Product Description:
The TBM-12995-A is a frameless brushless servo motor kit produced by Kollmorgen within the TBM Frameless Motors series. Supplied as separate rotor and stator components, it is intended for direct integration into robotic joints, gimbals, and other space-constrained axes where eliminating a housing improves power density. By allowing the machine builder to embed the electromagnetic core directly into the mechanical structure, this motor helps reduce overall envelope while providing precise torque control for industrial automation tasks.
The electromagnetic section is designed for a continuous phase current of 16.30 Adc, indicating the steady-state DC bus demand needed to maintain rated thermal conditions. Operation centers on a bus level of 100 VDC; drives using this voltage can deliver full performance without additional transformation. Under these conditions the motor can hold a shaft at 10.400 N·m indefinitely, giving designers a reliable figure for static load support or low-speed positioning. When commutated to its recommended electrical frequency, the rotor reaches a rated mechanical velocity of 1190 rpm, a speed suitable for medium-speed rotary actuators. Dynamic behavior during acceleration is influenced by a rotor inertia of 9.37E-04 kg·m², which strikes a balance between quick response and smooth control in servo loops.
Short-term overload requirements are addressed by a peak phase demand of 57 A, which the drive may supply for rapid acceleration or disturbance rejection without exceeding winding limits. During these bursts the motor can deliver up to 36.20 N·m, expanding the available torque reserve by more than three times the continuous rating. Mechanical integration is guided by an outside diameter of 128.88 mm, allowing the rotor-stator pair to nest inside compact gearheads or structural hubs, while a total mass of 4.050 kg minimizes added payload on moving axes.
