Texas Instruments showcases new industrial technologies at SPS

- Efficient “sensorless” three-phase field oriented motor controllers (FOC) that eliminate the need for rotor sensors



TI has developed new technology that removes the need for a mechanical rotor sensor, which will be launched in early 2013, and enables more customers in more applications to implement field oriented control (FOC). This new technology enables premium motor solutions that improve motor efficiency, performance and reliability in all variable speed and load motor applications – regardless of customers’ FOC design experience.



- Reducing costs and improving reliability in industrial computing applications



The integrated features of the Stellaris ARM Cortex-M4F-based System Management Controller (SMC) will be demonstrated in an industrial PC application benefiting from reduced costs, more reliability and robust end product design. The demonstration shows how the Stellaris SMC device works over a Low Pin Count (LPC) interface with the host processor in a PC system to monitor temperature sensors and batteries while controlling multiple fans and supporting human interfaces such as a keyboard and mouse.



-Designing a safety-critical electric motor drive with a SafeTI design package



Using SafeTI design package components (Hercules™ safety microcontroller, TPS65381-Q1 safety power management IC and the DRV3201-Q1 safety motor driver), a safe electric motor drive enables the controlled movement of a circular saw for standardized safety functions used in industrial applications.



- Integrating industrial communications into designs



This demonstration integrates industrial communications (EtherCAT Slave Controller und EnDat 2.2. Master) on a standard Sitara ARM AM335x microprocessor, optimizing the cycle time from signal acquisition to LED strobe with user interaction. A programmable logic controller (PLC)-based capture and control of the LED strobe on a rotating disc automatically controls position and speed. This demonstration shows what is possible for PLC, drives, sensors and industrial communication and also shows ADC122S706, DRV8412 motor driver and TLK110 industrial Ethernet PHY with the Sitara ARM microcontroller.



- Tackling harsh temperatures with H.E.A.T.



The Harsh Environmental Acquisition Terminal (HEAT) is a data acquisition system with a complete set of TI components (SM470R1B1M-HT; SM28VLT32-HT; ADS1278-HT, OPA211-HT, OPA2333-HT, INA333-HT ,THS4521-HT, REF5025-HT, SN65HVD233-HT, SN65HVD11-HT) qualified for harsh temperature operation (-55º C to +210 º C) for industrial health monitoring systems, sensors, actuator control, downhole drilling and well monitoring.



- Solving real-life power issues with design tools and information databases



TI power experts can help customers address real-life design issues with a showcase of a broad range of solutions to solve power design challenges. WEBENCH, PowerLab and Power Stage Designer solutions that aid offline and non-isolated power designs for industrial applications are highlighted.



- Testing PH values with TI sensor products



The LMP91200EVM can be seen in a sensor demonstration that tests various liquids and provides their pH values, as required in many industrial, chemical applications. The LMP91200 pH sensor analog front end board is featured with the AM335-ICE industrial communication board, which provides Ethernet connection with several industrial communication protocol standards.
