Low-noise gear motors denotes the gear drive equipment whose noise is <45 dB during transmission; these low-noise electric motors are typically a type of micro-drive gear motor with small power. The drive motor can adopt a DC motor, and micro motor as the drive source, while the planetary gearbox can adopt a planetary gearhead, cylindrical gearhead, and worm gearhead as the reducer. ETONM takes pride in providing gear motors whose noise is <45dB. Low-noise electric motors are extensively used whose technical parameters can be customized by ETONM based on the applications.
Based on the gearbox structure, low-noise gear motors can be categorized into the coaxial type and two-stage cylindrical type. The micro helical gear motor of the coaxial type has a compact structure, small size, excellent shape, and strong overload capacity. The transmission ratio has fine classification, a broad range of selection, low energy consumption, excellent performance, high efficiency (up to 96%), weak vibration, and low noise. The small gear motor has strong versatility. Besides, it is easy to use and maintain, thereby resulting in low maintenance costs. Moreover, the new type of micro gear motor adopts a new-type sealing device for good protection performance and strong adaptability to the environment to work continuously in corrosive, humid, or other harsh environments. Two-stage cylindrical gear motors are categorized into high-speed gear motors and low-speed gear motors. The high-speed gear reduction motor has better performance when shunted, whereas the gear on the low-speed shaft is arranged symmetrically relative to the bearing and the longitudinal load distribution is even. The radial dimension of the coaxial installation mode of the gear motor is compact, but the axial dimension is large. Meanwhile, owing to the long intermediate axis, the axis bends significantly when it is under load; thus, the load concentration along the tooth width is more serious.
