As servo technology has evolved-with manufacturers creating smaller, yet better motors -gearheads have become increasingly essential companions in motion control. Finding the optimum pairing must consider many engineering considerations.
• A servo motor working at low rpm operates inefficiently. Eddy currents are loops of electrical current that are induced within the motor during operation. The eddy currents actually produce a drag power within the engine and will have a greater negative impact on motor performance at lower rpms.
• An off-the-shelf motor’s parameters might not be ideally suited to run at a minimal rpm. When an application runs the aforementioned electric motor at 50 rpm, essentially it isn’t using all of its obtainable rpm. Because the voltage continuous (V/Krpm) of the electric motor is set for an increased rpm, the torque continuous (Nm/amp)-which is certainly directly linked to it-is definitely lower than it requires to be. As a result, the application requirements more current to drive it than if the application form had a motor particularly made for 50 rpm. A gearhead’s ratio reduces the electric motor rpm, which is why gearheads are occasionally called gear reducers. Using a gearhead with a 40:1 ratio,
the electric motor rpm at the input of the gearhead will be 2,000 rpm and the rpm at the output of the gearhead will be 50 rpm. Operating the electric motor at the bigger rpm will allow you to avoid the concerns

Servo Gearboxes provide freedom for how much rotation is achieved from a servo. Many hobby servos are limited by just beyond 180 degrees of rotation. Most of the Servo Gearboxes utilize a patented exterior potentiometer to ensure that the rotation amount is independent of the gear ratio installed on the Servo Gearbox. In such case, the small gear on the servo will rotate as much times as necessary to drive the potentiometer (and therefore the gearbox result shaft) into the placement that the transmission from the servo controller calls for.
Machine designers are increasingly turning to gearheads to take benefit of the most recent advances in servo electric motor technology. Essentially, a gearhead converts high-speed, low-torque energy into low-speed, high-torque output. A servo engine provides extremely accurate positioning of its output shaft. When both of these devices are paired with each other, they promote each other’s strengths, providing controlled motion that is precise, robust, and reliable.

Servo Gearboxes are robust! While there are high torque servos available that doesn’t suggest they are able to compare to the strain capability of a Servo Gearbox. The small splined result shaft of a normal servo isn’t lengthy enough, large enough or supported well enough to take care of some loads even though the torque numbers look like appropriate for the application. A servo gearbox isolates the strain to the gearbox result shaft which is supported by a set of ABEC-5 precision ball bearings. The external shaft can withstand intense loads in the axial and radial directions without transferring those forces to the servo. Subsequently, the servo runs more freely and is able to transfer more torque to the output shaft of the gearbox.
