Vacuum cleaner motors, the core component of high-speed vacuum cleaner, can rotate at 90,000 rpm or higher speed. The dynamic balance of vacuum cleaner motor directly affects the vibration and service life of the motor. For this motor, Suzhou Zero Dynamic has designed and manufactured a high-speed vacuum cleaner motor assembly laser automatic correction balancing machine specifically for its high-speed dynamic balancing requirement. This balancing machine adopts the non-contact weight reduction method of laser scanning, and Zero Dynamic's self-developed balancing software integrates the laser control software, so that the bearings are not subject to any external force during balance correction, which avoids the damage that mechanical de-weighting may cause to the motor bearings and other high-precision parts. Laser balance correction can achieve precision balancing, and the residual unbalance can be controlled within 0.5mg. This laser automatic correction balancing machine also has spectrum analysis function, vibration measurement function, automatic rivet point identification function, which can assist customers in analysing the causes of dynamic balance and dynamic balance damping effect.
Suzhou Zero Dynamic Co., Ltd is a subsidiary of the listed company Jiangsu Liance Electromechanical Technology Co., Ltd (stock code: 688113), which is a high-tech enterprise integrating the R&D, manufacturing of automatic balancing machines and vibration measurement service. Its founder has been devoted to the vibration balancing and analysis of precision motors for 26 years. Since its establishment, Zero Dynamic has obtained more than 50 national patents, software copyrights and other intellectual property rights in the field of dynamic balance testing and correction technology. The company now has more than 100 models of fully automatic balancing machines, vibration testing equipment, field dynamic balancing instrument, vibration meters, performance testing machines, which are widely used in household appliances, power tools, electric motors, automobiles, aerospace, machine tools and other industries. The company has cumulatively served more than 3,000 state-owned enterprises, large-scale private enterprises and multinational enterprises, including Ecovas, Dreame, Lexy, Midea, Haier, Daikin Air-conditioning, Nidec, Robrock, Harbin Electric Corporation, Black & Decker, Greenworks and other well-known companies in the industry.
