2.3.2.2 Low-Voltage Evaluation Hardware Set Specification

This hardware set is dedicated for 12 V voltage and very low power
(phase current < 4 A). The specifications for a low-voltage evaluation
hardware and motor set are listed in

Table 2-3

. It is targeted first of all to

software evaluation with small motors.

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.
