If you want a simple and easy introduction to stepper motors, check out the [IMSAI Guy]’s short video where he designs a very basic stepper motor controller and packs in a lot of quick lesson… ...

Stepper motors are useful in many consumer, industrial, and military applications. Some, such as personal-transportation systems, require precise speed control. Stepper-motor controllers can be simple ...

This unipolar stepper motor driver circuit is used to drive a 12V unipolar stepper motor with a current rating of 1.25A. It uses PCA9537 IC, which is a 10-pin CMOS device that provides 4 bits of ...

The fundamental circuit shown in Figure 1 generates timing for a two-phase stepper motor from an oscillator, as well as a direction (forward or reverse) signal. Figure 2 depicts the typical timing ...

In the example shown, the motor-drive supply voltage is 5 V. Ohm’s Law is used to calculate total circuit resistance at 2.5 Ω to limit current through the winding to its 2-A maximum.

Implement the motor and accompanying rotary sensor into a motor control circuit in both hardware and software. ... Next, you will do a deep dive into stepper motor specs, operation, and commercial ...

For example, a motor with a torque of 2.3 N m at 500 rpm when used with a 3:1 gearbox will have a 6.9 N m output, but the motor’s rpm will climb to 1,500 rpm to drive the gearbox.
