意法半導(dǎo)體推出低壓大功率電機(jī)應(yīng)用交鑰匙參考設(shè)計(jì)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(dòng)器參考設(shè)計(jì)提供了一款高度緊湊的解決方案，專(zhuān)為大功率電機(jī)控制應(yīng)用而設(shè)計(jì)，為開(kāi)發(fā)者打造了無(wú)需妥協(xié)的完整交鑰匙平臺(tái)，助力探索、開(kāi)發(fā)和原型驗(yàn)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(dòng)化、家電、伺服驅(qū)動(dòng)、電動(dòng)自行車(chē)、服務(wù)及自動(dòng)化機(jī)器人等應(yīng)用場(chǎng)景的伺服電機(jī)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(jìn)的 STSPIN32G4 智能電機(jī)驅(qū)動(dòng)器，支持開(kāi)發(fā)者通過(guò)單/雙/三電阻拓?fù)鋵?shí)現(xiàn)無(wú)傳感器或感應(yīng)磁場(chǎng)定向控制 (FOC)，并支持高級(jí)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(duì)24V至48V標(biāo)稱(chēng)母線(xiàn)電壓優(yōu)化的功率級(jí)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(dòng)高達(dá)2kW的三相無(wú)刷電機(jī)，使用風(fēng)扇散熱功率可達(dá)3kW。作為靈活且功能豐富的開(kāi)發(fā)平臺(tái)，其設(shè)計(jì)包含再生制動(dòng)專(zhuān)用電路及差分模式三電阻電機(jī)繞組電流檢測(cè)拓?fù)?。該平臺(tái)支持使用霍爾傳感器、增量編碼器和帶UART或SPI通信的絕對(duì)編碼器。內(nèi)置CAN收發(fā)器可通過(guò)支持穩(wěn)健的行業(yè)標(biāo)準(zhǔn)通信來(lái)簡(jiǎn)化系統(tǒng)級(jí)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(jì)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(wú)刷電機(jī)。該模塊集成了三相半橋柵極驅(qū)動(dòng)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(guò)壓保護(hù)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(jí)與STSPIN32G4采用堆疊設(shè)計(jì)實(shí)現(xiàn)極致功率密度。該功率級(jí)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(jī)性能實(shí)現(xiàn)卓越整體表現(xiàn)。集成過(guò)壓、過(guò)流、過(guò)溫保護(hù)機(jī)制確保系統(tǒng)穩(wěn)健運(yùn)行并精簡(jiǎn)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(kāi)發(fā)生態(tài)系統(tǒng)優(yōu)勢(shì)，，提供豐富的軟件庫(kù)與實(shí)例資源。意法半導(dǎo)體基于X-CUBE-MCSDK GUI的工作臺(tái)允許開(kāi)發(fā)者快速、輕松地配置電機(jī)控制固件參數(shù)（部分采用實(shí)時(shí)配置），大幅縮短產(chǎn)品上市周期并降低開(kāi)發(fā)成本。
