描述 Description

The STEVAL-CTM009V1 evaluation kit for motor control is designed to demonstrate the capabilities of ST Power MOSFETs based on STripFET? F7 technology. The 100 V STripFET? F7 devices (STH31*N10F7) are ideal for low voltage (up to 48?V), high current applications such as forklifts, golf carts and power tool.The STEVAL-CTM009V1 kit is composed of the STEVAL-CTM004V1, STEVAL-CTM005V1, STEVAL-CTM006V1, STEVAL-CTM008V1 boards which have to assembled together to build an inverter power stage for three-phase motors.The STEVAL-CTM004V1 power board features an insulated metal substrate (IMS), NTCs for thermal protection and decoupling gate resistors for each power MOSFET. The board mounts ST devices in the H2PAK-6 package.The driver stage is an STEVAL-CTM006V1 board with L6491 high current capability gate drivers to drive the power MOSFETs and integrated comparator for protections. The driver board includes the ST motor control connector, so you can interface the STEVAL-CTM009V1 with any ST MCU control board suitable for motor control (not included in the kit).The system also has an STEVAL-CTM005V1 bus link capacitor board used to connect the 48 VDC power source (e.g. the battery) to manage the ripple current and an STEVAL-CTM008V1 current sensing board to read the three-phase currents and DC bus current (not assembled) thanks to the on-board ICS. The internal reference for the ICSs can be overridden by providing an external reference voltage.
