LRMO-LG系列直线压电电机
Piezo Motor Company的新型直线压电电机系列在紧凑型、高精度高性能直线电机技术的设计制造方面实现了质的飞跃。
该新型直线电机系列以非常经济的成本，兼具卓越的纳米级精度和超快响应速度。
LRMO-LG系列直线压电电机
运动控制选项
Piezo Motor Company的旋转电机可提供工厂预装编码器版本或无编码器版本。亦可提供全闭环系统：运动控制通过电子驱动板实现，该驱动板旨在为用户控制提供经济的接口。
电子驱动板接口支持UART和I2C
驱动PCB支持UART和I2C接口，增强了其适应性。每块板均针对特定电机型号预编程，可实现软件可配置性、优化驱动信号并集成控制功能。用户可通过安装在电机/执行器上的可选编码器进行闭环控制，从而对电机运行进行精细调节。
带Python API的闭环系统
PMC的全新Python API允许将压电电机编码器的反馈信号传输至驱动板，从而实现闭环。可通过MicroUSB端口访问一系列丰富的Python API命令，对电机的位置和速度进行控制。
LRMO-LG系列直线电机的性能与优势
分辨率提升
控制步长仅为0.05 µm，且具备全推力和保持力，这些直线电机每毫米控制步数可达20,000步。
响应速度更快
压电电机在20微秒至30微秒内即可完成第一步并开始运动，而步进电机通常需要约5毫秒才能启动运动。
高力密度
就尺寸和重量而言，这些电机提供了卓越的力密度，尤其与步进电机和丝杠解决方案相比更具优势。
节能降本
压电电机在保持力时功耗为零，低速时功耗极低（1 mm/s时为0.06 W），从而实现非常高效率的整体占空比。
特殊性能
Piezo Motor Company的电机不受EMI和RF干扰影响，且无辐射发射，使其成为一系列敏感应用的理想选择。对于特殊应用（包括MRI），请联系我们的技术团队。
经济型设计
创新设计和专利保护技术封装在稳定的增强热塑性塑料中，使这种高性能自动化产品对OEM设备设计人员而言价格实惠。
轻量化
我们的压电电机不含铜绕组、铁芯叠片或永磁体，单位重量的功率输出显著优于电磁解决方案。这使其非常适合对重量敏感的应用。
