4 Technical Data
This chapter contains the technical data and definitions of all motor sizes
and lengths of the IndraDyn T series.
4.1 Definitions
Operating Modes
Bosch Rexroth motors are documented according to the test criteria and
measuring methods of EN 60034-1. Stated technical data refers to
operating modes S1 (continuous operation) and S6 (periodic operation),
each with liquid cooling using water as the cooling medium.
