The STEVAL-CTM012V1 evaluation board is a three-phase inverter based on the STSPIN32F0601Q controller, which embeds a 3-phase 600 V gate driver and an Arm® Cortex®-M0 STM32 MCU.

The power stage features STD8N60DM2 MOSFETs.

The board supports both one-shunt and two- plus one-shunt sensing topology. You can set the shunt topology by opportunely populating a set of jumpers.

Moreover, you can implement a sensorless field-oriented control (FOC). This allows driving permanent magnet synchronous motors (PMSMs) and brushless DC (BLDC) motors to cover a wide range of applications, such as refrigerator compressors, pumps, fans, and industrial appliances.

The STEVAL-CTM012V1 evaluation board is compatible with a wide range of input voltages. It includes a power supply stage with the VIPER122 in buck configuration that generates +15 V and +3.3 V supply voltages required by the application.

The companion firmware is X-CUBE-MCSDK, available for download on www.st.com, to be used with the STSW-CTM011 firmware example for compressor motors.

You can compile, debug, and configure the firmware through the STM32CubeIDE and B-STLINK-ISOL plus STLINK-V3SET.

SWD and UART TX-RX connectors are also available.
