AI Technical Summary
Traditional variable frequency motor stator coil insulation design fails to systematically consider stress factors, resulting in low slot fill factor, large size, heavy weight, poor heat dissipation, and easy overheating and deterioration in the stator coil slot exit area.
The design employs a flexible insulation structure, including multi-layer insulation in the slot, outlet, end, and lead wire areas. It combines low-resistance and high-resistance anti-corona layers, optimizes the inter-turn, main insulation, and anti-corona structure, and is finely designed according to the inverter's power supply parameters.
It improves the motor slot fill factor, reduces material costs, shrinks the motor size, enhances the stator coil's discharge resistance and operational stability, and avoids overheating and deterioration in the slot outlet area.
