ST delivers turnkey reference design for low-voltage, high-power motor applications

意法半導(dǎo)體推出低壓大功率電機應(yīng)用交鑰匙參考設(shè)計方案

The EVLSERVO1 servo driver reference design from STMicroelectronics offers a highly compact solution specifically engineered for high-power motor-control applications, providing designers with a turnkey platform to explore, develop, and prototype without compromises.

EVLSERVO1伺服驅(qū)動器參考設(shè)計提供了一款高度緊湊的解決方案，專為大功率電機控制應(yīng)用而設(shè)計，為開發(fā)者打造了無需妥協(xié)的完整交鑰匙平臺，助力探索、開發(fā)和原型驗證。

Delivering 3kW in a compact (50 mm x 80 mm x 60 mm) form factor, the EVLSERVO1 offers a rich set of features for servo motor control in applications including industrial and home automation, home appliances, servo drives, e-bikes, and service and automation robots.

EVLSERVO1外形緊湊（50 mm x 80 mm x 60 mm），可提供3kW的功率，為工業(yè)與家庭自動化、家電、伺服驅(qū)動、電動自行車、服務(wù)及自動化機器人等應(yīng)用場景的伺服電機控制提供豐富功能集。

Featuring the advanced STSPIN32G4 intelligent motor driver, the EVLSERVO1 allows developers to implement sensorless or sensored field-oriented control (FOC) with one, two, or three shunts; advanced position or torque control algorithms; or six-step control modes. It combines the STSPIN32G4 with a power stage optimized for nominal bus voltages from 24V to 48V.

EVLSERVO1采用先進的 STSPIN32G4 智能電機驅(qū)動器，支持開發(fā)者通過單/雙/三電阻拓撲實現(xiàn)無傳感器或感應(yīng)磁場定向控制 (FOC)，并支持高級位置/扭矩控制算法或六步控制模式。其核心架構(gòu)將STSPIN32G4與針對24V至48V標稱母線電壓優(yōu)化的功率級深度融合。

The system drives three-phase brushless motors at up to 2kW using only the heatsink, or 3kW with a fan. It provides a flexible and feature-rich platform for system development, including dedicated circuitry to enable regenerative motor braking, and triple-shunt topology for sensing of motor winding currents in differential mode. The platform supports the use of Hall sensors, incremental encoders, and absolute encoders with UART or SPI communication. A CAN transceiver is built-in and eases system-level integration by supporting robust, industry-standard communication.

該系統(tǒng)僅使用散熱器即可驅(qū)動高達2kW的三相無刷電機，使用風(fēng)扇散熱功率可達3kW。作為靈活且功能豐富的開發(fā)平臺，其設(shè)計包含再生制動專用電路及差分模式三電阻電機繞組電流檢測拓撲。該平臺支持使用霍爾傳感器、增量編碼器和帶UART或SPI通信的絕對編碼器。內(nèi)置CAN收發(fā)器可通過支持穩(wěn)健的行業(yè)標準通信來簡化系統(tǒng)級集成。

At the heart of the EVLSERVO1, the STSPIN32G4 is a compact (9mm x 9mm VFQFPN), highly integrated and flexible SiP module for the control of three-phase brushless motors. It combines a triple half-bridge gate driver with a high-performance STM32G4 MCU, and power-management circuitry that allows it to operate from a single supply. Hardware overvoltage protection for the external MOSFET circuitry, as well as on-board bootstrap diodes are integrated, further saving external components.

設(shè)計核心STSPIN32G4是一款緊湊型（9mm x 9mm VFQFPN）、高度集成且靈活的SiP模塊，用于控制三相無刷電機。該模塊集成了三相半橋柵極驅(qū)動器、高性能STM32G4微控制器及單電源供電的電源管理系統(tǒng)，內(nèi)置外部MOSFET過壓保護電路和自舉二極管，顯著減少外圍元件需求。

The EVLSERVO1 power stage is stacked with the STSPIN32G4 for maximum overall power density. Comprising six couples of paralleled STL160N10F8 MOSFETs with very low (3.2 mΩ max) RDS(ON), its high efficiency, low heat dissipation, and improved motor performance make for exceptional overall power density. Integrated over-voltage, over-current, and over-temperature protection ensure robust operation and minimal bill of materials.

EVLSERVO1功率級與STSPIN32G4采用堆疊設(shè)計實現(xiàn)極致功率密度。該功率級配備六組并聯(lián)的STL160N10F8 MOSFET（導(dǎo)通電阻最大值僅3.2mΩ），憑借高效率、低發(fā)熱與優(yōu)化的電機性能實現(xiàn)卓越整體表現(xiàn)。集成過壓、過流、過溫保護機制確保系統(tǒng)穩(wěn)健運行并精簡物料清單。

The EVLSERVO1 eases entry into exploring and prototyping using the advanced features of the STM32 ecosystem. Designers gain access to a broad range of software libraries and examples. STMicroelectronics’ X-CUBE-MCSDK GUI-based workbench allows developers to quickly and easily configure motor-control firmware parameters – some in real time – dramatically accelerating time-to-market and reducing costs.

EVLSERVO1深度整合STM32開發(fā)生態(tài)系統(tǒng)優(yōu)勢，，提供豐富的軟件庫與實例資源。意法半導(dǎo)體基于X-CUBE-MCSDK GUI的工作臺允許開發(fā)者快速、輕松地配置電機控制固件參數(shù)（部分采用實時配置），大幅縮短產(chǎn)品上市周期并降低開發(fā)成本。

The EVLSERVO1 is available now from the eStore and ST distributors for $168.00.
