Salvaging stepper motors from floppy disk drives

In this video I show you how I removed some stepper motors from some old NEC floppy disk drives. These stepper motors are tiny and sensitive, so one has to be careful with the choice of the stepper motor driver. I show a bad and a good example just to demonstrate why it is crucial to match it with an appropriate driver. Usually, the problem is that the driver delivery too much power for these tiny motors and they simply burn down. During my test, I was able to heat up one of the motors above 100°C with the DRV8825 driver, even at its lowest current setting. On the other hand, when I used the EasyDriver circuit, I was able to hold the motor in my hand and operate it. The max temperature I registered was around 40°C only, which is quite OK in my opinion. Conclusion: use the EasyDriver with the lowest power setting for this type of stepper motors. Please don't forget to subscribe! Wiring and source code: https://curiousscientist.tech/blog/fl...
