Frequently Asked Questions (FAQ)

What applications is the DQ-1G Stator Coil Inserting Machine designed for?

It is specialized for automatically inserting induction motor stator coils and slot insulation cover paper into stator slots in a single coordinated process.

What stator core dimensions are compatible with this equipment?

The machine accommodates stator inside diameters (ID) from Φ30 to Φ120 mm, outside diameters (OD) up to Φ210 mm, and core stack thicknesses from 20 to 130 mm.

What are the wire diameter and stator slot specifications?

The system supports wire diameters between 0.15 mm and 1.6 mm, and handles stator laminations configured with 12 to 48 slots.

How is the insertion motion controlled and driven?

The pushing motion is driven by a precision servo motor and ball screw assembly, managed via a Mitsubishi PLC to deliver exact stroke positioning and rapid operation.

What utilities are required to operate the DQ-1G machine?

It requires an electrical power supply of AC 380V ± 10% (50Hz) with 4 kW total power, and a clean compressed air supply with 0.5 to 0.7 MPa pressure.

Is tooling replacement difficult when changing stator sizes?

No. The machine uses an integrated line tooling design that makes replacement simple, quick, and convenient while offering solid mechanical durability and long operational life.
