STMicroelectronics STEVAL-IPM30B

Overview

STEVAL-IPM30B from STMicroelectronics is a compact 2500 W three-phase motor drive evaluation board built around the STGIB30M60TS-L SLLIMM™ 2nd series intelligent power module (600 V, 35 A IGBTs with short-circuit ruggedness), featuring hardware overcurrent protection, NTC-based IPM temperature monitoring, and dual current sensing options (dedicated op-amps or MCU-integrated). It targets high-efficiency field-oriented control (FOC) of PMSM/BLDC and AC induction motors in white goods and power tools.

For engineers reviewing the STEVAL-IPM30B datasheet, STEVAL-IPM30B pinout, STEVAL-IPM30B application, or STEVAL-IPM30B equivalent, this board provides validated interface circuitry for STM32-based motor control systems-including 32-pin motor control connector, Hall/encoder input support, bootstrap/snubber networks, and configurable single/three-shunt current sensing with fast analog conditioning.

Technical Context

The board implements a complete 3-phase inverter stage using the STGIB30M60TS-L IPM, which integrates gate drivers, protection logic (UVLO, smart shutdown), and internal NTC for thermal monitoring. Its control interface accepts PWM signals (six-channel: PWM-A-H/L through PWM-C-H/L) and supports emergency stop (EM_STOP) and fault reporting via SD and TSO pins.

Current feedback is conditioned through three TSV994 rail-to-rail op-amps for shunt-based sensing, with selectable gain and offset networks to deliver 1.65 V centered, 3.3 V full-scale analog outputs compatible with STM32 ADC inputs. Hall/encoder inputs are level-shifted and filtered for robust rotor position acquisition.

FAQ

Does STEVAL-IPM30B support both PMSM and induction motor control?

Yes. The board is explicitly validated for both PMSM/BLDC and three-phase induction motor (ACIM) control using field-oriented control (FOC) or scalar V/f methods. Its current sensing architecture, PWM timing resolution, and thermal protection enable stable operation across both motor types under rated 2500 W load conditions.

What STM32 development boards is STEVAL-IPM30B compatible with?

It is designed for direct mechanical and electrical interfacing with ST's STM32 motor control evaluation boards, including X-NUCLEO-IHM07M1 (based on STM32F303RE) and X-NUCLEO-IHM16M1 (STM32G431RB), via its standardized 32-pin motor control connector and matching pinout mapping for PWM, current sense, and Hall/encoder signals.

Can the current sensing be configured for single-shunt only?

Yes. The board supports both single-shunt and three-shunt configurations via jumper settings (SW1–SW4) and selectable resistor networks. Single-shunt operation uses one shunt resistor on the DC link with time-multiplexed sampling, while three-shunt employs individual phase shunts for simultaneous measurement-both routed through the same TSV994 op-amp stage.

Is hardware overcurrent protection independent of the MCU?

Yes. Overcurrent detection is implemented in hardware using comparator circuits that monitor shunt voltage against a fixed threshold. When triggered, it asserts the SD (shutdown) pin on the STGIB30M60TS-L IPM within <1 μs, forcing immediate gate disable-bypassing MCU firmware latency for fail-safe response.
