Y-450-2  High Voltage Three Phase AC Motor

Brief Introduction

The Y-450-2 voltage converter motor features an oversize terminal box engineered for high-voltage isolation safety. Its enlarged interior maintains minimum 50mm phase-to-phase air gaps and 80mm creepage distances at 6kV rating, preventing arc discharge across terminals. This voltage converter motor employs porcelain insulators with ribbed surfaces ("sugar gourd" profile) to extend leakage paths by 40% versus flat surfaces, while ceramic material eliminates moisture absorption risks associated with bakelite alternatives.

Critical high-altitude adaptation increases clearance by 3% per 1000m above sea level. The design incorporates:

Grounded metal barriers between phases

Anti-corona coatings on all exposed conductors

Vibration-damped porcelain mounting preventing fracture

Validation testing confirms dielectric withstand at 2.5Uₙ + 2kV (IEC 60034-8), with partial discharge levels <5pC. For converter applications, the terminal box accommodates oversized cable lugs and surge arrestors, with dedicated ports for RTD sensors. Maintenance protocols mandate quarterly insulator inspections for microcracks and annual torque checks on M16 terminal bolts. This voltage converter motor ensures operational integrity in harsh environments where space constraints preclude conventional clearances, making it ideal for mining and marine voltage conversion systems. Critical high-altitude adaptation increases clearance by 3% per 1000m above sea level. The design incorporates: Grounded metal barriers between phases; Anti-corona coatings on all exposed conductors; Vibration-damped porcelain mounting preventing fracture

Main Technical Parameters

Why choose AIMIN Brand Y series of Motor?

The rotor of the Y Compact Frame HV Motor has high strength, high hardness, and good wear resistance and heat resistance, so it has a long service life. The motor bearing makes it work with high efficiency, but with low noise. The copper movement is not only energy efficient but also safe because the copper wire has low resistivity and good thermal and electrical conductivity. Under the unit cross-section, the copper wire has a large current-carrying capacity and a low voltage loss. In addition, good oxidation resistance can reduce the accident rate caused by harsh environments or overload use.

To meet with different clients' needs, the motors can be made into foot mounting or vertical mounting, insulation class H, double shaft ends, TH3, plateau and other situations.
