ST: new SDK makes motor-control design faster and easier


first_img Continue Reading Previous Digi-Key: compact power measurement tool for IoT applications from QoitechNext Parasoft: support for microservice-specific protocols and message formats STMicroelectronics has further simplified development of advanced, energy-efficient motor drives on STM32 microcontrollers by harmonizing the latest STM32 PMSM FOC Software Development Kit with the STM32Cube ecosystem. The move extends opportunities for engineers to build sophisticated drives for equipment such as air conditioners, home appliances, drones, building automation, industrial machinery, medical devices, e-bikes, and many others, without needing specialized experience.Building on previous generations of ST’s Field-Oriented Control of Permanent Magnet Synchronous Motors SDK, the new version 5.0 firmware libraries align with the STM32Cube Hardware Abstraction Layer and Low Level architectures, which eases development, customization, and debugging. In addition, free access to source code gives developers extra flexibility, control, and customizability.New with MC-Workbench version 5.0, the Graphical User Interface leverages the STM32CubeMX workflow to set up the project, configure microcontroller peripherals, and generate initialization code automatically. It also lets users monitor and change control loop parameters in real time, as they develop or debug their projects.A rich selection of algorithms are included implementing popular PMSM-control techniques such as Maximum Torque Per Ampere to maximize efficiency and handle varying load conditions. Flux-Weakening control for extended speed range and feed-forward control for enhanced stability at high speeds are also included. Further features include “start-on-the-fly” to ensure smooth drive insertion when the rotor is already turning, which is often needed for outdoor fans such as in air conditioners or smoke extractors.Users can take advantage of proven, powerful SDK features including the Motor Profiler, which helps characterize most aspects of a motor quickly by automatically detecting the electrical parameters (stator resistance (Rs), inductance (Ls), and motor-voltage constant (Ke)), as well as mechanical friction and inertia. A variety of flexible motor-control strategies are also supported, including current sensing with single- or triple-shunt or isolated current sensors (ICS), rotor-position detection using encoder or Hall sensors, or sensorless control. The SDK also supports dual-motor applications, leveraging the rich analog features and multiple motor-control timers integrated in many STM32 variants.Share this:TwitterFacebookLinkedInMoreRedditTumblrPinterestWhatsAppSkypePocketTelegram Tags: Chips & Components, Tools & Software last_img read more


HIKE IN THE NEW YEAR AT STONE STATE PARK


first_imgContract: IAPark: 610117 Sioux City’s Stone Park is one of more than two dozen Iowa state parks that will host a First Day Hikes next Tuesday on New Year’s Day.The hikes are free and guided by park staff.Todd Coffelt, chief of the Iowa D-N-R’s State Parks Bureau, says hikers get the chance to experience the quiet beauty of nature in winter as well as spectacular views and a host of cultural treasures offered by Iowa’s state parks.Audio Playerhttp://kscj.com/wp-content/uploads/2018/12/HIKE.mp300:0000:0000:00Use Up/Down Arrow keys to increase or decrease volume.OC………..those resolutions” ;18Coffelt says the hikes are a great way to get outside, exercise, enjoy nature and welcome the New Year with friends and family, in addition to learning about the parks.Audio Playerhttp://kscj.com/wp-content/uploads/2018/12/HIKE2.mp300:0000:0000:00Use Up/Down Arrow keys to increase or decrease volume.OC……”a new friend” :19The Stone Park hike is for three miles and begins at 10am New Year’s Day.Participants should meet at the park entrance located 150 yards inside the east entrance off Talbot Road and Memorial Drive.last_img read more
