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.
