There are more than one hundred years of history of balancing machine development. Germany’s Siemens invented motor in 1866. Four years later, Canadian Henry Martinson applied balance technology patent begins balancing adjustment industry. Dr. Franz Lawaczek brought modified balancing technology in Germany in 1907. All balancing procedures are conducted in pure mechanical balancing equipment. Adopt resonance speed of vibration system in rotor’s balancing rotate speed usually to reach the maximum amplitude. It’s insecure and has large measuring error in such method for measuring rotor balance.

Accompany with the popularity of electronic technology development and rigidity rotor balancing theory, we adopt electronic measuring technology in most balancing equipments after 1950s. Balancing machine with plane separation circuit technology effectively eliminates interactive infection between left and right sides of balancing workpiece. The appearance of hard bearing balancing machine can be recognized as a leap in balancing machine development history until 1970s. It eliminates inconvenience for the frequent dynamic adjustments of traditional soft bearing balancing machine, forms permanent bench mark balancing machine by adopting enactment of balancing dimension in static. In 1980s, piezoelectricity transducer brought another revolution to balancing machine. Balancing machine adopted such technology basically replaces soft bearing balancing machine in balancing field which is unnecessary to work in high speed. After 1990s, soft bearing balancing machine widely applied in some special fields accompany with rapid advancement of integrated circuit and computer technology.

Presently, balancing machine will enter into a new era along with microcomputer technology application. Balancing machine improves a lot in operation performance. It has integrated with various technologies such as light, electricity and machine together, as well as widely applied in many industries including electric tool, mechanism manufacture, fan, motor, paper making, textile, household apparatus, metallurgy and so forth.
