The independent research and development of industrial sewing machine needle from GRAND is with a specific energy-saving direct-drive servo motor and control system. The output power is strong and can meet the sewing machine work. It also has variety of reliable automatic controls to adjust the working status of the motor, which greatly reduce energy consumption and improve efficiency. With variable speed, quick start, precise positioning brake, installation, simple maintenance. It is the ideal advanced product of current traditional industrial sewing machine clutch motor and plugging motor, and it will help you realize direct driving of industrial sewing machine.
Energy-saving motor and clutch servo motor comparison
| NO | More features | Energy-saving servo motor | Clutch Motor |
| 1 | Exterior | Excellent, full of mechatronic design concepts | Decentralized structure, large pet |
| 2 | Labor intensity | Low. Operation simple and convenient, intelligent, operator fatigue is not easy | High |
| 3 | Efficiency | High. Output increase, the corresponding reduction product processing fees | Low |
| 4 | Vibration | Low. Longer machine life, improve the quality of work improving the environment | Large |
| 5 | Noise | Low. Longer machine life, improve the working environment | Large |
| 6 | Fever | Temperature drop of paper, reduce air conditioning costs, improve work environment | Large |
| 7 | Service | Low. Brushless servo motor, maintenance-free | cluth replacement |
| 8 | Energy | Once every province, electricity (98% of non-running power, running power 26%) | Full operation |
| 9 | Green | Copper, Iron and use less material, no wear powder | cluth replacement |
| 10 | Notwork configuration | Small. Start current, low total power consumption | Large |
| 11 | saving | Saving can be recovered within a year, consolidated return on investment for 6 months | High cost |

Return On Investment(The factory actual testing record)
| JUKI 6714 Over-lock Quantity | Working hrs / day | Clutch motor Power consumption | Grand DD motor Power consumption | working day/month | Electricity rate (CNY) | Daily saving(CNY) | Monthly saving(CNY) |
| 100 sets | 9hrs | 160kw | 27kw | 26 | 1.00 | 133.00 | 3458.00 |
Using Grand energy-saving DD servo motor, compared to clutch motor, will raise the work efficiency by 10%~25%, if the monthly salary of each sewing worker is CNY2500, then each month's saving will be 250~500 yuan, the investment will be earned back in a short term.
