STEVAL-CTM011V1: 250W 3-PH Inverter BLDC or PMSM, 115 / 230 VAC

The STEVAL-CTM011V1 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 STGD5H60DF IGBTs. The board supports one-shunt and two- plus one-shunt sensing topology. You can properly set the shunt topology by populating the related shunt resistors (RS1, RS2, and RS3).

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-CTM011V1 evaluation board is compatible with a wide range of input voltages. It includes a power supply stage with the VIPER122 in fly-back 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.
