Introduction
Analysis of the core content of the standard
Detailed explanation of energy efficiency evaluation process
| Test phase | Power characteristics | Energy consumption composition | Key indicators |
|---|---|---|---|
| Power-on state | Basic power consumption of controller | Standby loss of electrical system | PS≤40W (example value) |
| No-load operation | Mechanical transmission system power consumption | Body movement energy consumption | ηB≥90% (excellent grade) |
| Rated load | Load work power consumption | Effective output energy | ηL reflects transmission efficiency |
Key technical requirements
Test environment control
It needs to be carried out in a constant temperature environment of 20±2℃, the equipment preheating time is ≥8 hours, and the power detection equipment error must be clearly marked in the report.
Test path specification
The standard cube path test (four gears of 250/400/630/1000mm) is adopted. The motion trajectory must include a→c→b→d→a sequential cycle, and the test speed must cover three gears of 100%, 50%, and 10% of the rated speed.
Energy efficiency index calculation model
Body energy efficiency ηB = EB/EU ×100% = (Total no-load energy consumption - Basic power-on energy consumption) /Total no-load energy consumption
Rated load energy efficiency ηL = EL/ELS ×100% = (Effective load energy consumption) /Total load energy consumption
Note: For the specific calculation formula, see Chapter 6 of the standard, which must strictly match the power curve integration interval
Implementation suggestions
Test preparation stage
- Prioritize the use of 0.5 level accuracy power analyzer
- Load installation must ensure that the center of mass offset parameters meet the requirements of GB/T12644-2001
Energy efficiency optimization direction
- Reduce the average power of power-on: optimize the standby circuit design of the control system
- Improve the ηB index: adopt a high-precision reducer and servo motor matching solution
- Improve the ηL value: strengthen the stiffness of the mechanical transmission system to reduce energy loss
Standard evolution analysis
This standard establishes a unified framework for the energy efficiency evaluation of industrial robots for the first time, making up for the deficiency of the original GB/T12642 that only focuses on performance indicators. In the future, it may add extended content such as energy efficiency classification and dynamic load testing.
