发动机

A Motor is a Dynamics element that exerts a continuous force or torque on an object to which a Dynamics Body tag has been assigned.

马达是一个动力学元件，它对一个物体施加一个连续的力或力矩，动力学体标签已经被分配给了这个物体。

A Motor can be used to actuate a vehicle’s wheels or the cylinders of a conveyor, for example. In most cases, however, a moving object can be animated using normal keyframes.

例如，电动机可以用来驱动汽车的轮子或传送机的圆筒。然而，在大多数情况下，一个移动的对象可以使用普通的关键帧动画。

In contrast to its orientation, the location of a Motor in relation to the object it actuates is irrelevant. The Motor’s orientation (angle) defines the direction in which the object will move or the torque axis. Both are displayed in the Viewport in the form of a motor.

与它的方向相反，电动机的位置相对于它所驱动的物体是无关的。马达的方向(角度)定义了物体移动的方向或扭矩轴。两者都以发动机的形式在 Viewport 展出。

If necessary, make the Motor a Child object of the object so it is oriented correctly (e.g., the chassis of a car - NOT it’s rotating wheels), as in the following example (see also Connector Position):

如果有必要，将发动机设置为对象的子对象，使其正确定位(例如，汽车的底盘——而不是旋转的车轮) ，如下例所示(另见连接器位置) :

When applying torque, make sure the rotational axis of the rotating object is clearly linked to a Hinge Connector. Otherwise unusual oscillating rotational movements can result.

当施加扭矩时，确保旋转物体的旋转轴清楚地连接到铰链连接器上。否则就会产生不寻常的振荡旋转运动。

Functioning Motors can also be cloned, as in the example below:

功能马达也可以克隆，如下面的例子:

In the example above a cylinder, which is attached via a Hinge Connector is driven by a motor. These elements were placed into a Null Object and duplicated using a Cloner object. The result is a functioning conveyor belt.

在上面的例子中，通过铰链连接器连接的汽缸是由电机驱动的。这些元素被放置到一个 Null 对象中，并使用 Cloner 对象进行复制。结果就是一条正常运转的传送带。
