Comparison of motor characteristic
| DESCRIPTION | ALUMINUM ROTOR MOTOR | COPPER ROTOR MOTOR |
|---|---|---|
| COMPARISON OF SAME POWER (AL->CU) |  |  |
| EFFICIENCY (%) | Same Efficiency | Same Efficiency |
| TORQUE (N·M) | 4~5 | 60% higher than Aluminum |
| CONDUCTIVITY (%IACS) | 63 | 100 |
| MOTOR SIZE | Large | Downsizing, Lightening |
| STRENGTH | Weak | -2.5 times higher than aluminum– Advantage to high speed operation |
| MOTOR LIFE | Short | Life extension due to copper loss reduction |
