RBE Frameless Series

RBE(H) Series Motors

The RBE series brushless motors provide a wide range of flexible motor solutions for frameless DDR (Direct Drive Rotary) motor applications.
. 10 frame sizes from 21.3mm to 239mm outside diameter
. Continuous Torque range from .01Nm to 38Nm
. Peak Torque range from .03Nm to 200Nm
. Speeds up to 35,000rpm
. Standard and custom windings to match speed/torque performance
These motors come in either housed (RBEH) or frameless (RBE) mechanical configurations. The Housed models come with stainless steel shafts and can include any combination of Hall sensors, encoder, or resolver as rotor position feedback devices.
The frameless configuration is supplied as two separate components (rotor and stator) and does not include a shaft, bearings, or endbells. Frameless motors are integrated directly with the load where the same bearings which support the load also support the motor. This configuration eliminates shaft, bearings, endbells, and couplings offering reduced volume, weight, complexity and also results in improved servo stiffness and quicker response. Frameless motors can include integral Hall sensors and additional position feedback devices such as encoders or resolvers would be added as separate components.
