Internal Encoders for Drive Technology Motor Feedback Systems for servo motors Synchronous servo motors are predestined for all applications requiring accuracy and dynamics. They thus suit optimally for converter operation. Motor Feedback Systems are essential components in drive systems to ensure optimal control characteristics - in particular for dynamic axes, smooth speed controls and for positioning accuracy. They thus make a significant contribution to the performance of the whole plant. Application specific requirements Installation The small size of the motors means every millimeter...

Motor Feedback Systems for servo motors Servo motors are characterized by their high dynamics and performance. These features are only reached if the servo converter can control the motor optimally. This requires high-performance sensors such as Kübler’s Motor Feedback Systems.

Internal Encoders for Drive Technology Internal encoders for asynchronous motors Asynchronous motors are increasingly used in applications where the available space is limited. In response to this requirement, drives are becoming ever more compact. To reduce the length, Kübler provides magnetic, bearingless encoders, which can also be integrated customer specifically in the motor. A scope of delivery tailored to customer requirements and comprising sensor head, magnetic ring and shielding (against magnetic effects from the brake) is provided for such purpose. This modular system consisting...

Bearingless encoders as 100 % integration in asynchronous motors Kübler offers an innovative solution here. It has made the asynchronous motor – the world’s most common electrical drive – even smarter and more compact. Thanks to the individually integrated magnetic sensor solution, the dimensions of an asynchronous motor are now significantly reduced – this saving space and costs above all. Smart technology will also make these motors fit for the future. Evaluated data for condition monitoring and predictive maintenance are available.

External Encoders for Drive Technology External encoders for asynchronous motors Asynchronous motors are the all-rounders amongst electrical drives. For every requirement there is a drive and for every drive there is a suitable Kübler encoder for mounting outside the motor. Whether as a fan motor in a small 63 size, or as a geared motor in a 225 size, asynchronous motors place special demands on encoders, above all when it comes to mechanical and electrical ruggedness. Because of their robust technology Sendix encoders prove themselves, especially in harsh environmental conditions....

Incremental encoders for mounting on asynchronous motors The incremental Sendix encoders are available in many versions, with the suitable connection variant for almost every field of application, or as economically optimized versions. Both approaches have one in common – their compact construction.

External Encoders for Drive Technology Absolute encoders for mounting on asynchronous motors The absolute Sendix encoders – available both as singleturn and multiturn versions - are first of all robust and highly accurate. The multiturn gear uses a purely optical sampling technology and is totally insensitive to magnetic fields. Moreover, the first stage is mounted on two ball bearings and underlines the robust construction of these encoders.

Absolute encoders for mounting on asynchronous motors without mechanical gear The patented Intelligent Scan Technology™, which won several awards, is the core of these absolute Sendix encoders. These optical encoders include all singleturn and multiturn functions on an OptoASIC, therefore ensuring in the same time a very high reliability and a high resolution. The multiturn version reaches a 24 bit resolution. Its outstanding feature is its wear-free functionality thanks to the optical sensor without mechanical gear.
