IR 公司的IRMCF343是高性能{方案}RAM的马达控制,对于高端变频电器马达控制具有低本钱和高性能的优势.IRMCF343集成了两个盘算引擎:一个是用于无传感器永磁马达控制的运动控制引擎(MCETM),另一个是8位高速MCU(8051).晶振频率最大为60MHz,内部时钟最大为128MHz,无传感器控制盘算时间典范为11us,MCETM盘算数据范围16位.本京电港论坛文章先容了IRMCF343性能优势和主要特点,方框架图和典范应用框架图,以及1700W IRMCS3043马达驱动平台主要特点和性能指标与IRMCS3043参考方案套件.

IRMCF343 is a high performance RAM based motion control IC designed primarily for appliance applications. IRMCF343 is designed to achieve low cost and high performance control solutions for advanced inverterized appliance motor control.

IRMCF343 contains two computation engines. One is Motion Control Engine (MCETM) for sensorless control of permanent magnet motors; the other is an 8-bit high-speed microcontroller (8051). Both computation engines are integrated into one monolithic chip. The MCETM contains a collection of control elements such as Proportional plus Integral, Vector rotator, Angle estimator, Multiply/Divide, Low loss SVPWM, Single Shunt IFB. The user can program a motion control algorithm by connecting these control elements using a graphic compiler. Key components of the sensorless control algorithms, such as the Angle Estimator, are provided as complete pre-defined control blocks implemented in hardware. A unique analog/digital circuit and algorithm to fully support single shunt current reconstruction is also provided. The 8051 microcontroller performs 2-cycle instruction execution (60MIPS at 120MHz). The MCE and 8051 microcontroller are connected via dual port RAM to process signal monitoring and command input. An advanced graphic compiler for the MCETM is seamlessly integrated into the MATLAB/Simulink environment, while third party JTAG based emulator tools are supported for 8051 developments. IRMCF343 comes with a small QFP64 pin lead-free package.
