Zhenghua Electric has a strong R&D team and accumulated rich experience in the field of motors. Through long-term verification and continuous improvement of calculation programs, combined with a sound quality assurance system, the theoretical design values of the motor are surprisingly similar to the actual values (such as electromagnetic calculation, various strength calculations, rotor critical speed calculations, etc.), ensuring that the performance parameters of each newly designed product can fully meet the needs of customers.

The structural components of Zhenghua Motor are made of high-quality cast iron or die cast aluminum, and the structure is optimized to ensure the structural rigidity and strength requirements of the motor. The iron core of the stator and rotor is made of high-quality silicon steel plate, which has good surface insulation and low loss, making the efficiency of the motor higher.

The insulation is made of high-quality insulation materials, which complement the perfect insulation design, ensuring complete insulation without gaps, good rigidity at the end of the winding, and can withstand high switching and commutation strength. F-class insulation provides higher thermal stability and longer service life for the motor.

The general rotor adopts die casting technology to ensure stable quality and beautiful appearance. The balance technology of rotors includes static balance, dynamic balance, and overall operation balance. All Shengtai motors meet the vibration requirements of international standards, and rotor balance is closely related to the bearing life.

The design and selection of bearings and structures fully consider the motor form, force, speed, and lubrication method. Including bearings, oil seal design, and selection of grease, reliable performance and convenient maintenance. Generally, motors with a center height of 250 and below use enclosed bearings, while motors with a center height of 250 and above use open bearings. There is a non-stop oil injection and discharge device for the bearings.
