Submersible Pump Motors Stator Coil Lacing Machine

The Submersible Pump Motors Stator Coil Lacing Machine is designed for
binding and securing coil windings at both ends of submersible pump stators.
After coil insertion and forming, this machine firmly locks the coils inside the
stator slots, preventing coil movement, deformation, or loosening during
underwater motor operation. It ensures robust insulation fixation, enhances
stator reliability, and significantly extends the service life of submersible and
deep-well pump motors.

Main Features
Reliable Diamond-Pattern Lacing
Utilizes a strong diamond-shaped coil tying method suitable for high-slot-fill
submersible stators. Delivers high-strength, uniform binding to withstand
continuous underwater load conditions. Optimized for Pump Motor Stators,
Ideal for medium and large submersible pump motors used in borewells,
sewage pumps, irrigation pumps, and industrial water systems. Ensures firm
coil locking to prevent unwinding during pump start-up and high-pressure
water environments. Horizontal Precision Design, Features a stable frame
structure with dual crochet hook drive shafts for simultaneous upper and lower
stitching. Includes a rotational stator table with accurate positioning blocks to
maintain coil alignment. Lead Wire Protection System, Special limiting
mechanism secures the lead wires during lacing to avoid accidental binding
with thread. Protects terminal leads, ensuring clean assembly and reliable
motor performance. Fully Automated PLC Control, Uses a programmable PLC
to control mechanical movement, servo drives, frequency-controlled motors,
and pneumatic systems.
Automatically completes multiple operations: origin reset, stator indexing,
high-speed lacing, hook cutting, and return. Smart Touch-Screen Interface
Equipped with a touch HMI displaying system status, fault alarms, and
adjustable process parameters. Operators can easily modify binding speed,
indexing settings, and stator size configurations.
