.
When transient loads exceed the continuous operating range, the motor can produce a peak torque of 3.2 Nm. The connected drive can supply up to 6.8 A of peak current, enabling brief acceleration bursts and rapid responses to load disturbances. A phase-to-phase inductance of 13 mH limits current ripple and supports smooth electromagnetic force production. Heat accumulation is moderated by a thermal time constant of 22 min, allowing the motor temperature to rise gradually during intermittent overloads. The output uses a shaft with a diameter of 9 mm, providing a compact mechanical interface for compatible couplings and pulleys. Appropriate coupling alignment helps prevent unnecessary radial loading on the shaft and supports stable operation in precision motion systems.
