Yamaha YV88X Head Motor 90K55-4W073D SMT Part
About This Yamaha YV88X Head AC Servo Motor
This is the servo unit mounted on a YV88X placement head. A head is asked to arrive at the same point again and again through a shift, and an AC servo is what makes that repeatable: a motor with position feedback built into it, run by an amplifier that keeps comparing the commanded position against the measured one and correcting whatever gap is left.
Two numbers identify the part, and they come from two different places. 90K55-4W073D is the machine maker's number for the head motor. P50B04006DXS0N is printed by the motor maker on the unit itself. One reaches it through Yamaha and the I-Pulse range, the other through the servo maker's catalogue, and both arrive at the same part.

Placement Head Motion Control & Motor Compatibility
The amplifier and the motor are a pair, not two items that can be mixed freely. A servo drive is set for a motor's feedback, for the way its rotor is built and for the current it can take, so a different unit on the same cable can leave a head that runs yet will not settle, that hunts around the target point, or that trips the drive on start-up.
That is why the model on the motor decides the replacement rather than the outside shape. Two units can share a mounting pattern and still differ inside, and a head given the wrong one shows it as placement that drifts a little more each shift.
Read the model from the unit being taken off, note the machine it sits on, and the match is settled before anything is ordered.
Testing Standards, Three-Month Warranty & Packaging
The unit is new, and it is marked as fully tested before dispatch. Three months is the figure carried for core components. What that covers, and the date it counts from, is settled with the order rather than assumed.
It ships in a carton lined with foam, which is what protects the shaft end and the connector in transit. UPS, DHL and FedEx are all available for dispatch.
Rated power, voltage, speed, torque, encoder resolution, shaft diameter and mounting dimensions are not given for this part, so none of them are quoted. Take them from the unit being replaced, or from the machine's own documentation, and they are confirmed against the part before dispatch.
Frequently Asked Questions On The 90K55-4W073D Motor
Q1: Which machine does this motor belong to?
A: The YV88X placement head. The I-Pulse range shares the same servo family.
Q2: Why are there two numbers?
A: One is the machine maker's part number, the other the motor maker's model. Both point at this unit.
Q3: Is it new or rebuilt?
A: New, and tested before dispatch.
Q4: Can a different servo of the same size be fitted?
A: Not safely. The drive is set for the motor it was paired with, so the model has to match.
Q5: What are the electrical ratings?
A: They are not stated for this part. Read them from the unit coming off.
Q6: Which courier can carry it?
A: UPS, DHL or FedEx, packed in a foam lined carton.
