About Piller
More than 100 years of electrical machines
Piller was founded in Hamburg by Anton Piller and has had research, development and production in Osterode, Germany, since 1919.
Today the company is part of the UK industrial group Langley Holdings. In 2016 Piller’s US subsidiary acquired Active Power, a kinetic energy storage specialist. Piller is thus one of few manufacturers covering both rotary and static UPS technology.

Technology
The UNIBLOCK™ machine
All Piller rotary systems are built around UNIBLOCK™ – a synchronous motor-generator in which motor and generator windings share one stator and one brushless rotor.
The machine is balanced by hand at the factory, has a damper winding that reduces harmonics and uses its own impeller for cooling, so electric fans are usually unnecessary. Piller states a service life easily exceeding 20 years.

Testing and commissioning
Norwerk’s partner Bluecircle has in-depth pages on the topic.
