如何使用直流电机、电流传感器和 arduino uno 构建转矩控制电路

Question

I have been tasked with designing a circuit that controls the output torque of a DC motor. The requirements are that the motor should operate at one of two torque values (inputted using a toggle switch). This should be done using an arduino uno as well as a DiodeZetex 5 pin current sensor. I am unsure of how to actually fit all of the components together - specifically, I am not sure how to use the current sensor or how to 'set' the current of the motor?

Answer 1

I'm assuming you are using a DC motor with permanent ma.nets. In the datasheet there should be a torque constant km (Nm/A) . The torque M can then be calculated "ideally" with the formula M = km * I . The rest should be solvable with ohm's law and maybe some try and error.
