Classification: 27020000 [AAB583008]
| Preferred name | 27-02 电动 |

| Definition | electrical drive is a drive with an electrical engine which is operated by an automatic control. Electrical energy is converted into mechanical kinetic energy, thereof the reverse principle of the electrical generator applies. The resulting kinetic energy exists as linear or rotary movement. The efficiency factor, the relation from submitted to supplied power, continues to grow up to 99% with the increase of the power. Main group 27020000 is structured by the classification of the electric drives according to their function principle and the specification of the operating input energy and its transformation into other appropriate forms. Furthermore there is a differentiation between control electronics and regulation electronics in particular and the assembly, service, inspection and maintenance of the electric drives in general |
