Engineered for industrial durability, the motor features a frame size range of H355-630, covers a power spectrum of 185-2800kW, and supports pole configurations of 4/6/8/10/12 poles—adapting to diverse heavy-duty power needs. Unlike conventional high-voltage motors, the YRKK series emphasizes user-centric design: its modular structure simplifies installation, reduces maintenance time, and lowers operational downtime, making it a cost-effective choice for long-term industrial use. Whether in high-temperature, dusty, or humid environments, the motor maintains stable performance, laying a solid foundation for uninterrupted industrial operations.
The YRKK High Voltage Electric Motor is optimized for energy efficiency, with precision-wound stator and rotor windings that minimize energy loss—critical for industries seeking to cut operational costs. Its robust mechanical design ensures low vibration (≤0.1mm/s at full load) and low noise (≤85dB at 1-meter distance), complying with strict industrial noise pollution regulations. This efficiency-noise balance makes it suitable for both indoor workshops (e.g., manufacturing plants) and outdoor installations (e.g., open-air power stations), avoiding disruptions to workspaces or surrounding areas.
To address varied environmental conditions, the YRKK series offers three specialized cooling solutions, each tested for optimal heat dissipation:
YR model: Uses IC01 self-ventilated cooling, ideal for general industrial settings with ambient temperatures between -15°C and 40°C.
YRKS model: Adopts IC81W water jacket cooling, designed for high-temperature environments (e.g., petrochemical reactors) where efficient heat removal is non-negotiable.
YRKK model: Features IC611/IC616 independent forced ventilation, perfect for enclosed or dusty spaces (e.g., underground mines) where air circulation is limited.
Each cooling system ensures the motor’s temperature remains within safe limits (≤120°C for windings) even under continuous full-load operation.
Every YRKK High Voltage Electric Motor comes standard with protective components to enhance reliability:
Two bearing temperature sensors for real-time temperature monitoring, preventing bearing damage from overheating.
Pre-installed oil filling and exit pipes, enabling easy lubrication management without disassembling the motor.
A shaft extension baffle to shield the shaft from dust, debris, and mechanical impact.
For rolling bearing versions, the motor is pre-filled with ZL-3 lithium-based grease. Recommended replacement intervals are 2000 hours for 2-pole motors and 3000 hours for 4-pole and above motors. If ambient temperature rises by 10°C, the grease life and replacement interval are halved—allowing users to plan maintenance proactively and avoid unexpected failures.
The YRKK High Voltage Electric Motor’s versatility and durability make it a staple in key industrial sectors, where it powers critical machinery and ensures operational stability.
In power stations, the motor drives core equipment such as boiler feed pumps and induced draft fans, leveraging its 185-2800kW power range to handle continuous heavy loads. Its ability to operate stably under voltage fluctuations (±10% of rated voltage) ensures uninterrupted electricity generation. In water plants, it powers large centrifugal pumps for water intake, treatment, and distribution—its corrosion-resistant housing withstands humid conditions, extending service life to 10+ years with proper maintenance.
The petrochemical industry relies on the YRKK series to drive natural gas compressors and chemical mixers. Its IC81W/IC616 cooling systems resist high temperatures (up to 60°C) and chemical fumes, while its high torque output (matched to 4/6/8 poles) handles the high-pressure demands of petrochemical processes. In metallurgy, the motor powers ore conveyors and steel rolling mills, coping with dusty environments and frequent load changes—its sealed bearing design prevents dust ingress and reduces maintenance frequency.
In mining operations, the YRKK High Voltage Electric Motor drives ore crushers and underground ventilation fans. Its IC616 cooling system avoids overheating in enclosed mines, while its rugged frame withstands mechanical shocks from ore handling. For general heavy machinery (e.g., industrial cutting machines, textile calenders), the motor’s customizable voltage (3KV/6KV/10KV) and pole count ensure compatibility with diverse equipment, eliminating the need for additional voltage converters or speed reducers.
Standard voltage options are 3KV, 6KV, and 10KV—aligning with most industrial high-voltage power grids. For non-standard voltages (e.g., 11KV for specific regional grids), our engineering team provides customized designs. Note that customized voltages may require a 1-2 week extended production lead time to ensure compliance with safety standards.
Yes, but adjustments are required. At altitudes above 1000m, reduced air density impairs cooling efficiency—we will upgrade the cooling fan or increase heat dissipation area to maintain performance. For temperatures above 40°C, we recommend the YRKS (IC81W) or YRKK (IC616) model, as their advanced cooling systems handle high temperatures better. Always share your usage environment (altitude, temperature, humidity) with our team to get a tailored solution.
Replacement intervals depend on pole count and ambient temperature:
2-pole motors: Replace ZL-3 lithium-based grease every 2000 hours (standard 25°C ambient).
4-pole+ motors: Replace every 3000 hours (standard 25°C ambient).
If ambient temperature rises by 10°C, halve the interval (e.g., 2-pole motors need grease replacement every 1000 hours at 35°C). Use only ZL-3 lithium-based grease to avoid bearing compatibility issues.
Yes. All YRKK series motors meet GB755 (China) and IEC60034-1 (global) standards, ensuring safety and performance in markets like Europe, Southeast Asia, and Africa. Our factory holds ISO 9001 quality certification, and we can provide CE, UL, or SASO certifications upon request—facilitating customs clearance and market entry for your projects.
The YRKK High Voltage Electric Motor is compatible with most heavy-duty industrial machinery, including: compressors (air, gas), centrifugal fans, water pumps (boiler feed, irrigation), ore crushers, conveyor belts, steel rolling mills, and industrial cutting machines. Its 185-2800kW power range and 4/6/8/10/12 pole options match the torque and speed needs of these applications, ensuring seamless integration and long-term reliability.
