    Hello.
    I would like to modernize the thickness planer by equipping it with an infinitely adjustable feed. I know that inverter drives are commonly used. However, I am looking for a non-investment solution based on various components that I have. And I have a lot of different DC and AC motors as well as a lot of "strong" electronics.
    I do not know what is the power demand in such a feed and what are the possible solutions. I ask for advice.

    Maybe some reducer and gearbox.

    The mechanical part is not a problem. The thing is what engine can I use and how smoothly control its speed while maintaining rotation stability at varying loads.

    Inverter working with feedback or for dc PWM controller also with feedback.

    As for the inverter I have already written but just some PWM. I have two DC 24V 600W motors and I could possibly use it. However, is this 600W not enough and how to control it exactly, I am looking for appropriate diagrams. I also consider using both engines in the drive because they are identical.

    One 600W with a reducer is enough.

    Added after 2 [minutes]:

    But ... how to calculate the time and cost of making a power supply, a controller with speed control, then an inverter plus an encoder will come out cheaper.

    Maybe cheaper or maybe not as winter is long and I want it by next spring. Occupation for accurate winter evenings and some satisfaction. I got this planer for free and will be used several times a year. However, the duplicate drive itself will be useful for other planned devices.

    Hello.
    Still such a question in the subject. Looking through the resources, I found the motor from the washing machine on the plate is 330 / 550W or could such a motor manage? I have a controller for it on the TDA1085 with a potentiometer for speed control. It is a system with a tacho generator and keeps the rotation quite stable. However, I have no idea what the power demand of such a feed is, maybe some colleague has access to such a planer where the feed is operated by a separate engine and can check it.

    Thanks to colleague for saying. I accept criticism with this washing machine idea really poorly thought out. On the other hand, a rather obvious solution with an easily transferable gearbox will be used, because after consulting a professional carpenter it is completely sufficient and without cost as I have everything at my disposal.

Topic summary

The discussion revolves around upgrading a thickness planer with an infinitely adjustable feed system using available components, particularly focusing on DC and AC motors. The user seeks advice on power requirements and control methods for the feed mechanism. Suggestions include using a reducer and gearbox, employing inverter drives with feedback, and utilizing PWM controllers for speed regulation. The user has two DC 24V 600W motors and considers their adequacy for the task. A standard power demand for such feeds is noted to be around 0.75kW, with recommended speeds of 4-19m/min. The conversation also touches on the feasibility of using a washing machine motor with a TDA1085 controller for speed control, although concerns about power and stability arise. Ultimately, the user decides to pursue a gearbox solution, leveraging existing resources.
