Introduction
Standard Update and Scope Definition
GB/T 28575-2020 replaces the 2012 version of the standard. The main changes include:
- Extended frame size to 63-355 (deleted 3551/3552 types)
- Pole number range adjusted to 2P-10P
- Power coverage 0.12kW-315kW
- New mechanical inspection items and test methods

| Efficiency grade | IEC 60034-14:2018 |
Key Dimensions and Installation
Typical installation types include:
- IM 0.01-0.04
0.10-0.08 315-355 0.27 63-250 0.40 0.08-0.16 315-355 0.27 0.16
Implementation suggestions
Selection considerations:
- Power correction is required when the altitude is ＞1000m
- Special lubrication treatment is required in -15℃ environment
- The efficiency of motors above 315kW is measured by loss analysis method
Quality control points:
- Factory inspection: insulation resistance, withstand voltage test, vibration test
- Type test includes 40℃ damp heat cycle verification
- Noise test needs to distinguish between no-load/load conditions
