Kollmorgen RBE-03011-A00 Brushless Frameless Servo Motor

Kollmorgen RBE-03011-A00 Brushless Frameless Servo Motor

Introduction

The Kollmorgen RBE-03011-A00 is a high-performance, frameless brushless rotary servo motor engineered for Direct Drive Rotary (DDR) applications.

Part of Kollmorgen’s renowned RBE series, this rotor-stator kit is designed to be integrated directly into a machine's mechanical structure, completely eliminating the need for traditional components like housings, shafts, bearings, or couplings.

By leveraging high-energy rare-earth magnets (Neodymium-Iron-Boron) and a 12-pole design, the RBE-03011-A00 provides extreme torque density, high dynamic responsiveness, and zero backlash in a highly compact form factor.

Product Advantages and Features

Zero-Backlash Direct Drive: Eliminates mechanical transmission elements (gearboxes, belts, pulleys), completely removing backlash and compliance errors while drastically optimizing servo stiffness.

High Torque-to-Volume Ratio: The 12-pole configuration and rare-earth magnets ensure maximal electromagnetic torque output from an incredibly lightweight 2.43 kg footprint.

Minimal Speed Ripple: Designed with a low cogging profile (0.140 N·m peak-to-peak) to guarantee smooth low-speed rotation and highly precise velocity control.

Thermally Efficient Frameless Design: Inserting the stator directly into the machine frame allows the adjacent metal structure to act as a massive heat sink, greatly increasing continuous power efficiency.

Sleek Machine Profile: Enables a large through-bore structure through the center of the rotor, allowing wiring, piping, or laser lines to pass directly through the axis of motion.

Unique Product Description

Kollmorgen RBE-03011-A00: The Frameless Powerhouse for Space-Constrained Motion

The RBE-03011-A00 represents the pinnacle of embedded motion design.

Delivered purely as an independent rotor and stator pair, it transforms your machine's existing structural bearings into the motor's own support system.

With an impressive peak torque of 32.2 N·m and a rated power of 832 W, it provides hard-hitting mechanical work directly at the load face.

If your engineering envelope demands minimal weight, maximum structural rigidity, and zero-maintenance operation without the bulky footprint of traditional housed servo motors, this kit delivers flawless closed-loop current execution.

Application Cases

The unique frameless geometry and high dynamic performance of the RBE-03011-A00 make it perfect for demanding industries:

Robotics & Gimbals: Multi-axis robotic arm joints and high-precision pan-tilt camera gimbals where weight distribution and zero backlash are critical.

Semiconductor Processing: Wafer handling, indexing tables, and pick-and-place equipment requiring cleanroom compatibility and smooth velocity profiles.

Aerospace & Defense: Optronic mast drives, unmanned system actuators, and targeting mechanisms capable of handling intense thermal fluctuations.

Medical Equipment: High-end imaging systems (CT, MRI scans) and surgical robotics requiring precise positioning and low electrical noise.

Installation and Maintenance

Installation Guidelines

Alignment Accuracy: Because this is a frameless motor kit, concentricity between the rotor and stator must be carefully controlled during assembly according to Kollmorgen's air gap tolerances.

Axial Placement: Ensure the rotor is properly centered axially within the stator core to maximize magnetic flux utilization and avoid unwanted axial magnetic forces.

Handling: Use caution when handling the rotor; the high-energy permanent magnets will forcefully attract any nearby ferrous tools or particles.

Maintenance Requirements

Zero Maintenance Mechanics: Because there are no internal motor bearings, brushes, or seals, the motor itself requires zero mechanical maintenance over its operational life.

Environmental Protection: The RBE-03011-A00 is open-frame and lacks environmental sealing. It must be housed in an enclosure that protects it from dust, metallic shavings, and liquid infiltration.
