The 38ZWS04 brushless DC motor is a high-performance drive motor specially designed and developed for users by Changzhou Duowei Electric Co., Ltd.
01. Industry Background
From household appliances to mechanical equipment, bolts (nails) are widely used connecting components due to their reusability. In automobiles and precision machinery, threaded connections are more widely used than riveting, press-fitting, and bonding. According to statistics, this connection method accounts for approximately 68% in the automotive manufacturing industry and approximately 42% in the precision machinery industry. Due to the large proportion of bolt (nail) usage, considerable manpower and expenses are invested in bolt tightening operations when manufacturing these devices. Particularly in the automotive manufacturing industry, among approximately 3500 bolts in a sedan, over 300 are considered important threaded connections. The assembly of parts such as engine cylinder heads, connecting rods, main bearing caps, and flywheels requires not only high efficiency but also high precision in bolt tightening torque. Therefore, promoting the mechanization and automation of this assembly operation to improve efficiency, quality, and reduce costs undoubtedly has significant technical and economic significance.
02. Torque Wrench
The torque wrench is an important assembly tool for threaded fasteners, also known as a torque wrench. It enables this operation to be labor-saving, mechanized, and automated. It is generally divided into three categories: manual torque wrenches, pneumatic torque wrenches, and electric torque wrenches. The 38ZWS04 brushless DC motor introduced here is mainly suitable for electric torque wrenches.
