Title:

HV High Efficiency AC Motor

Brief Introduction

Engineered for critical power systems, the YKS-500-2 high efficiency AC motor integrates comprehensive protection protocols to ensure operational security. Its differential protection scheme safeguards against stator phase-to-phase faults (≥1MW), while inverse-time overcurrent settings (1.2–1.4×IM) prevent thermal damage during asymmetrical loads. This motor features dedicated ground-fault monitoring (5–10A alarm, >10A trip) and negative-sequence current protection to mitigate rotor overheating risks. Advanced algorithms execute precise coordination: instantaneous short-circuit tripping for <2MW units, timed undervoltage lockouts during system instability, and inverse-time curves (standard/extreme/very inverse) for overload scenarios.

The design incorporates magnetizing loss detection (100MW+ units) and excitation failure response, with specialized rotor overload protection for generators ≥100MW. For turbines ≥200MW, reverse-power protection prevents mechanical damage during steam valve failures. Settings are optimized per industry standards: startup current calculations (Idz=KkKjxKqIM/nl), locked-rotor thresholds, and thermal memory functions. Critical thresholds include:

• Stator earth fault: 5–10A warning / >10A trip
• Undervoltage: 0.7Un recovery / 0.5Un trip
• Negative-sequence: I₂≥0.08Iₙ alarm

This high efficiency AC motor delivers fail-safe operation through layered protective relaying, maintaining integrity under grid disturbances.

The YKS-500-2 motor integrates precision engineering to eliminate stator-rotor contact risks through stringent tolerance control. Its housing features coaxiality ≤0.03mm (GB/T 13957), while rotor runout is maintained below 0.02mm via CNC machining. This motor employs hydraulic bearing mounting to achieve optimal h6/H7 fits, preventing assembly-induced misalignment. Critical thermal management embeds PT100 sensors for real-time monitoring, triggering alerts at 70°C and shutdown at 85°C to avert lubrication failure. 

For humid environments, hydrophobic coatings shield windings, reducing insulation resistance drops that cause leakage faults. The design inherently resists internal short circuits through slot liner integrity and creepage optimization. During commissioning, its low inrush current minimizes nuisance tripping, and sustained high efficiency AC motor operation lowers total line current versus conventional units-reducing baseline load on protection circuits. Proactive maintenance protocols include periodic megger testing (recommended ≥5MΩ) and thermographic inspections to preempt degradation scenarios outlined in fault trees.

Main Technical Parameters

Why choose AIMIN Brand YKS series of Motor?

AIMIN YKS series of high voltage electric AC motor is three phase squirrel cage totally enclosed asynchronous motor.
