The locomotives use water ( 60 % ethylene glycol . ) cooled MITRAC TC3100 type inverters, ) rated at 2500 kW . Each converter supplies two parallel connected traction motors; The traction motors are three phase induction designs with two sets of'half'windings for each phase : an individual traction unit includes 8 four-quadrant converters ( 4QC ), and two asynchronous motors.

The motor was centrally mounted by 4 poles with the asynchronous motor which has a maximum power output of 160 kW ( 1400 Nm ) and allows the use of standard axles : ZF AV 132, and the independently sprung axle ZF RL 75 EC . Energy recovered during braking is stored in the lithium-ion batteries with a capacity of 210 kWh.

Fractional horsepower electric motors are exempt from the US Energy Policy Act of 2005 and the new EN 60034-30 : 2009 ruling of European directive 2005 / 32 / EC [ http : / / ec . europa . eu / enterprise / eco _ design / directive _ 2005 _ 32 . pdf concerning the efficiency classes of low-voltage three-phase asynchronous motors.
