Squirrel Cage Type Motor

Title:

YKK-560-4 Medium & High Voltage Three Phase AC Motor

Brief Introduction

Precision Acoustic Engineering
Meeting GB/T 10069.1-2019 and IEC 60034-9:2021 standards, the YKK-560-4 squirrel cage type motor undergoes rigorous noise measurement at 0.5m axial/1m radial positions. Its optimized design addresses mechanical noise through C3-clearance bearings and high-temperature lubrication, while electromagnetic noise is minimized via sinusoidal windings (30% harmonic reduction) and precisely skewed rotor slots. This motor implements structural enhancements including vibration-damping bases (≤500N/mm stiffness) and noise-absorbing material in cooling shrouds (≥20mm thickness, achieving 3-5dB noise reduction).

Preventive Design for Acoustic Optimization
Structural enhancements include vibration-damping bases (≤500N/mm stiffness) and acoustic foam-lined shrouds (≥20mm thickness, 3-5dB reduction). Manufacturing controls enforce ≥3MPa stator core pressure and <0.1% porosity rotor casting. The squirrel cage type motor's air-gap uniformity control (≤±5% variation) minimizes 100Hz electromagnetic noise through laser-aligned concentricity (≤0.05mm).

Proactive Manufacturing Controls
Critical processes ensure stator core integrity (≥3MPa pressing force) and rotor casting density (<0.1% porosity). Air-gap uniformity (≤±5% variation) is maintained through laser-aligned concentricity (≤0.05mm tolerance), effectively eliminating 100Hz electromagnetic noise. The squirrel cage type motor's diagnostic protocols feature impulse voltage testing (3kV/0.1s duration) and current imbalance monitoring (<3% deviation), enabling early fault detection. Post-repair validation confirms compliance within 3-5dB(A) of no-load levels under operational conditions.
