fico-44's Introduction

项目简介

项目名称:FICO-44
简介视频:https://www.bilibili.com/video/BV1Yh41147wo/

主控板

当前版本仍存在较大缺陷,仅供研究用
PCB工程 https://oshwhub.com/zhang_sai/44-guan-jie-qu-dong

特点:

  • 基于SIMPLE FOC实现的BLDC FOC(无电流环)控制,控制板集成控制、驱动、编码器于一体;
  • 单个关节80元左右的物料成本
  • 采用集成两级行星减速器,减速比达到30;
  • 除轴承、螺钉、螺母外,所有结构件采用3D打印,大大降低成本。

参数

  • 额定电压:16V
  • 额定功率:25W
  • 最大扭矩:1N·M(预估,可能误差较大)
  • 最高转速:80RPM
  • 峰值电流:2.5A

缺陷

  • 缺少电流环,高负载、快速运动时极易跑飞,导致当前版本可用性较差。正在考虑保持成本不会大幅上升的解决方案
  • 3D打印行星减速器的齿轮、齿圈时,打印机精度不足导致装配有问题或者运动过程中阻力过大。使用ENDER-3S打印机,PLA耗材,调教打印机到良好状态时成品率较高,摩擦力可接受。

提示

  • 3D打印的模型需要根据自己的打印机型号和状态进行动态调整后输出STL文件打印,涉及过盈配合和齿轮传动
  • 电机一定要让商家做成不带限位的,否则...
