Supply type: for the same part number we may offer new parts (not through the brand’s authorized distributor in Taiwan), compatible parts or used parts removed from machines, depending on stock. When asking for a quote, please give the part number and tell us which you need.
Machines: YS12 / YS24 / YSM20
Why it matters: servo motors handle precise positioning of the XY axes and each head axis on Yamaha SMT machines, and they are the core of the machine’s mechanical accuracy. The Yamaha Motor Series I covers the main axis motors for the YS12, YS24 and YSM20, with the KM8-M220 series as the typical part numbers.
Common motor faults: accumulated encoder error that causes positioning drift (placement offset that slowly gets worse), a winding short that trips the overheat protection, and motor noise from bearing wear. Yamaha motor error codes are mostly E0xx, and the code helps narrow down which axis is at fault.
We quote compatible spares for the Yamaha Motor Series I. The list below helps equipment engineers confirm part numbers. When asking for a quote, tell us the machine model and the faulty axis (X / Y / Z / R).
