Product Overview

The JUKI X Axis Motor Assembly 40000685 (Motor Model: TS4613N1020E200) is a high-precision motion control component specifically designed for JUKI KE-2050 and KE-2060 SMT pick and place machines.

This assembly is responsible for driving the placement head module along the X-axis direction, enabling accurate and high-speed horizontal positioning during SMT placement operations.

Unlike ordinary servo motors, this product is a complete X-axis motion system, integrating:

• AC servo motor

• Encoder feedback system

• Mechanical mounting structure

• Signal and power interface system

It plays a critical role in determining:

• Placement accuracy

• Motion repeatability

• Machine stability

• Overall production efficiency

In modern SMT production lines, the X-axis system is considered the core motion organ of the entire placement machine.

Why X Axis Is a Core System

In JUKI KE series machines, the X axis controls:

• Horizontal movement of placement head

• Component pickup positioning

• Fine alignment during placement

• Synchronization with Y and Z axes

The performance of the X axis directly affects:

• Placement precision (μm level)

• Machine vibration and noise

• Cycle time and throughput

• Long-term mechanical reliability

This motor assembly therefore determines whether the machine runs like new or becomes unstable over time.

Core Technical Functions

1. Precision Linear Motion Control

The TS4613N1020E200 motor provides:

• High torque output

• Smooth speed regulation

• Micro-step positioning capability

Ensuring:

• Stable X-axis movement

• No backlash or jitter

• High repeatability under long operation

Especially suitable for:

• Fine-pitch components

• High-density PCB boards

• High-speed placement lines

2. Closed-Loop Encoder Feedback System

The integrated encoder system allows:

• Real-time position feedback

• Error correction

• Motion synchronization

• Speed monitoring

This guarantees closed-loop precision control even under high-speed conditions.

3. Mechanical Integration Design

This is not just a motor, but a complete mechanical assembly, including:

• Motor body

• Shaft system

Safety Instructions & Handling Guidelines

(Based on Original Tamagawa Servo Motor Manual)

This motor assembly integrates AC servo motor and encoder. For safe operation and long-term reliability, the following professional guidelines must be followed.

1. Transportation & Installation

Improper handling may cause encoder disk damage or bearing deformation.

2. Wiring Guidelines

Power & Signal Separation

• Power lines and encoder signal lines must be routed separately.

• Never place them in the same duct.

• Prevents electrical noise interference.

Grounding

• Ground terminals must be properly connected.

• Poor grounding causes unstable feedback.

3. Prohibited Electrical Tests

Incorrect tests may cause invisible internal damage.

4. Operating Environment

5. Brake Notice

If equipped with holding brake:

• For position holding only

• Not a safety brake

• External safety system required

6. Abnormal Operation

Stop immediately if:

• Noise

• Smell

• Smoke

• Vibration

• Overheating

Cut off power and inspect.

Why This Is Not Just a Motor

This product is not a commodity motor.
It is a system-level motion component that directly determines:

• Machine accuracy

• Placement stability

• Production efficiency

• Equipment lifespan

In SMT machines, X/Y/Z axis motors are engineering-grade components, not replaceable consumer parts.

Target Customers

• SMT factories

• EMS manufacturers

• JUKI refurbishing companies

• Equipment exporters

• Maintenance service providers

• Automation integrators
