Product Description:
The TTB2-2952-3141-C is a direct-drive motor manufactured by Kollmorgen as part of the Inland Direct Drive Motors series. As a built-in rotary actuator, it mounts directly to the load without gear reduction, providing precise, backlash-free motion for indexing tables, servo presses, and other automated equipment. Within automated production lines, the unit eliminates the need for belt or gearbox couplings, improving positioning accuracy and reducing the maintenance associated with intermediate drivetrain components.
At its nominal operating point, the motor delivers 3 lb-ft of continuous torque while drawing a steady phase current of 8.04 A from a DC bus operating at 14.1 VDC. This operating point can be maintained continuously when adequate ambient cooling air is available. Mechanical output can reach 2000 rpm, and the direct coupling helps minimize the inertia and mechanical losses associated with an intermediate drivetrain. Despite the integrated electromagnetic brake and sizable stator stack, the assembly weighs 30.912 lb, allowing it to be supported by midsize machine frames without additional reinforcement. Its continuous-duty capability is suitable for repetitive applications such as feed rolls, capping stations, and wafer handlers.
Processes that require rapid indexing or emergency stops can use the motor’s short-term output capability. The windings accept up to 90 A, producing a momentary torque output of 25 lb-ft to overcome breakaway friction or accelerate heavy inertial loads. During these surges, the controller may raise the DC-link voltage to 115 VDC, which must be accommodated by the connected fuses and contactors. When power is removed, a spring-set brake secures the shaft with 6 lb-ft of static holding torque. The brake releases when supplied with 0.28 A at 90 V, allowing the shaft to rotate when the drive is ready for operation. This arrangement supports controlled acceleration and secures the connected load during a power interruption or planned stop.
