Size-T alternators are design for supplying power to vehicles with high power requirements, particularly buses. Buses in city traffic require high power output within a large speed range, which includes engine idle. T1 alternators for buses are particularly suitable for this application.

T1 alternators are available in swivel-arm design with the holding arm on the left or right, and for flexible or rigid mounting. Particularly wide rolling bearings, with a large grease supply, permit long maintenance-free periods. Special corrosion-protection measures protect the alternators against splash water and salt water during winter operation.
