    Hello short and about 0.55 kw engine I used this system for speed control but it works imprecisely engine under light load, has a belt attached and turns a large wheel at the machine tool with a diameter of 0.5 meter when trying to change the speed to a smaller engine slowly stops and buzzs when I turn up the volume it starts to hum louder Optimizing Single-Phase 0.55 kW Motor Speed Control for 0.5m Diameter Machine Tool Wheel and turns into a spin but too fast what's going on ..

    This system is not suitable for speed control.
    Change the motor to dc / simple or complicated controller / or 3 phase / inverter control /.

    Zbigniew, now I also know that the description of this system is not suitable, it is convincing that I can add to the regulation of single-phase motors that without load it fulfills this role.

    But you forgot that among single-phase motors there are commutator and brushless motors, and each of them should have a different speed control, so in a nutshell.

    This is a brush motor.
    Will such regulator system pass the exam as above?

    A feedback system should be introduced.

    If you need to control the rotation very precisely, in my opinion it is better to switch to a DC motor and PWM control.

    The system that can be seen in # 1 is a phase power regulator, not a rotation regulator. More suitable for a drill. It is true that speed control by regulating the engine power is, but at varying load works throughout the world.
    With a current engine, no-pressure control makes no sense.

    Zbigniew and is it possible to make feedback in this system ...

    If it is a motor without a commutator, it will be hard.
    As I wrote earlier, a 3 phase or dc motor.

    Maybe it would be good to start reading instead of writing just for writing?

Topic summary

The discussion revolves around optimizing speed control for a single-phase 0.55 kW motor used in a machine tool with a 0.5-meter diameter wheel. The user reports imprecise speed control, particularly under light load, where the motor buzzes and struggles to maintain speed. Responses suggest that the current system is inadequate for precise speed control, recommending alternatives such as DC motors with PWM control or three-phase motors with inverter control. The importance of feedback systems is emphasized, particularly for brush motors, as they require different speed control methods compared to other types. The conversation highlights the limitations of phase power regulators in varying load conditions.
