Reliable precision in the highest purity

The HHA Hygienic Hollow Shaft Servo Actuator combines the latest motor technology, a high performance Harmonic Drive® CSG Gear Component Set and a high capacity tilt resistant output bearing. The Hygienic Design Actuator combines the expected reliability and highest performance of Harmonic Drive® Actuators in a specially designed stainless steel housing for compliance with hygiene standards. It scores not only with a clean simple design to assist with washdown, but also with selected surface finish and a large hollow shaft to pass cables and supply lines. The HHA Hygienic Design Actuator is manufactured with a European supply
chain at the Limburg production site.

• Food grade grease
• High performance motor technology at the Limburg production site

High dynamics in a compact assembly

The BHK Series Frameless motors are characterised by a high overload capacity combined with low weight and low moment of inertia.

This means that the BHK Series offers maximum dynamics for fast positioning tasks - with the additional option of realising a large hollow shaft.

Flexibility in machine design

The BHK Series Frameless motors consist of a moulded stator and a ring magnet. This allows the frameless motors to be used to customise the complete drive solution. The motor or machine manufacturer can integrate the frameless motors according to their specific requirements, realise their own bearings and design an encoder system according to their wishes. The short overall length of the frameless motors enables a compact drive design. The large hollow shaft in the ring magnet can also be used for a hollow shaft of the complete drive solution so that, for example, supply lines, compressed air hoses or similar can be routed through the rotary axes of the machine.

Thanks to a high number of pole pairs and a high copper fill factor, the BHK Series Frameless motors achieve a high torque density and are therefore ideal for dynamic positioning applications with the necessary overload reserves.

Due to their design principle, the BHK Frameless motors have low cogging, which in turn results in very good synchronisation characteristics with low speed ripple.

The integrated linear PT1000 temperature sensor can be used not only for safety shutdown in the event of overtemperature, but also for analysing the operating temperature, thus providing a basis for condition monitoring.

Economical design

The economical design and optimised manufacturing technology offer a cost effective and precise drive system with high overload capacity - especially for large quantities.

Sensors enable the precise measurement of the values needed to determine the state of a drive system. Harmonic Drive® Torque Sensors determine the load situation of an actuator and help to prevent overloads or enable safe human machine interaction or force feedback functions.

Triangle Technology is based on a revolutionary further development of the proven Harmonic Drive® operating principle.

The rounded triangular shape of the Wave Generator creates three tooth engagement areas between the Flexspline, which has external teeth, and the Circular Spline, which has internal teeth.

The rotation of the Wave Generator causes a permanent circumferential tooth engagement between Flexspline and Circular Spline. Since the Flexspline has three teeth fewer than the Circular Spline, a rotation of the Wave Generator causes a relative movement of the Flexspline to the Circular Spline.

Compared to Harmonic Drive® Gears with an elliptical Wave Generator, the three tooth engagement areas of the Triangle technology result in higher torsional stiffness under load.
