Semi automatic VPI 800 0.6Mpa 100 Pa Vacuum Impregnation Equipment for motor windings
1. General Introduction
VPI is especially critical for high-voltage motors, traction motors, and applications requiring robust insulation
(e.g., automotive, industrial machinery).
The resin seals windings from moisture, chemicals, and contaminants, preventing corrosion and short circuits
caused by external agents. Vacuum impregnation equipment for motor windings serves several critical functions
to enhance the performance, durability, and reliability of electric motors. Vacuum impregnation (VPI) combines
vacuum cycles to remove air and pressure cycles to force resin into micropores, ensuring complete penetration
in a single step. This is more effective than traditional methods.
Here are the key functions based on the search results:
1.1Enhanced Insulation and Dielectric Strength:
1.2 Improved Mechanical Strength:
1.3 Superior Thermal Conductivity:
2. Typical VPI Process Steps:
• Place stator/rotor in a sealed vessel.
• Apply vacuum (e.g.,100Pa to remove air and moisture).
• Introduce resin under pressure (e.g., 0.6Mpa).
• Cure thermally to harden the resin in a curing oven.
