- Product Description
YVFE3 Inverter Duty AC Motor — Wide Frequency Range, High Efficiency Power Solution
Running industrial equipment at variable speeds puts real stress on motors not built for VFD control. The inverter duty ac motor YVFE3 series is engineered for exactly these conditions, covering a power range of 0.75–1000 kW with three frequency conversion options: 30–50 Hz, 5–70 Hz, or 5–100 Hz. Protection level IP55 suits harsh environments, and IEC-compliant dimensions allow straightforward installation. Bearing options include SKF, NSK, and FAG.

Production is managed under an SAP factory management system, which tracks each order from raw material intake through to shipment. An in-house R&D team handles product development and customization requests.
Certifications held include CCC, CE, ISO9001, CRCC (Ministry of Railways), CQC, UL, GOST, China Energy Saving Production Certification, and ZDHY Environmental Management System Certification. These cover both domestic Chinese market requirements and major international markets.
Common Sourcing Problems and How the YVFE3 Addresses Them
Problem | How the YVFE3 Addresses It |
Motor overheats at low speed under VFD control | IP55 protection and reinforced winding insulation across the full frequency range |
Speed range is too narrow for the application | Three frequency options: 30–50 Hz, 5–70 Hz, 5–100 Hz |
Bearing failure in dusty or wet environments | Choice of SKF, NSK, or FAG bearings to match load and environment |
Motor dimensions don't fit existing equipment | IEC-compliant mounting dimensions; custom sizing available |
Unstable torque during frequent forward/reverse cycles | Designed specifically for continuous forward/reverse operation in heavy-duty processes |
Need multiple motor brands from one source | Access to 30+ brands including ABB, Siemens, and Wolong through XCMOTOR |

Compatible Drives | Domestic and international VFDs |
The YVFE3 maintains stable output across its full power and frequency range, which is particularly relevant for processes involving frequent speed changes. Winding insulation is reinforced to handle voltage spikes common in VFD-driven systems, and the motor accepts variable frequency drives from both domestic and international manufacturers.
The wide frequency span — up to 5–100 Hz in the broadest configuration — supports precise control over acceleration and rotation speed. This helps reduce mechanical wear in applications where speed variation is continuous rather than occasional.
Manufacturing and Quality Process
Raw materials and components, including bearings from SKF, NSK, and FAG, are sourced from verified suppliers. Winding, assembly, and testing are tracked through an SAP factory management system, reducing scheduling errors and supporting on-time delivery.
Before shipment, each unit undergoes electrical performance testing, insulation resistance checks, and mechanical runout verification. Units that do not pass all checks do not leave the facility.
Industry Applications
The YVFE3 inverter duty ac motor is suited for equipment that requires continuous directional changes or variable-speed operation:
· Steel rolling — repeated forward/reverse cycles under load
· Lifting and transportation — stable torque at variable speeds
· Machine tools — precise speed control for machining accuracy
· Printing and dyeing — consistent output for fabric processing lines
· Papermaking — smooth operation through tension-sensitive processes
· Chemicals and pharmaceuticals — IP55 sealed body resists moisture and contaminants
· Textiles — wide frequency range supports different fabric speeds
It is also compatible with pumps, fans, conveyors, and compressors wherever speed adjustment is needed.
Customization Options
XCMOTOR accepts customization requests based on project-specific requirements. Available options include:
· Bearing selection — SKF, NSK, or FAG based on load and operating environment
· Dimensional adjustments — shaft length, mounting size, and frame modifications
· Frequency range — 30–50 Hz, 5–70 Hz, or 5–100 Hz
· Power rating — 0.75 kW to 1000 kW
· Shipping arrangement — sea freight, air freight, land transport, or multimodal transport

FAQ
Q: What makes a product different from a standard motor?
A: A product is designed to operate under variable frequency drive (VFD) control. It features reinforced winding insulation and thermal management to handle voltage harmonics and variable speeds that would degrade a standard motor over time.
Q: What frequency ranges does the YVFE3 support?
A: The YVFE3 supports three selectable ranges: 30–50 Hz, 5–70 Hz, and 5–100 Hz. The appropriate range depends on the speed requirements of your application.
Q: Can the YVFE3 handle frequent forward and reverse rotation?
A: Yes. The motor is specifically designed for continuous and frequent forward/reverse operation, which is common in steel rolling, lifting, and machine tool applications.
Q: Which bearings can I select, and how do I specify them?
A: SKF, NSK, and FAG bearings are available. Specify your preference when placing your order, and the team will confirm availability for your selected configuration.
Q: Does the motor meet international installation standards?
A: Yes. Mounting dimensions comply with IEC standards, making the YVFE3 compatible with standard international equipment frames.
Q: What certifications apply to this motor?
A: The YVFE3 is covered by CCC, CE, ISO9001, UL, GOST, CRCC, CQC, and China Energy Saving certifications, supporting compliance across multiple global markets.
