Product Description:

The RBE-03010-E00 is a frameless rotary motor kit manufactured by Kollmorgen within the RBE Rotary Motors series. Designed for direct embedding into gimbals, semiconductor stages, and other position-critical mechanisms, this motor supplies electromagnetic torque without the mass of a full housing. When mounted inside the host machine, its stator and rotor operate as the prime mover, translating drive current into precise rotary motion for tightly controlled industrial automation cycles. Because the kit is built for direct integration, it can reduce the need for couplings or other transmission parts that add backlash and inertia.

At its rated operating point, the motor delivers 3.00 N-m of continuous torque and reaches 3000 rpm, supporting steady servo operation in compact rotary axes. The electromagnetic structure uses a 12-pole rotor, which helps reduce torque ripple; residual cogging torque is limited to 0.0706 N-m and static friction to 0.127 N-m, helping the axis start smoothly under low-speed control. The junction-to-case thermal resistance is 1.55 °C/W, so forced-air or conduction cooling can keep winding temperature within normal limits. The motor can also reach speeds up to 8300 rpm, and viscous damping of 6.86 × 10⁻⁵ N-m/rpm keeps drag low during rapid acceleration.

For intermittent events such as indexing or shock loading, the rotor can generate a peak torque of 20.6 N-m for short durations, allowing rapid moves without stalling. Electrical-to-mechanical conversion efficiency is characterized by a motor constant of 0.418 N-m/√W, while the torque coefficient is 8.49 N-m per ampere, which makes the current-to-torque relationship easy to interpret in closed-loop control. When driven near its power ceiling, the unit can output 644 W while still benefiting from the same winding design that helps limit internal losses. This behavior is useful in axes that alternate between dwell periods and brief acceleration phases.
