Based on the operating data and energy-saving diagnostic report of Company X's equipment, this renovation plan involves two motors, with the following operating data:
No. | Equipment | Motor Model | Power (kW) | Quantity | Operating frequency (Hz) | Operating current (A) | Operating time per day (h) | Electricity consumption per hour (kWh) |
1 | Tableting machine | 355 | 1 | 50 | 450 | 8 |
≈224.6 | |
2 | Tableting machine | 3S-MOT.LL8 315-4BM80-Z315NON 2002IMB3 | 480 | 1 | 50 | 600 | 8 | ≈299.5 |
Upgrading the IE5 ultra-high efficiency synchronous reluctance motor system is expected to achieve the following energy-saving benefits while meeting production requirements:
355kW Motor:
The original system's annual power consumption is calculated based on 7000 hours of operation per year.
Annual Power Consumption
= Hourly Power Consumption (kWh) × 700 hours (year)
= 1,572,200 kWh
Annual Energy Savings After Retrofit
Based on equipment operation data analysis, the preliminary estimated energy saving rate is approximately 5%.
Annual Energy Savings
= Original System Annual Power Consumption × Energy Saving Rate
= 1,572,200 kWh × 5%
= 78,600 kWh
400kW Motor:
Based on the original system's annual power consumption calculation, assuming 7000 hours of operation per year:
Annual Power Consumption
= Hourly Power Consumption (kWh) × 700 hours (year)
= 2,096,500 kWh
Upgraded annual energy saving calculation
Based on equipment operation data analysis, the preliminary estimated energy saving rate is approximately 5%.
Annual Energy Saving
= Original System Annual Energy Consumption × Energy Saving Rate
= 2,096,500 kWh × 5%
= 104,800 kWh
Note: The above calculations are based on theoretical models and historical data. The actual energy saving rate needs to be compared with the meter readings before and after the upgrade.
This energy-saving technology upgrade will be carried out under the premise of ensuring that the new system meets all technical specifications of the original system, operates stably and normally, meets production process requirements, and ensures smooth operation of the company's electromechanical equipment. Its core objective is energy conservation and emission reduction.
This energy-saving upgrade is expected to involve two pieces of equipment: a 355 kW tablet press and a 480 kW tablet press.
The permanent magnet assisted synchronous reluctance motor (PMa-Syn.RM) combines the advantages of permanent magnet synchronous motors and synchronous reluctance motors, featuring high energy efficiency, high reliability, environmental friendliness, and small size. It is suitable for industrial energy saving and various mechanical equipment drive applications, and has broad market prospects.
Jiangsu Huima Technology Co., Ltd.'s permanent magnet assisted synchronous reluctance motor has been included in the "National Industrial and Information Technology Energy Saving and Carbon Reduction Technology and Equipment Recommendation Catalog (2024 Edition)," making it the only reluctance motor brand to be included in this catalog. Particularly noteworthy is that, according to the detailed description in the catalog, Huima Technology's permanent magnet assisted synchronous reluctance motor boasts energy efficiency superior to Level 1 energy efficiency.
Energy-Saving Principle:
Synchronous reluctance motors offer synchronized speed with no slip, zero rotor loss, higher efficiency, and a wider high-efficiency range.
Synchronous reluctance motor systems have excellent energy-saving performance, which comes from the following aspects:
Under identical operating conditions, data was collected using electricity meters agreed upon by both parties. First, statistical analysis was performed on the original asynchronous motor, followed by statistical analysis on the synchronous reluctance motor system.
The hourly power consumption (kWh) of the original asynchronous motor after a period of operation was calculated. After installation and commissioning, the hourly power consumption of the new synchronous reluctance motor system was calculated over the same operating period. n represents the total number of motors being modified.
Based on the on-site data collection and analysis of the existing motor operating conditions, combined with the efficiency of our company's energy-saving motors, energy-saving rate tests conducted by various testing institutions, and energy-saving feedback from some users over the past few years, the following analysis was conducted.
The original on-site motor was a low-efficiency three-phase asynchronous motor. Compared to our GB18613-2020 Level 1 energy efficiency IE5 ultra-high efficiency synchronous reluctance motor system, the rated efficiency is improved by 2%-5%.
In actual operation, the original motor was frequently not operating within its rated range, averaging around 50% load. Under these conditions, the original motor's actual operating efficiency was low. Our IE5 ultra-high efficiency synchronous reluctance motor system operates at high efficiency within a load range of 20%-120%. Under this load, the synchronous reluctance motor system's efficiency is 3%-5% higher than the original motor.
In conclusion, it is estimated that after replacing the system with our synchronous reluctance motor system, under the same operating conditions, the energy saving rate will reach approximately 5%.
Note: The above is a theoretical calculation. The actual energy saving rate is subject to the actual metering data of the renovation.
