Step size and speed for common stepper/micrometer combinations.

The step sizes and maximum speeds available with a range of stepper motors and micrometer gear ratios. Three micrometer gear ratios are ranged along the columns. ThorLabs PT1 imperial micrometers are /rev (/rev are also available). The Newport HR-13 provides /rev and the bulky Newport HR-1 provides /rev. Stepper motor full step sizes are ranged along the rows. Here we list all 4 step sizes available from by Vexta (OrientalMotor.com). Each table cell lists the step sizes and theoretical maximum speeds that can be attained for a given motor/micrometer combination. The top row of each cell lists step sizes for full steps, half steps, and 1/16 steps. The bottom row of each cell lists the corresponding theoretical maximum speeds. Maximum speed assumes our OpenStage microcontroller code running at a maximum step pulse rate of 4.0 kHz (in principle this can be increased). Bold entries correspond to the combinations described in this paper.

本数据集收录了多款步进电机搭配不同千分尺传动比时的步距与最大可用速度参数。本次数据集的表格中，三种千分尺传动比沿列方向排布。ThorLabs PT1英制千分尺的传动比为每转/步，另有每转/步的规格可供选购；Newport HR-13型千分尺的传动比为每转/步，而笨重型Newport HR-1型千分尺的传动比为每转/步。步进电机的整步步距沿行方向排布，本次收录了Vexta（源自OrientalMotor.com）的全部四款步进电机的相关参数。每个表格单元格将展示指定电机与千分尺组合下的步距与理论最大速度：单元格首行依次列出整步、半步及1/16步的步距参数，单元格末行则列出对应的理论最大速度。本次计算所用的最大速度基于运行于4.0 kHz最大步进脉冲频率的OpenStage微控制器代码（理论上该脉冲频率可进一步提升）。表格中的加粗条目对应本文所探讨的电机与千分尺组合方案。
