Low-noise gear motors refer to the gear drive equipment whose noise is less than 45dB during transmission. These low-noise electric motors are usually a kind of micro-drive gear motor with small power. The driving motor can adopt a DC motor, stepper motor, coreless motor and micro motor as the driving source while the planetary gearbox can adopt a satellite gearhead, cylindrical gearhead and worm gearhead as the reducer. ZHAOWEI Drive takes pride in providing gear motors whose noise is lower than 45dB.
Low-noise electric motors are widely used whose technical parameters can be customized by ZHAOWEI according to the applications. The customizable range includes:
Diameter: 3.4mm-38 mm
Output power: ﹤50W
Output speed: 5-1500rpm
Gear ratio: 2-2000
Output torque: 1.0gf.cm -50kgf.cm
According to the gearbox structure, the low-noise gear motors can be divided into coaxial type and two-stage cylindrical type gear motor. The micro helical gear motor of coaxial type enjoys compact structure, small size, nice shape and strong overload capacity. The transmission ratio enjoys fine classification, wide range of selection, low energy consumption, superior performance, high efficiency (up to 96%), weak vibration and low noise. The small gear motor has strong versatility. It is also easy to use and maintain, thus 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 so that it can work continuously in the corrosive, humid or other harsh environments. Two-stage cylindrical gear motors are divided into high-speed gear motors and low-speed gear motors. The high-speed gear reduction motor gets better performance when being shunted while 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 coaxial installation mode of gear motor is compact, but the axial dimension is large. Meanwhile, owing to the long intermediate axis, the axis bends greatly when it is under load, so the load concentration along the tooth width is more serious.
Low-noise gear motor features low noise, small volume, light weight, high carrying capacity, long service life, stable operation, high transmission precision, etc. It is widely used in consumer electronics, intelligent robot, 5G communication device, intelligent logistics, intelligent city, smart automobiles, flame cutting, laser cutting, CNC machine, CNC pipe bender, food packaging, automation industry, aeronautical facility, semiconductor equipment, robot, manipulator, pharmaceutical equipment, printing equipment, packaging machinery, textile machinery, parking equipment, measurement equipment, precision monitoring system, vehicle industry, automatic control system, etc.
