Syntegra

The motor design is a hermetically sealed simple co-axial gearless synchronous motor (a permanent magnet, three phase drive, passively cooled design); the motors can also be used for electrical dynamic braking, and also as an active electric brake.{{citation|url = http://www.mobility.siemens.com/mobility/global/Documents/en/rail-solutions/components-and-systems/brochure-syntegra-en.pdf|title = Syntegra : The complete integration of traction, bogie and braking technology|publisher = Siemens|work = mobility.siemens.com|url-status = dead|archive-url = https://web.archive.org/web/20111006082834/http://www.mobility.siemens.com/mobility/global/Documents/en/rail-solutions/components-and-systems/brochure-syntegra-en.pdf|archive-date = 6 October 2011}} The wheelset bearings are mounted inboard and support both motor, axles and wheel. A traction link from motor to the vehicle frame transmits tractive forces.

The bogie frame has a single central cross member which supports via pivots two longitudinal beams (in a 'weighing scale' arrangement) connected to the wheelset via the primary suspension. The cross member supports the vehicle body via the secondary suspension of two outboard air springs.

In mid-2006 prototype motors rated {{convert|110|kW}}, with claimed 96% efficiency, were fitted to an ex-Munich U-Bahn vehicle for testing at the Wegberg-Wildenrath test circuit.{{citation| title = Gearless motor| date = 1 August 2006| publisher = Railway Gazette International| work = railwaygazette.com| url= https://www.railwaygazette.com/nc/news/single-view/view/gearless-motor.html}} In 2008 a train fitted with two Syntegra bogies began in-service tests on the Munich U-Bahn.{{citation| url = http://www.siemens.com/press/en/pressrelease/?press=/en/pressrelease/2008/mobility/imo200808042.htm| title = Siemens' Syntegra bogie premiers at the Munich Metro| date = 18 August 2008| publisher = Siemens}}

A {{convert|150|kW}} prototype was displayed at Innotrans (2009), the prototype bogie weight was {{convert|5.6|t}}, with a {{convert|1.6|m|in|adj=on|abbr=off}} wheelbase and a maximum axleload of {{convert|14|t}}.
