Servo actuator eliminates unnecessary components

Wittenstein product story

Alpha Gear Drives' TPM+ servo actuator is composed of a high-precision gearhead, a high-pole motor and feedback all integrated into a single package.
TPM+ is the latest addition to the Wittenstein family of servo actuators.
It is composed of a high-precision gearhead, a high-pole motor and feedback all integrated into a single package.
Because the actuator concept eliminates any extra components, the size and mass have been reduced by 50% as compared to a standard motor and gearbox combination.
This small size and mass makes the torque density of the TPM+ the best in its class.
The high level of integration of the TPM+ has more benefits than just reduced size.
This new concept in actuator design eliminates the additional rotating parts that are used in a conventional solution, such as additional bearings, couplings, and larger shafts, decreasing the inertia of the actuator.
The the magnets are moved closer to the load, which improves stiffness and results in higher dynamics.
