Harmonic Drive SE

Permanent precision at a great price
The servo actuators in our BHA range are the perfect combination of highly dynamic, compact synchronous servo motors and a zero backlash gear with output bearing.

A versatile selection of gears
The servo actuators in our BHA range are the perfect combination of highly dynamic, compact synchronous servo motors and zero backlash gears with output bearings. Our servo actuators with hollow shaft are another outstanding choice thanks to their low weight, small volume, excellent torque density, long lifetime and high standards of reliability.

Economical design
An economical design and optimised production methods create a precise drive system that’s great value for money and available at standard market lead times – even in applications involving large production volumes. Not only that, but you also have numerous combinations to choose from when you’re selecting the motor winding, motor feedback system, brake, connecting cable and connector. The configuration options available for the motor winding and motor feedback system are flexible, ensuring compatibility with almost every servo controller on the market.

The biggest hollow shaft for extreme environmental conditions

Servo drives in the AlopexDrive series with central shaft consist of a synchronous servo motor – specifically designed for use in mobile applications and operation under extreme environmental conditions – along with a CPU-H gear unit with output bearing. It is available in six sizes and six gear ratios between 30 and 160 and has a maximum torque of between 9 and 647 Nm.

Central hollow shaft and tilt-rigid output bearing
Of all of its numerous features, the essential structural element of the large central hollow shaft is particularly noteworthy. This fundamental component considerably simplifies construction in many applications, resulting in considerable savings in both time and cost. The output bearing features high tilting rigidity and enables direct attachment of large payloads without additional support, in a simple and space-saving construction. Thanks to its internal structure, high safety class and corrosion protection, the series is ideally suitable for use under extreme conditions (temperature, shock, vibration). The AlopexDrive series with its symmetrical, sinusoidal, three-phase system features a very low level of operating noise and highly synchronous running characteristics.

Numerous combinations possible
The AlopexDrive features numerous configuration options that enable it to be adapted to your particular system. These include the choice of motor windings, motor feedback system and brake, as well as various sensors, cables and plug connectors. This configurational flexibility means that the system is compatible with virtually every servo controller on the market. Used under extreme environmental conditions in applications requiring exact positioning, the actuators operate extremely precisely and reliably even in narrow spaces.
 

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.

Highest power density and lifetime precision

A large hollow shaft, low weight, small volume and the combination of outstanding torque density, service life and reliability were the requirements when developing the new CanisDrive® series.

Large central hollow shaft and stiff output bearing
In addition to all features, the large central hollow shaft is to be emphasized as the essential design feature. This basic feature significantly simplifies the design of many applications and thus provides a time and cost efficient solution. The servo actuator consists of a synchronous servomotor coupled with a backlash free gear unit. The CanisDrive® series is available in eight sizes and five ratios between 50:1 and 160:1 with a maximum torque between 23 and 1840 Nm. The stiff output bearing allows the direct connection of high payloads without further support, resulting in a simple and compact design. Due to the high degree of protection and the corrosion protection, the series is ideally suited for use in harsh environmental conditions.

Many possible combinationsTo adapt to your specific application, the CanisDrive® Series offers many possible combinations when selecting the motor winding, motor feedback, brake, various sensors and cable as well as connector options. By combining the CanisDrive® Actuators with the specially adapted YukonDrive® Servo Controllers, it is possible to provide a single source supply for a pre-configured drive system tailored to suit your application. Alternatively, the flexible configuration of the actuator ensures compatibility with almost any servo controller on the market

The lightweight gear with large hollow shaft
The CPL Series lightweight gear component sets, characterised by Their low moment of inertia and lightweight design, are available in five sizes with gear ratios of 30, 50, 80, 100, 120 and 160:1 offering repeatable peak torques from 9 to 372 Nm and a power density of up to 735 Nm/kg.

In addition to the proven strain wave gear technology, CPL-2A Series is also available in Triangle Technology. Setting new standards in torsional stiffness, transmission accuracy and dynamics.

Combines lightness and dynamics
By focussing on the three individual components, reduced cross sections and optimised drill patterns, the CPL-2A Series is very lightweight. If required, the gear component sets are available as specific configurations tailored to your application. The large hollow shaft can be used to feed through supply lines or services for further axes. Due to their positioning accuracy stable machine properties with short cycle times are guaranteed.
