Product Specification
| High Light | lower temperature rise motor ，cool running pm motor ，F class insulation motor | ||
Heat is the primary enemy of motor insulation - every 10°C above rated temperature halves insulation life. This GREEF permanent magnet synchronous motor operates with a temperature rise of only 60K, well below the 80K limit of Class F insulation, thanks to lower copper losses and optimized cooling. The result: cooler bearings, longer insulation life, and reliable operation even in hot workshops or confined enclosures.
| Rated Power | 3-90 kW |
|---|---|
| Rated Voltage | 380V / 400V |
| Temperature Rise | ≤ 60K |
| Insulation Class | F / H |
| Ambient Temperature | -15°C to +50°C |
| Protection Class | IP55 |
| Cooling Method | IC411 / IC416 |
| Rated Frequency | 50Hz / 60Hz |
| Mounting Type | IMB3 / IMB5 / IMB35 |
For high ambient temperature sites, GREEF offers forced ventilation (IC416), higher insulation class and derating curves so the motor keeps cool and reliable in your specific environment.
