Building a Wireless Bipolar Stepper Motor Driver Circuit Part 2

In this series we look at how to design a wirelessly controlled bipolar stepper motor driver circuit using the TB67S249FTG,EL motor drive IC and the ESP32-S3-WROOM microcontroller with WiFi and Bluetooth capabilities. In part 2 we do a demo and a deep dive into the ForceTronics Wireless Stepper Motor Driver hardware design with an emphasis on implementing the TB67S249FTG,EL Bipolar Motor Drive IC from Toshiba.

Suggestion for a future circuit: 120VAC variable voltage reduction circuit. 120VAC input and 10 to 120VAC output with the ability to handle a 1 to 3 amp load.

Thanks for the suggestion. The easiest way to do what you are asking for is to use a Variac (variable transformer). But a variac does not have a regulated output with set voltage and current limits. If you need a tightly regulated adjustable AC power signal than you are looking for an "AC Source" or "AC power supply" and they are not an easy design and would be out of my reach for a video series. Companies like Chroma and Keysight Technologies make some but they are not cheap.

A while back, I purchased a 24VAC transformer on Amazon for $15 (USD) for my RV. I installed an ecobee thermostat (With relays) in my RV and the 24VAC transformer works great. That is when we have shore power (AC) available. When Dry-Camping (No AC) the ecobee is useless, so I have to flip a switch that sets the connections back to the old fashioned (Analog) 12VDC thermostat. I was thinking of making an AC/DC inverter with an AC output set to 24VAC. I could probably put a circuit together on a PCB using a Triac, Diac, Pot, a few Resisters and Capacitors. The issue would be the exact values of them to use, which in my case would be trial and error as I do not remember the formulas to arrive at the proper values. My brain cells would not be happy at all. Once I got the 24VAC output I would see what the resistance of the Pot was and replace it with a resistor. Well it was a good idea. I could just purchase a low output 120VAC inverter and plug the 24VAC transformer into it and run it 24/7, but the batteries would not be happy with that idea. Still thinking. Thanks@@ForceTronics

IT WAS FINE UNTIL I TURNED IT OFF !!! 😭🤣 - i'll be allright ya know

[@ForceTronics]

I am confused, are you commenting on this video or some other video????
