STEVAL-IEM003V1
Description
The STEVAL-IEM003V1 demonstration board is
designed to drive a low voltage/high current 3phase brushless synchronous or asynchronous
motor up to 3 kW. Typical uses for the system
include battery-powered traction system
applications or high-power tools.
The demonstration board is composed of two
stacked boards. The top layer is a power board
where the power devices are mounted on a
dedicate IMS layer, and the bottom board
includes the gate driving, current sensing and
power supply sections.
The STEVAL-IEM003V1 provides a compact
solution and efficient power dissipation thanks to
the power MOSFET used.
Thanks to the on-board MC connector, the
STEVAL-IEM003V1 can be easily interfaced with
any ST MCU control board equipped with the
same type of MC connector.
