Low-noise electric transaxles found their applications in cleaning industries, production lines, service robots, and low-speed electric vehicles. The use of low-noise technology would reduce the noise generated by the equipment by 30%-50%, while performance efficiency would increase by about 15%.
Silent Cleaning Equipment
The cleaning industry continues ramping noise standards upwards for equipment in quiet areas such as shopping malls, hospitals, and hotels. 60% of mall managers put low-noise equipment depending on what excess noise can do to the customers’ purchasing willingness. Low-noise electric transaxles (electric transaxles) decrease operational noise to less than 50 decibels, which equals that of normal conversation. This bar is much lower than that of 70-80 decibels from traditional cleaning equipment and, effectively, reduces the environmental noise.
Low-noise electric transaxles from Rotontek invite high-torque motors merged in noise reducing gearboxes which carry consistent performance over a service life of well over 3000 hours. The combined noise complaint drop of nearly 80% after a medium-size shopping mall adopted cleaning vehicles with Rotontek electric transaxles. It’s especially needed in night cleaning. Noise limits are dragged down often below 50 dB in commercial complexes and high-end residential areas, against which fines may be imposed amounting to several thousand US dollars or more. Equipped with this technology, a cleaning vehicle can cover 1500 square meters of a cleaning area very efficiently at a speed of 6 kilometers per hour, consuming only 60% of the power of traditional equipment.
Low-noise Production Line
Modern factories are looking for more efficient and quieter environments to work in as much as possible, especially in the field of Automated Guided Vehicles (AGVs). Low-noise electric transaxles (electric transaxles), key components of AGVs, have become very useful in optimizing production line operations. The operating environment of a factory has a direct bearing on the work performance and satisfaction of its employees. Over 75% of line production workers stated that continuous equipment noise could distract them and cause hearing damage. Compared to conventional electric transaxles, low-noise models improve operation noise level and reduce it by more than 30%, during which time motor design is improved and noise-reducing materials are added.
Rotontek’s low-noise electric transaxle technology has given new strength to the efficiency of AGV fleets by up to 15%. One such AGV is capable of carrying about 1.5 tons of goods in an hour while working away within noise levels of less than 50 decibels. Its service life is as much as 5000 hours – almost double that of conventional forms. Such high durability minimizes the frequency of equipment replacement, which leads to savings of close to $2000 per year in maintenance costs, as well as significant dividends in return on investment. Low-noise electric transaxles also support higher load capacities and smoother operation. An AGV equipped with low-noise electric transaxles can still navigate precisely at 5 kilometers per hour with full load while keeping noise levels below 40 decibels.
Unmanned low-speed vehicle
The application of low-noise electric drive axles in unmanned cleaning vehicles, unmanned patrol vehicles, and unmanned logistics vehicles is a revolution. Mechanical drive systems are accompanied by significant mechanical noise, whereas low-noise drive axles allow vehicles to operate at a noise level close to ambient background noise. In places like hospitals and university campuses where quietness must be maintained, the presence of unmanned patrol vehicles is meant to enhance a sense of security rather than cause disturbance. Excessive vehicle noise can make people nearby feel annoyed and disrupt patients’ rest or classroom teaching. Patrol vehicles equipped with low-noise drive axles can reduce operating noise to below 50 decibels.
Excessive noise from cleaning vehicles can affect the efficiency of on-duty personnel and lead to negative perceptions of technological products. Using unmanned cleaning vehicles with low-noise electric drive axles can increase the night-shift employees’ job satisfaction by 30%. In the express delivery industry, unmanned logistics vehicles often travel through residential areas. If the vehicle noise exceeds 50 decibels during delivery, it may result in user complaints. Unmanned logistics vehicles equipped with low-noise electric drive axles operate quietly and more efficiently. Using such vehicles for delivery improves user satisfaction scores by 25% and reduces energy costs by 18%.
Silent Low-speed Electric Vehicles
The heart of the low-speed electric vehicle is its powertrain, which now relies on low-noise electric transaxles. The operating noise when vehicles use this technology is about 45 decibels, which is more than 20 percent lower than noise from regular electric vehicles. Such outstanding noise performance enables silence on golf courses where low-speed vehicles are expected to operate even under full load without producing noise. The advanced electric transaxle technology supports the ability for the vehicle to travel without any noise at a speed of 25 kilometers per hour and carry loads of up to 400 kilograms.
It also applies to community patrol cars and sightseeing vehicles. Noise generated from patrol cars at night can’t be favorable among residents but low-noise patrol cars help keep noise levels below 50 decibels. This would hence redefine efficiency in patrolling and lessen the chances of community conflicts. Noise restrictions of below 60 decibels have often been set within historical sites, theme parks, and other crowd-gathering sites. Hence a sightseeing vehicle falling under this standard can carry 10 tourists per hour, ensuring a relatively pleasing tour experience without noise disturbance.
