Introduction
The Submersible Motor Stator Slot Paper Inserting Machine is a highprecision, fully automated system designed exclusively for inserting insulation
paper and wedges into submersible pump motor stators. It ensures accurate
slot insulation, enhances coil protection, and improves reliability and service
life of submersible motors working under harsh underwater conditions.
Main Features
Dedicated for Submersible Motors: Specially engineered for stators used in
vertical submersible and bore, well pump motors. One-Cycle Insertion: Inserts
insulation paper or wedges into all slots in a single operation. Precision
Indexing: High-accuracy slot positioning via servo or stepper motor indexing
control. Fully Automatic Paper Processing: Paper feeding, cutting, forming,
and insertion are all servo-controlled; operator only loads/unloads stator.
Smart Touch Interface: User-friendly HMI allows easy parameter setup and
production adjustments. Automatic Forming Mold Adjustment: Mold
automatically adapts to different stator specifications without manual
recalibration. Quick Adjustment Capability: Easy changeover for different
stack heights and insulation paper width used in pump motors. Tooling
Flexibility: Supports various slot shapes commonly used in submersible motor
stators by changing tooling. High-Speed Operation: Fast insertion rate of
about 0.6 seconds per slot, delivering high output and stable quality. Low
Noise & High Automation: Simple operation, consistent quality, and quiet
working environment.
Application
Ideal for insulation processing in: Submersible Pump Motor Stators, Borewell /
Deep-well Pump Motor Stators, Sewage & Drainage Pump Motor Stators,
Agricultural & Industrial Water Pump Motor Stators
