Product Description:

The RBEH-01210-A14 rotary motor is manufactured by Kollmorgen as part of the RBE Rotary Motors series. It serves as an electric torque source in industrial automation, where it drives axes that require high speed and moderate torque with precise current control. With a 57.658 mm body diameter and a 9.520 mm shaft, it fits compact machine frames where installation space is limited. Its compact form also suits light rotary axes and other motion systems that benefit from fast response.

At a rated speed of 13800 rpm, the motor sustains mechanical output up to 106 W. To maintain that operating point, it draws a continuous current of 5.41 A through a phase resistance of 0.698 Ω. Continuous stall torque is 0.115 N·m, which allows steady holding capability when motion is stopped. The torque constant is 0.0236 N·m/A, so each ampere contributes proportionally to shaft torque, and the back-EMF constant is 2.47 V/KRPM, indicating the voltage required as speed rises. A motor constant of 0.028 N·m/√W relates thermal loading to electromechanical output, and the 48.26 mm mounting bolt circle supports installation on standard servo flanges.

In dynamic moves, the motor can produce a peak torque of 0.342 N·m for short intervals, and the rotor can accelerate toward a mechanical ceiling of 18000 rpm before commutation limits are reached. Electrical response is influenced by the winding inductance of 0.280 mH, which works with the low resistance to affect current rise time. Thermal behavior is characterized by a conduction path of 4.25 °C/W, which indicates how quickly winding heat reaches the frame. The eight-pole geometry helps keep torque ripple low at high speed, and the shaft transmits motion directly to properly sized couplings. These operating relationships guide current, duty-cycle, and cooling choices so the motor remains within its thermal limit during use.
