Product Description:

The TBMS-6013-B is a frameless brushless motor kit produced by Kollmorgen within the TBM Frameless Motors series. As a stator-rotor set intended for direct integration into custom mechanics, the unit delivers torque without a housing, allowing compact servo axes, gimbals, and articulated joints to eliminate transmission backlash. By embedding this core motor directly at the load, machine builders can raise dynamic accuracy while keeping overall mass low in precision automation platforms.

The electromagnetic core has a 59.06 mm outside diameter and a 27.94 mm axial length, dimensions that govern the space envelope inside a housing. A through bore of 28.7 mm permits cables, shafts, or optics to pass through the rotor centerline, supporting hollow-shaft designs. The 12 poles establish the magnetic geometry, and the 0.15 mH phase inductance together with the 0.355 Ω winding resistance set the electrical time constants. At 25 °C, the windings generate 3.66 Vrms per kRPM of back electromotive force, while a torque constant of 0.061 N·m per amp provides the conversion factor between phase current and output torque. Rotor inertia is only 0.0000141 kg·m², so acceleration response remains high for pick-and-place or stabilization tasks.

Under continuous load, the motor can supply 0.39 N·m with 6.78 Arms of phase current, and it can withstand momentary surges to a peak of 1.23 N·m for rapid indexing. When operated from a 24 VDC bus, the motor can reach 3540 RPM and deliver up to 103 W of mechanical power when paired with a compatible servo amplifier. Thermal performance depends on stall current and the copper loss associated with the stated winding resistance, so adequate conduction or forced convection must be provided by the surrounding structure. The motor is suitable for low-voltage mobile robots, collaborative arms, and compact medical devices.
