STEVAL-IPMNG5Q
450 W motor control power board based on STGIPQ5C60T-HZ SLLIMM™-nano IPM

The STEVAL-IPMnG5Q is a compact motor drive power board based on SLLIMM™-nano (small low-loss intelligent molded module) 2nd series product (STGIPQ5C60T-HZ) .

It provides an affordable and easy-to-use solution for driving high power motors in a wide range of applications such as power white goods, air conditioning, compressors, power fans and 3-phase inverters for motor drives in general. 

The main characteristics of this evaluation board are small size, minimal BOM and high efficiency. It features an interface circuit (BUS and VCC connectors), bootstrap capacitors, snubber capacitor, hardware short-circuit protection, fault event signal and temperature monitoring.

It is designed to work in single- or three-shunt configuration and with triple current sensing options: three dedicated on-board op-amps, op-amps embedded on MCU or single internal IPM op-amp. The Hall/Encoder part completes the circuit.

The system is designed to achieve accurate and fast conditioning of current feedback to satisfy the typical requirements for field oriented control (FOC). 

The STEVAL-IPMnG5Q is compatible with ST’s control board based on STM32, providing a complete platform for motor control.
