Mitsubishi HC-BH0336LW4-S1 30W AC Servo Motor for JUKI KE2070 KE2080 FX-3 Z-Axis Placement-head Vertical Motion

The Mitsubishi HC-BH0336LW4-S1 is a compact 30W AC servo motor identified by JUKI part number 40044534. It is commonly used as a Z-axis motion component in compatible JUKI KE2070, KE2080, and selected FX-3 SMT placement-machine configurations. Its primary role is to control precise vertical movement of the placement head during component pickup, transfer, and placement.

Stable Z-axis movement is essential for maintaining repeatable nozzle height, controlled component contact, smooth head operation, and reliable PCB assembly. When the original motor develops abnormal noise, vibration, unstable positioning, intermittent movement, or recurring servo alarms, replacement with a correctly matched unit can help restore production performance.

Original new and tested original used options are available for preventive maintenance, emergency repair, machine refurbishment, and spare-parts inventory. Before ordering, buyers should confirm the motor label, JUKI part number, connector, shaft, cable direction, and machine configuration.

The combination of model HC-BH0336LW4-S1, rated output 30W, and JUKI part number 40044534 is consistently used by SMT-parts references to identify this Z-axis servo motor.

The Z-axis motor performs frequent acceleration, deceleration, positioning, and stopping during every placement cycle. Continuous production, mechanical resistance, contamination, cable fatigue, and incorrect alignment may gradually affect motor performance.

A motor-related alarm should be diagnosed carefully because similar symptoms can also be caused by the servo driver, feedback cable, coupling, guide mechanism, power connection, or head assembly.

The following conditions may indicate that the motor or surrounding Z-axis system requires inspection:

• Z-axis servo alarm appears during startup.
• Placement head cannot complete origin return.
• Vertical head movement becomes slow or irregular.
• Motor produces unusual bearing or rubbing noise.
• Z-axis vibration increases during acceleration.
• Nozzle pickup height becomes inconsistent.
• Component placement height becomes unstable.
• The machine stops intermittently during production.
• Motor temperature rises unusually quickly.
• Axis movement fails after extended operation.
• Positioning alarms return after machine restart.
• One head has repeated pickup or placement errors.
• Motor response becomes delayed or intermittent.
• The shaft or coupling shows visible wear.
• Connector or cable insulation is damaged.

These symptoms do not automatically confirm motor failure. The complete Z-axis system should be examined before replacing the motor.

The recommended solution is to install a replacement motor matching the original machine requirements:

• Mitsubishi motor model HC-BH0336LW4-S1.
• JUKI part number 40044534.
• Rated output of 30W.
• Correct Z-axis installation position.
• Matching shaft and mounting interface.
• Matching connector and cable direction.
• Compatible feedback and electrical configuration.

Selecting the correct motor helps reduce the risk of installation delays, repeated alarms, incorrect positioning, and unplanned production stoppages.

The placement-machine Z axis controls the vertical position of the nozzle and placement head. Small movement errors may affect pickup, recognition, transfer, and placement operations.

Accurate Z-axis performance supports:

• Correct nozzle approach height.
• Consistent component pickup pressure.
• Reliable lifting from carrier tape.
• Stable component transfer.
• Controlled placement onto solder paste.
• Reduced nozzle or component impact.
• Repeatable placement height.
• Lower risk of head collision.
• Smooth machine calibration.
• Improved production continuity.

A stable motor does not replace proper machine calibration, nozzle maintenance, feeder adjustment, vacuum inspection, and head-mechanism servicing. These systems must work together.

Detailed electrical values, connector pin arrangement, encoder configuration, shaft dimensions, and cable specifications should be confirmed from the original motor label, machine parts manual, or actual sample.

Do not select a servo motor only by appearance, approximate dimensions, or rated output.

• Practical for discontinued or older equipment.
• Suitable for urgent maintenance budgets.
• Original mechanical and electrical configuration.
• Available with inspection according to stock condition.

Original used motors may show scratches, installation marks, label wear, or minor cosmetic differences. These marks do not automatically indicate a functional problem.

The HC-BH0336LW4-S1 motor is used in professional SMT equipment maintenance and PCB assembly operations.

The motor operates as part of a closed-loop servo-control system. The placement-machine controller generates a movement command, and the servo system controls the motor according to the required position, speed, and movement profile.

This cycle repeats many times during normal production. Smooth motor performance, reliable feedback, correct mechanical alignment, and low movement resistance are all important.

The servo motor is only one part of the complete Z-axis system.

If the new motor is installed while another component is damaged, the machine may continue to produce alarms. The technician should inspect the entire motion system.

The required part number should be 40044534. Check the original motor, machine parts list, maintenance record, or equipment documentation.

The original motor label should show HC-BH0336LW4-S1. Similar Mitsubishi motors may have different shafts, cables, connectors, feedback systems, or installation requirements.
