Flat Wire Motor Stator Electric Heating & Coating_Stator Varnish Coating_Insulation Coating of Motor Stator

Flat wire stator insulation coating is critical to enhance winding dielectric performance and operational reliability of automotive electric drive motors.

HOLS Automation’s customized non-standard electric heating and coating equipment realizes uniform stator heating, automated insulation coating and curing treatment. The system adopts precise temperature closed-loop control, paired with dynamic dispensing units to guarantee consistent coating thickness. Built with full-process data traceability, it satisfies IATF 16949 specifications and supports prototype testing and serial production for electric drive Tier 1 manufacturers.

The external stator clamping method for varnish dripping ensures effective prevention of clamp jaw contamination.
Adopts company self-developing varnish, precise and no leakage.
The paint dripping can be automatically adjusted from 0 to 45 degrees, increasing the filling rate in the stator slots to 99%.
The core unit of the paint supply system is a constant-temperature paint storage tank.
The temperature inside the storage tank can be monitored in real time, and a low paint level alarm is provided.
Equipped with diaphragm pump, fill the raw material to the constant-temperature paint storage tank automatically.
