Title:

YVFE2 250M-4 Variable Frequency Low Voltage AC Motor

Brief Introduction

Engineered for demanding industrial applications, the YVFE2-250M-4 is a robust squirrel cage induction motor offering reliable performance in humid or variable environments. As a 4 pole ac motor, it features enhanced insulation systems to mitigate moisture ingress risks, complying with IP54 protection standards. Its design supports multiple drying methods, including external heating (e.g., controlled warm-air circulation) and low-voltage current drying-ideal for restoring insulation resistance without disassembly.

Optimized thermal management ensures safe operation under extended drying cycles, with winding temperatures maintained below 85°C. The ac motor integrates reinforced sealing at terminal boxes and inspection covers, preventing condensation during downtime. Compatible with iron-loss or current-based drying techniques, it simplifies field maintenance in high-humidity settings like pumps, compressors, and ventilation systems.

For rapid reactivation post-exposure to moisture, its accessible windings facilitate efficient drying via controlled external heat sources or low-voltage excitation. This 4 pole ac motor delivers consistent torque and efficiency (IE3 standard), minimizing energy losses while ensuring operational continuity in challenging climates. As a ac motor, it features enhanced insulation systems to mitigate moisture ingress risks, complying with IP54 protection standards.

Main Technical Parameters

Why choose Simo Brand YVFE2 series Motor?

YVFE2 Variable Frequency LV Motor adopts an all-copper motor, so it not only has high operating efficiency and strong power but also can achieve efficient heat dissipation. The fan cooling system can keep the temperature of the motor from being too high when it runs for a long time. It can maintain stable output at both high and low frequencies. The high-hardness shaft is finely manufactured, so it is more durable. In order to achieve excellent voltage shock resistance, it has relatively high requirements on the selection of materials and selection of magnet wires, so the performance of insulating materials is better than that of ordinary motors.
