Operating principle - ServoRing HL rotary tables use segmented three phase synchronous brushless motor modules with high strength magnets on the rotors. The stator is made up of laminated stack and coil assembly with a large number of poles. Sinusoidal commutation of current control associated with the encoder feedback enables smooth torque generation with minimal torque ripple
Cooling - The motors can be cooled either by free air convection or water. Optional water cooling jacket can be installed in demanding applications when coolant is available.
Accuracy and repeatability - ServoRings HL are designed for high accuracy applications. They allow to position load much more precisely than geared or belt systems. Arc-sec accuracy and repeatability are achievable using high accuracy ring encoders and high stiffness ring bearings.
Motion smoothness - ServoRings HL have an inherent capability for extremely smooth motion achieved by closed loop controls with ring encoders. Direct drive systems are not subject to wear and backlash of mechanical systems. The smoothness of the operation and dynamic stability is maintained during lifetime of the machine
