Geared tripod head stepper motor is a kind of stepper motor used in the rotating base of the photographic device, which functions in reducing speed and increasing torque. The main transmission structure is assembled by a stepper motor (motor) and planetary gearbox (reducer). The planetary gearbox can adopt a satellite gearhead, cylindrical gearhead and worm gearhead as the reducer while the stepper motor adopts micro small-power stepper motors. Different geared stepper motors suit different types of intelligent tripod heads, whose technical parameters such as gear ratio, transmission noise, transmission precision, the structure of gearbox are usually customized.

Case of Customized Development Service:
Project Name: Intelligent Motorized Tripod Head
Project Background: Geared tripod heads which are applied to cameras helps to expand the scope of surveillance and further improve the use value of the camera. Under the action of the control voltage (the output voltage of the tripod head controller), the motorized tripod head can rotate horizontally and vertically for “panoramic” shooting to better capture the desired targets in a wider range.
Solution: ZHAOWEI focuses on the development of micro gearbox. It adopts a permanent magnet DC motor as the transmission mode and uses the drive gearbox consisting of worm and worm wheel as well as helical gear. This can effectively solve the problem of vibration and noise of the motorized pan-tilt head. The gap jitter may appear in the operation of the common tripod heads. But, ZHAOWEI improves the service life and optimize the gear backlash based on the finite element analysis of the tooth shape.
