This latest solution from WITTENSTEIN's actuation family offers superior power density in an exceptionally compact package.
The TPM+ power is available in a single-stage version - well suited for rack-and-pinion or other high speed applications - or as a two-stage actuator for rotary drive tasks. Various reduction ratios are offered to facilitate an actuator design characterized by optimal energy efficiency and dynamics. Helical toothing in the gearhead allows for smoother running at the output and the influence of meshing frequencies is minimized with the overall noise level at 6 dB lower than alternative technologies.
The permanent magnet synchronous motors developed by WITTENSTEIN offer remarkable power density mainly due to the high pole count and the optimum copper fill factor in the slots. At the same time, the high quality of the laminations in the stacks helps optimize the power balance by limiting losses due to eddy currents. As for the feedback systems, WITTENSTEIN relies on the robust technology of rugged resolvers and the precision of optical encoders using the EnDat and Hiperface protocols. A backlash-free permanent magnet brake is available as an option.
