Sgei Automatic Coil Winding Machine, Automation Grade : Manual

A Coil Winding Machine is a specialized electromechanical device used to wind coils of wire onto a core, bobbin, or other structured forms. It is commonly used in the manufacturing of transformers, electric motors, inductors, relays, solenoids, and submersible motors.

Purpose

To precisely and consistently wind copper (or aluminum) wire into a pre-defined shape and number of turns, maintaining accuracy in tension, layering, and direction.

Key Components

1. Machine Structure

   • Mild Steel (MS) frame

   • Dimensions: Approx. 1200 mm (L) x 800 mm (W) x 1200 mm (H)

   • Ergonomically designed for seated or standing operation

2. Drive Motor

   • Siemens Brake Motor – 2 HP, 4 Pole, IE2 Efficiency

   • Ensures controlled rotation and braking during operation

3. Gearbox

   • Bonfiglioli Worm Reduction Gearbox

   • Low output RPM (20–25), high torque for steady winding

4. Counter Meter

   • AUTORICH SR5/RL/DB/1:1

   • Accurately tracks the number of coil turns

5. Winding Shaft (Farma Shaft)

   • 500 mm length with 100 mm threaded portion

   • Holds and rotates the bobbin/core for winding

6. Foot Pedal

   • Heavy-duty foot switch (15A, SPDT)

   • Provides hands-free speed control

7. Direction Control Switch

   • Forward/Reverse toggle to change winding direction as required

8. DOL Starter

   • Siemens Direct-On-Line Starter for motor protection and control

9. Submersible Winding Farma

   • Custom fixture for holding motor windings securely during operation

10. Working Principle

    1. The operator loads a bobbin or core onto the shaft.

    2. The machine is powered ON using the DOL starter.

    3. Direction is selected using the F/R switch.

    4. The wire is manually guided (or via traverse unit if semi/fully automatic).

    5. The foot pedal controls the motor speed for optimal winding.

    6. The counter tracks the exact number of turns.

    7. Once winding is complete, the machine is stopped and the coil is removed.

11. Applications

    • Submersible motor coils

    • Transformer LV & HV coils

    • Stator and rotor windings

    • Chokes and solenoids

12. Advantages

    • Precision in winding pitch and turn count

    • High repeatability and consistency

    • Compact and ergonomic design

    • Easy to operate and maintain
