Title:

YRKK Medium & High Voltage Slip Ring Three Phase Motor

Brief Introduction

The YRKK-900-8 small oil pump motor addresses critical failure modes in high-voltage systems through targeted engineering. Its shaft voltage mitigation employs insulated bearing seats and epoxy-coated fasteners to block circulating currents, preventing oil-film breakdown and bearing fluting. This pump motor integrates rigid baseplates and precision-machined end shields to suppress vibration below 50μm (<4m/s² acceleration), countering rotor imbalance or misalignment. Electromagnetic vibration sources are neutralized via balanced magnetic circuits (core lamination tolerance ≤0.05mm) and rotor dynamic balancing (G2.5 grade). For oil pump integration, the design features:

• Oil-resistant seals compatible with ISO VG 32-68 lubricants
• Axial thrust bearing reinforcement for pump impeller loads
• Pressurized oil circulation ports for auxiliary cooling

Proactive maintenance protocols include quarterly FFT spectrum analysis to detect early mechanical faults (e.g., loose balance weights, bearing spallation) and biennial insulation resistance tests (>100MΩ). The motor's encapsulated windings (Class F, 155°C) withstand voltage spikes from PWM drives, while anti-fretting coatings on shaft journals extend service intervals. Optimized for refinery pump applications, this small oil pump motor delivers operational uptime through fail-safe mechanical integrity.

It addresses common issues like shaft voltage generation, which can lead to bearing failures, by incorporating insulated bearing pads and sleeves to block current paths. Additionally, to combat excessive vibration, the motor features precision-balanced rotors and reinforced support structures, ensuring smooth operation in demanding environments. These design enhancements make it highly suitable for pump motor installations, where reliability is paramount. Regular maintenance and standardized inspections further contribute to its ability to operate safely and efficiently, minimizing downtime in production facilities. Overall, the YRKK-900-8 delivers exceptional performance, making it an ideal choice for applications like small oil pump motor in various industries.

Main Technical Parameters

Why choose AIMIN Brand YRKK series of Motor?

YRKK IP55 Slip Ring HV Motor is a product that has been proven in the market for many years, it is compact and lightweight. Because the vibration is small and the noise is low, it will not have a huge impact on the working environment. And its high efficiency and energy-saving features can also further save costs. Our motors have a variety of installation methods to meet the different needs of customers and the environmental requirements of product use. In addition, our products use high-strength bodies, which are not only tough but also impact-resistant. Anti-rust coating on the surface can further extend the service life.
