2.3.2.3 Low-Voltage Hardware Set Specification

This hardware set is dedicated for medium power (phase current < 50 A) and automotive voltage. The specifications for a low-voltage hardware and motor set are listed in Table 2-4. The hardware power stage board is dedicated for 12 V, but can be simply configured to a 42 V supply (described in documentation for the ECLOVACBLDC board). The supplied motor is targeted for 12 V.
