What Is a Paper Inserting Machine?

A paper inserting machine (also known as a stator insulation paper inserting machine) is used to insert insulating paper into the slots of a stator core. This paper acts as a dielectric barrier between the stator core and the coil windings, preventing short circuits and improving the overall durability of the motor.

u These machines are commonly applied in the production of:

u Brushless DC motors (BLDC)

u Induction motors

u EV motors

u Servo motors

u Household appliance motors

Key Features and Benefits

1. High Precision Insertion
NIDE's paper inserting machines are designed with servo-controlled systems to ensure accurate paper positioning within the stator slots. This precision guarantees consistent insulation across all motor units.

2. Automation and Speed
Fully automatic operation reduces labor cost and increases production speed. Models can handle up to 1,200 stators per hour depending on the configuration.

3. Adaptability
The machine can be customized to suit various stator diameters and stack heights. Quick tooling changeover allows manufacturers to switch between motor types easily.

4. Defect Reduction
With advanced detection sensors and intelligent monitoring systems, faulty insertions or missing paper can be automatically identified and rejected.

5. Durability and Low Maintenance
NIDE uses high-quality components and intuitive HMI interfaces to ensure long-term reliability with minimal maintenance needs.

Applications Across Industries

Paper inserting machines are vital in multiple industries, including:

l Electric vehicles (EV)

l Home appliances (washing machines, air conditioners, etc.)

l Industrial machinery

l Power tools

Each application requires tailored stator designs, and NIDE offers specialized machines for low-noise, high-speed, or high-torque motors.
