Product Description:

The RBEH-01210-E14 is a frameless rotary motor element manufactured by Kollmorgen within the RBE Rotary Motors series. Supplied as a rotor-stator kit rather than a fully housed assembly, the unit is intended for direct embedding into lightweight spindles, optical platforms, and miniature actuators. In automation systems, it converts three-phase drive current into continuous rotary motion, allowing high-speed positioning without the additional mass of gear trains or couplings.

During operation, the motor can sustain a 0.115 N-m continuous stall torque while remaining thermally stable. For transient events such as rapid indexing, it supplies up to 0.342 N-m of peak torque, providing a three-to-one overload margin. The rotor can safely spin to an upper mechanical limit of 18000 rpm. The electromagnetic design places the rated output of 106 W at a controlled operating point of 13800 rpm, where copper loss and iron loss are balanced. Static friction is limited to 0.0120 N-m, allowing smooth startup with low drive current, and power conductors leave the stator as 20 AWG leads that are pre-trimmed to 152 mm for compact terminations.

The dynamic response is aided by a housed inertia of 5.37 × 10⁻⁶ kg·m², so servo loops can accelerate and decelerate the load with minimal phase lag. An 8-pole rotor produces high torque density while keeping electrical frequency manageable, and the refined magnet layout limits cogging torque to 0.0029 N-m for smooth constant-speed moves. Thermal energy passes through the frame along a path rated at 4.25 °C/W, allowing the relatively light 0.320 kg assembly to run at its limits without overheating. Hall effect devices for commutation use five 26 AWG sensor leads that match the 152 mm length of the power conductors, minimizing wiring variation inside the host machine.
