The three main factors that affect the quality of the motor: material quality, quality system, and personnel quality. 1. Founder Motor adopts special proportioned steel materials to reduce energy loss by 20% in terms of copper loss, iron loss, and mechanical loss, thereby greatly improving overall efficiency. The expected service life of a motor can exceed 20 years, and it turns out that many motors have been used for more than 100 years. 2. Winding is the second cause of damage to the motor. After long-term operation, the insulation system including the enameled package on the winding copper wire begins to be damaged and a short circuit occurs. The motor can be re-wound without severely reducing the efficiency of the motor. Shengtai motor winding adopts class F insulation at 155°C. The lower the operating temperature of the motor, the longer the life of the insulation system. Usually when the motor is running at full load, the temperature can be reduced to 60-80°C, while the low-quality motor can exceed 90°C. Theoretically, if the operating temperature is reduced by 10-15°C, the winding life and refueling time can be doubled. 3. The key components of the motor: the bearing is the component that is prone to failure of the motor. Shengtai's bearings are purchased from SKF, NSK, C&U, TMZ and other companies, while a small number of them are purchased from other major bearing manufacturers in Shanghai. Ensure the reliability of the bearing. 4. The stator is laminated by silicon steel sheets, which are a kind of low-loss thin steel sheets with insulation. These silicon steel sheets must have the same performance and be as thin as possible to make the magnetic field strength reach the value. 5. The rotor shaft, fan, and junction box are all designed by Shengtai.
