3D Wound Core Coil Winding Machine PCW-630

Bailipower Helps You Choose the Right Winding Machine and Use It More Efficiently

As global demand for energy-efficient transformers continues to grow, 3D wound core transformers are becoming increasingly popular in the power distribution industry. Compared with conventional laminated core transformers, they offer lower no-load losses, reduced noise, higher efficiency, and a more compact magnetic circuit.

High-quality transformers require not only excellent core manufacturing, but also precise and consistent coil winding. The quality of the winding process directly influences transformer performance, assembly accuracy, and long-term reliability.

Bailipower 3D Wound Core Coil Winding Machine PCW-630 is specifically designed for winding coils used in 3D wound core transformers. It is suitable for silicon steel wound core transformers, amorphous alloy wound core transformers, oil-immersed transformers, and dry-type transformers.

At Bailipower, we believe that supplying a machine is only the beginning. Our goal is to help customers choose the right winding machine and use it more efficiently, improving both production quality and manufacturing efficiency.

Why Choose the Bailipower PCW-630?

Many winding machines appear similar, but selecting the right equipment requires much more than comparing motor power or rotation speed.

Transformer designs vary considerably depending on:

• Core material

• Transformer capacity

• Operating frequency (50 Hz / 60 Hz)

• Voltage class

• Cooling method

• Insulation structure

• Manufacturing standards (IEC, IEEE, ANSI, etc.)

Because of these differences, transformers with the same kVA rating may have completely different coil dimensions.

Instead of recommending machines according to transformer capacity alone, Bailipower recommends selecting a winding machine according to actual transformer geometry.

For the PCW series, the most important parameter is the Center Distance Between Three Core Columns.

For the PCW-630, this distance is 630 mm, which defines the machine model and its applicable winding range.

This geometry-based selection method enables customers to choose equipment more accurately and reduces the risk of selecting an unsuitable machine.

Designed Specifically for 3D Wound Core Transformers

The PCW-630 is a horizontal coil winding machine developed specifically for manufacturing coils used in 3D wound core transformers.

During production, three coil workpieces are mounted on the machine simultaneously. Each coil is wound individually while maintaining the same positioning reference, improving consistency among all three coils and reducing setup time.

The machine supports both copper and aluminum conductors and can be configured for round wire or flat wire according to production requirements.

A variable-frequency drive provides smooth stepless speed regulation, ensuring stable winding quality and easy operation across different coil sizes.

Multiple Control Options for Different Manufacturing Requirements

Different transformer manufacturers require different levels of automation.

To satisfy various production requirements and investment budgets, Bailipower offers three control configurations:

• Electronic Counter Version

• PLC Control Version

• Servo CNC Version

The Electronic Counter Version provides a reliable and economical solution for standard production.

The PLC Version improves operating convenience and production management.

The Servo CNC Version offers higher positioning accuracy and advanced automation for demanding manufacturing environments.

Customers can select the configuration that best matches their production process.

Applications

The Bailipower PCW-630 is suitable for winding coils used in:

• 3D wound core transformers

• Silicon steel wound core transformers

• Amorphous alloy wound core transformers

• Oil-immersed transformers

• Dry-type transformers

• Energy-efficient distribution transformers

Recommended Maximum Coil Outside Diameter: 570 mm

The machine is recommended for winding coils with an outside diameter of up to 570 mm, making it suitable for a wide range of 3D wound core transformer applications.

Geometry-Based Machine Selection

Many manufacturers classify winding machines according to transformer capacity.

However, transformer capacity alone cannot accurately determine machine suitability.

Transformers with identical power ratings may have different coil dimensions due to differences in:

• Silicon steel or amorphous alloy cores

• Oil-immersed or dry-type construction

• Operating frequency

• Voltage ratings

• Insulation design

• National standards

For this reason, Bailipower recommends evaluating the following parameters when selecting a winding machine:

• Center Distance Between Three Core Columns

• Coil Outside Diameter

• Maximum Load Capacity

• Adjustable Clamping Distance

This engineering-oriented selection method provides more reliable results than selecting equipment based solely on transformer capacity.
