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.
