The is a common DC brush motor speed controller used primarily in mini lathes like the CJ0618. While a single official "full" internal schematic is rarely published by the manufacturer, it is functionally equivalent to the KBIC-120 or SCR340 series controllers. Core Specifications Input Voltage: 230 VAC (50/60 Hz). Output Voltage: 0–180 VDC. Rated Current: 12 ADC (Armature DC). A complete, official schematic for the JYMC-220BI speed

While official technical manuals are often proprietary, the "full" circuit logic generally consists of the following sections: The is a common DC brush motor speed

as its central logic component. This IC manages the feedback loop from the motor and processes signals from the adjustment potentiometers. Key control points on the board include: P1, P2, P3: Potentiometers for fine-tuning performance parameters like acceleration and transient response. MAX / MIN:
