Briefings
Innomotics highlights the dynamo-electric principle, discovered by Werner von Siemens in 1866, as the foundation for modern electric motors. The article cites a specific motor installed at the Tsingtao Brewery in Qingdao in the early 1900s, which operated continuously for over 90 years. It also details Innomotics' current innovations, including the Active Vibration Control System (AVCS) and oil-lubricated rolling bearings (OLRB), which enhance reliability. The Perfect Harmony GH180 drive platform is mentioned with over 25,000 units deployed globally, demonstrating the technology's enduring value.
Key points
- The dynamo-electric principle was discovered by Werner von Siemens in 1866, enabling electric machines to generate their own magnetic field through self-excitation.
- A specific electric motor installed at the Tsingtao Brewery in Qingdao in the early 1900s operated continuously for more than 90 years, serving as a testament to the principle's reliability.
Context
This article, published by Innomotics in November 2026, explores the 160-year history of the dynamo-electric principle. It connects the 1866 breakthrough to modern industrial applications, specifically citing the Tsingtao Brewery motor and the company's current drive platforms like the Perfect Harmony GH180.
Limitations
Evidence is limited to the article's text, which focuses on historical context and company-specific innovations. Specific dates for the motor's installation are not fully confirmed beyond 'early 1900s,' and the exact operational duration beyond 90 years is stated as a fact from the source.
