HÜBNER Berlin, now Baumer Hübner, has stood for robust tacho generators for almost 70 years and still supplies a wide variety of models to machine manufacturers and spare parts in OEM quality. Even though analog tacho generators have long since been replaced by digital rotary encoders in modern control concepts, LongLife tacho generators still today stand out as an alternative due to their following properties:
Analog tachometers (tacho dynamos, DC tacho generators), usually called “tachos” for short, are devices with an output voltage proportional to the speed. They generate the output voltage by means of a generator, therefore do not require any electrical auxiliary energy and combine high signal dynamics and robustness.
In drive technology, tachos are used to record the actual speed value, for example in the following areas
