General requirements for electric motors
Noise & vibrations level reduction
Electric motors for consumer applications especially household appliances are usually working in indoor places. Excessive vibration and noise levels associated with these applications are strongly required to be eliminated. Excessive vibrations can cause premature equipment failure. High vibration levels also increase energy consumption. High noise levels, in turn, result in a poorer living environment for personnel and family. ZGB offers a range of solutions for exceptionally smooth and quiet bearing operation.
Maintenance elimination
Consequently, electric motor’s long-term performance and maintenance free are important and critical since the repair is comparatively costly and not convenient. Thus, long bearing life is a key requirement. Low operating temperature, high quality raw material, adequate lubrication and avoiding contamination are important factors in extending bearing service life. ZGB offers a range of sealed bearings that will extend bearing service life and improve cost-effectiveness as well as reduce the total cost for the application.
Environment concerning
When it comes to the important issue of environment protection, reduced energy consumption is of ever increasing importance. ZGB states our commitment to endeavor to reduce the impact of our bearings on the environment and to maintain a safe environment for the future. In connection with its manufacture of bearings for electric motors, ZGB takes into account protection of the environment, preservation of resources and more efficient use of energy.
Avoid electric current damages
In an electric motor, stray currents can cause cratering in the bearing raceways and in the rolling element surfaces. The damages from bearing currents lead to increased noise and heat levels, reduced effectiveness of the lubricant, excessive vibration and possible bearing failure. ZGB’s high quality bearing material as well as the most advanced heat treatment and full automatic Japanese grinding and super finish machineries guarantee the bearing reliable performance and prevent bearings from early fatigue failure from current damages.
