> Energy  efficiency

According to studies by the Central Association of the Electronics Industry (ZVEI) from January 2007, 15 % of the electricity used in industry could be saved by utilising energy-efficient electric drive technology with electronic rotation speed regulation. This only permits the flow of energy to the machine that the process requires.

This is even more important as the energy costs often make up more than 90% of the initial purchase costs of electric drives. The aspect of life-cycle costs is becoming more and more important.
The patented Bogen technology forms the basis for the innovative magnetic rotary sensors, which allows for high signal precision and performance under difficult conditions, making them ideal components in the endeavor for improved energy efficiency.

  

> Motor Feedback

Magnetic rotary sensors are already being utilised in numerous standard industrial applications for the recording of rotary speed, position, and angle.
For cost reasons, these rotary sensors are usually magnetised through procedures using set pole lengths. The disadvantages of using these procedures are considerable.
Eccentricity errors and visible magnetic joints considerably limit the precision of these procedures to ±1°.
Numerous customer applications make it increasingly necessary to achieve precision of separation of considerably less than ±0,1° and to be measured with higher resolution. Through the high graduation precision of the Bogen procedure and the capability to realise very fine pole graduation, these market demands can now be implemented in a more cost-effective manner.

 

> Large shafts

For the precise recording of rotational speed as well as of the absolute position of drives with large shafts, optical absolute or incremental sensors are usually laterally applied that are often motorised with drive belts. Due to the high load, they suffer considerable wear and tear and have to be replaced regularly, which leads to downtime for the equipment.

The optical sensors that are used are only suited for small shafts and have to undergo elaborate mechanical changes to be fitted and adjusted to the large shaft diameters. In addition, dampness, dust, and dirt during operation always mean a high risk.
Magnetic rotary sensors, on the other hard, are very robust and can be easily fitted to the large shafts. Together with the appropriate sensors, maintenance-free direct and precise measurement of the necessary motor parameters can be done very easily.

  

> Absolute Systems

The existing solutions, for example, for absolute linear systems are already being utilized for several industrial applications. For many of these applications, however, the dimensions of the gauging and evaluation units are still too large.
On the basis of its flexible magnet technology, Bogen is working with numerous customers to develop innovative magnetic codes that will allow for the assembly of more compact sensors.
