Introduction

The 

STEVAL-IPMnM1S

 is a compact motor drive power board based on SLLIMM-nano SMD (small low-loss intelligent

 

molded 

module) product (

STIPNS1M50T-H

). 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 IPM itself consists of six MOSFETs, three high voltage half-bridge gate driver ICs and a wide range of features like

 

undervoltage lockout, smart shutdown, internal temperature sensor and NTC, overcurrent protection and internal op-amp.

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-IPMnM1S is compatible with ST’s control board based on STM32, providing a complete platform for motor control.
