EVAL BOARD USER’S MANUAL
Description
The SECO−MDK−4KW−65SPM31−GEVB is a development board
for three−phase motor drives, part of the Motor Development Kit
(MDK). The board features the NFAM5065L4B Intelligent Power
Module in a DIP39 package and is rated for 400 Vdc input, delivering
continuous power in excess of 1 kW, with the capability of delivering
up to 4 kW power for a short period. The board is fully compatible
with the Universal Controller Board (UCB), based on the Xilinx
®
Zynq−7000 SoC, which embeds FPGA logic and two Arm
®
Cortex −A9 processors. As such, the system is fit for high−end
control strategies and enables operation of a variety of motor
technologies (AC induction motor, PMSM, BLDC, etc.).
