I am rebuilding a mobile robot platform.我正在重建一个移动机器人平台。 I have brushed DC motors 12VDC, Peak Current 16.9A, No-load current of 0.33A and trying to fing a motor driver.我有刷直流电机12VDC，峰值电流 16.9A，空载电流 0.33A 并试图找到电机驱动器。 Communication should be through CANbus .通讯应通过CANbus 。 This is the driver that I found LINK .这是我找到LINK的驱动程序。

Questions are:问题是：

What should I be aware of when looking for a motor driver/motor controller?寻找电机驱动器/电机控制器时应该注意什么？
Is the driver that I found ok for the motor?我找到的驱动器适合电机吗？

Take a look at the maximum current rating for the controller (Imax).查看控制器的最大额定电流 (Imax)。 This should always be larger than the amount of current the motor will need.这应始终大于电机所需的电流量。 Your motor peak current (I'm guessing that's the stall current) is 16A, but the controller is only rated for 4.5A.您的电机峰值电流（我猜这是堵转电流）为 16A，但控制器的额定电流仅为 4.5A。 If you never stall the motor, you might be fine, but if there's no fuse to protect the controller and there's a load on your motor, you'll probably fry it.如果你从不停止电机，你可能会没事，但是如果没有保险丝来保护控制器并且你的电机上有负载，你可能会炸掉它。 One thing to check is if you need rotation sensor feedback.要检查的一件事是您是否需要旋转传感器反馈。 This controller looks pretty advanced.这个控制器看起来很先进。 You might be able to find something in a lower price range for your size of motor if you don't need the controller to also collect rotation sensor input.如果您不需要控制器来收集旋转传感器输入，您也许可以找到适合您的电机尺寸的价格较低的产品。
