TPM+ dynamic / TPM+ power
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.

alpha Planetary Gearheads
alpha introduced the world’s first high speed inline planetary gear reducer and continues to create
groundbreaking inline solutions. From the compact precision of the TP+ to the economical performance
of the LP+ and the classic solution of the SP+, alpha has an inline planetary solution for your needs
- be it off-the-shelf or custom engineered. The newest addition to the inline series is the
alphira™ - the basic precision. Fast, flexible and efficient. Packaged in a lightweight case,
alphira™ is precise, power-dense and maintenance-free.

Ternary Intelligent Linear Actuator
Ternary™ is an all-in-one linear and rotary actuator system that merges mechanics with intelligence,
integrating several separate components: electronics, precision mechanics, feedback, control and
software. Ternary™ is ideal in all situations where a pneumatic cylinder isn’t enough and a servo
is too expensive or too complicated. WITTENSTEIN’s linear and rotary system allows multiple positions
to be controlled with utmost precision and control, while the completely integrated package keeps
wiring and setup time, and thus costs, to a minimum. Compactness, strength, intelligence and precision
are the hallmarks of the linear actuator. Ternary actuators can be used on a Profibus, CanOpen or
DeviceNet Fieldbus, controlled via discrete IO or Fieldbus interface.
