Motor Test Bench 馬達測試台 @STEM II 12 models

single micro:bit model from pack

fischertechnik

Product Description

 

An engine test bench allows certain technical data on the engine to be tested or measured. Typical data includes such values as the rpm, temperature or output. In the case of internal combustion engines such as in cars, motorcycles and trucks, this is done frequently. This allows engineers to observe the behavior of the engines at high loads or at extremely low temperatures.

For your motor it is important that it turns in the direction intended by the program.

 

Task

With your own motor test bench you see whether the connected motor is operating properly.  As long as button I1 is pressed, the motor should turn counter-clockwise.  As soon as button I2 is pressed it should turn clockwise. The motor should stop when neither of the buttons is pressed. Simultaneously a red light should indicate when the motor is turning counter-clockwise and a green light when it is turning clockwise.

The price below is for 1 model out of the 12 models STEM II pack.  If you want to build all 12 models, order the full STEM II pack instead.

 

  • All model parts can be reused and recycled for other projects and student's creative pieces.    fischertechnik is made in Germany with quality and precision.
  • No soldering.  Ideal for all ages, promote problem solving, changes on the fly as debugging and adjustment can be done instantly.    All works can be done to perfection as even the smallest adjustment can be accommodated, thanks to the complete range of mechanical/structural and electronic blocks offered by fischertechnik.
  • One of the 12 models of STEM 2.   You can now order it on its own for easy whole class lesson, without needing to pick and sort building blocks every time.  

 

Part 1 - micro:bit block commands used in the Motor Test Bench Model

To achieve fluency and competency in micro:bit coding, you really need to get a thorough understanding of each of the block catagories to be used in the Motor Test Bench Model (see part 2 below for the full code).    Fortunately, all the reference guides are available on the BBC micro:bit web site for you to get a deeper and more comprehensive understanding and mastery.

Through every fischertechnik STEM II model (12 of them), you can learn, practise, build fluency and confidence in coding.

The Motor Test Bench Model used the following micro:bit blocks.  You can click to lean more about each of the block catagories.  The links bring you directly to the respective part of the BBC micro:bit reference document site, where live codes are included for you to understand, try, and download:
