tinkerCAD案例：16. Spin Circuit Assembly 自旋电路组装
原文
In this tutorial, you’ll learn how to make a monkey with spinning arms using the Spin Circuit Assembly, which combines a spinning hobby gearmotor with 2xAAA batteries.
在本教程中，您将学习如何使用旋转电路组件制作带有旋转手臂的猴子，该组件将旋转减速电机与 2xAAA 电池相结合。
Our model, Mister Monkey is actually made of three parts: a body, a left arm, and a right arm. Let’s check him out!
我们的模型，猴子先生实际上由三个部分组成：身体，左臂和右臂。让我们看看他！
说明
-
Rotate the camera and notice how his arms are not directly connected to his body. This is because each arm will attach directly to each side of the motor’s axle, while his body will fit around the motor’s enclosure. When the motor is powered by the battery box, his arms will pinwheel!
旋转相机，注意他的手臂没有直接连接到他的身体。这是因为每个臂将直接连接到电机轴的每一侧，而他的身体将适合电机的外壳。当电机由电池盒供电时，他的手臂会风车！
-
Click and drag the monkey to see how currently, all three parts are grouped together. We’ll keep him grouped for now to make it easier to position him relative to the circuit assembly. Eventually, though, we will ungroup these components so that they can be exported independently – that way, when you 3D print the parts, they can be positioned individually to reduce support material.
单击并拖动猴子以查看当前所有三个部分如何组合在一起。我们现在将他分组，以便更容易地相对于电路组件定位他。不过，最终，我们将取消这些组件的分组，以便它们可以独立导出 - 这样，当您3D打印零件时，它们可以单独定位以减少支撑材料。

Continue to the next step.
继续执行下一步。 -
Circuit Assemblies can be found in their own category in the Shapes Panel.
电路组件可以在“形状”面板中找到其自己的类别。
说明-
Click the Shapes Panel dropdown and select Circuit Assemblies from the list.
单击“形状面板”下拉列表，然后从列表中选择“电路装配体”。
-
Notice how for each circuit assembly, there is a corresponding Cutout.
请注意，对于每个电路程序集，都有一个相应的切口。
-
Continue to the next step to explore the Spin circuit assembly and Cutout.
继续下一步以探索自旋电路组件和切口。 -
The Spin circuit assembly consists of a few different parts: a 3D printed holder (in red), a hobby gearmotor (the yellow component), and 2 AAA batteries contained in a battery box with a built-in switch (the black component at the bottom of the holder). The hobby gear motor has a white axle that rotates when powered on. Using this circuit assembly, you can build anything with spinning parts!
旋转电路组件由几个不同的部件组成：一个 3D 打印支架（红色）、一个爱好减速电机（黄色组件）和 2 节 AAA 电池包含在带有内置开关的电池盒中（支架底部的黑色组件）。爱好齿轮电机有一个白色轴，通电时会旋转。使用此电路组件，您可以使用旋转零件构建任何东西！The Spin Cutout is a special hole that has two purposes. First, it creates a cavity for fitting the Spin circuit assembly within your design. Additionally, it is used to add holes to parts that will move when attached to the motor axles.
旋转切口是一种特殊的孔，有两个用途。首先，它创建一个空腔，用于在您的设计中安装自旋电路组件。此外，它还用于在连接到电机轴时会移动的零件上添加孔。Because the monkey consists of three separate parts, each which need to have certain features to fit nicely onto the Spin circuit assembly, we’ll need 3 corresponding Cutouts.
因为猴子由三个独立的部分组成，每个部分都需要具有某些功能才能很好地适应自旋电路组件，所以我们需要 3 个相应的切口。
