STEVAL-IHM031V1Three phase low voltage inverter power board for FOC and scalar motor control based on STS8DNH3LL MOSFET
The STEVAL-IHM031V1 demonstration board is designed to drive a low voltage/low-to-medium current, 3-phase brushless, synchronous or asynchronous motor. It provides a compact solution along with efficient power dissipation thanks to dual in-package power MOSFETs.
This demonstration board integrates the following functional blocks: dedicated power supply for handling bus voltage in the range of 12 V to 24 V (up to 5 A), integrated gate driving, overcurrent protection, overvoltage and overtemperature sensing, three-shunt current sensing for FOC control, single-shunt sensing for trapezoidal control, BEMF sensing and amplification (for both GE and STMicroelectronics methods) and motor control connector.
The on-board MC connector allows the demonstration board to be interfaced with any STMicroelectronics MCU control board with a dedicated connector in order to control several types of 3-phase motors (asynchronous, PMSM brushless DC and brushless AC).
- Bus voltage: 12 V - 24 V, up to 120 W
- 3-phase full bridge inverter topology
- Compact size with dual N-channel power MOSFETs
- Easily configurable for scalar and FOC motor control
- Motor current feedback via three shunt resistors
- Security functions:
overcurrent detection bus voltage monitoring temperature sensing
- RoHS compliant
