YVF315S-4XY T1 VVVF Three-phase Asynchronous 415 Volt Motor 110kw

Brief Introduction

The SIMO YVF series is a premium range of variable-voltage variable-frequency (VVVF) three-phase asynchronous motors, purpose-engineered for modern industrial drives that demand precise speed control, high energy efficiency, and reliable long-term operation. As a flagship offering from Xi'an SIMO Motor Co., Ltd., the YVF series combines robust mechanical construction with advanced electromagnetic design optimized for inverter power supply. The featured model, YVF315S-4XY T1, is a 415 volt motor rated at 110 kW with an IP55 enclosure, Class 155 (F) insulation, and a wide operating frequency range of 30–50 Hz, making it especially well suited for Southeast Asian and international markets where 415 V three-phase power systems are standard. Each motor is manufactured under strict quality management and complies with IEC and relevant national standards, ensuring consistent performance and global interoperability.

The defining characteristic of the YVF series is its inherent compatibility with variable-frequency drives (VFDs). Unlike standard induction motors that operate at a fixed speed dictated by grid frequency, YVF motors allow stepless speed regulation across a broad range by varying the output frequency and voltage of the connected inverter. This enables operators to match motor speed precisely to process requirements-whether reducing fan airflow during low-demand periods, adjusting conveyor line speed for different products, or controlling pump output to maintain constant pressure. The result is substantial energy savings, often ranging from 20% to 50% in variable-torque applications such as fans and pumps, along with improved process control and reduced mechanical wear on driven equipment. The electromagnetic design of the YVF series incorporates specialized slot geometry, optimized winding distribution, and premium-grade electrical steel laminations to minimize harmonic losses, suppress torque ripple, and suppress the additional heating and magnetic noise commonly associated with non-sinusoidal inverter output waveforms. This ensures smooth, quiet, and cool operation even at low speeds or under sustained VFD control.

Mechanically, the YVF series is built for the harshest industrial environments. The high-strength cast iron frame provides exceptional rigidity and vibration damping, while the IC411 self-cooling configuration-with a shaft-mounted fan and optimized air ducts-maintains effective heat dissipation across the entire speed range. For very low-speed applications where shaft-driven fan cooling may be insufficient, an independent forced-ventilation option (IC416) is available to guarantee continuous thermal protection. The IP55-rated enclosure offers complete protection against dust ingress and low-pressure water jets from any direction, allowing the motors to operate reliably in dusty, humid, or washdown environments found in mining, cement, food processing, and chemical plants. Precision-engineered antifriction bearings, selected for both radial and axial load capacity, are lubricated for long service intervals and can be equipped with optional bearing temperature sensors (PT100/PTC) for condition monitoring. Every 415 volt motor in the YVF lineup undergoes a comprehensive battery of factory tests before release-including no-load running, locked-rotor, insulation resistance, high-potential withstand, and vibration testing-ensuring that each unit arrives ready for trouble-free installation and immediate service.

YR series motors find wide application across a diverse range of industries. In water and wastewater treatment, they drive variable-speed pumps that adjust output to real-time demand, cutting energy costs and reducing water hammer. In HVAC systems, they power fans and blowers whose speed modulates with building load. In mining and minerals processing, they control conveyors, feeders, and crushers with smooth acceleration that reduces belt and gearbox stress. In metallurgy, they run rolling mill tables and cooling beds at precisely regulated speeds. In the food, beverage, and packaging sectors, they serve as the prime movers for mixers, extruders, and automated production lines where synchronized speed is essential. The series also supports applications requiring constant-torque operation at low speeds, such as hoists and elevators, when configured with appropriate VFD settings and optional encoder feedback for closed-loop vector control.

Beyond the standard configuration, SIMO offers extensive customization to meet project-specific requirements. Customers can select from various voltage ratings (380 V, 400 V, 415 V, 440 V, and higher), alternative mounting arrangements (B3 foot, B5 flange, B35 combined), and a range of shaft extensions and terminal box positions. Tropicalized insulation treatments, space heaters, anti-condensation drains, and special protective coatings are available for motors deployed in hot, humid, or corrosive climates-an important consideration for customers in Thailand, Indonesia, Vietnam, and other Southeast Asian markets. Encoders, brakes, and thermal protection devices can be factory-fitted to support closed-loop control, holding, and predictive maintenance strategies. Full documentation, including English-language installation manuals, dimension drawings, test reports, and certificates of conformity, accompanies every export shipment.

When you choose a SIMO YVF series motor, you gain more than a high-quality drive product-you partner with a manufacturer with over six decades of motor engineering experience, a global distribution network, and a commitment to after-sales support. From initial selection and sizing assistance to on-site commissioning, spare parts supply, and responsive technical service, SIMO stands behind every motor it builds. Whether your application requires a single 415 volt motor for a pump upgrade or an entire fleet of VFD-driven motors for a greenfield production facility, the YVF series delivers the efficiency, flexibility, and dependability your operations demand-today and for years to come.
