As servo technology has evolved-with manufacturers generating smaller, yet better motors -gearheads have become increasingly essential companions in motion control. Locating the optimal pairing must consider many engineering considerations.
• A servo engine running at low rpm operates inefficiently. Eddy currents are loops of electric current that are induced within the electric motor during operation. The eddy currents in fact produce a drag power within the motor and will have a greater negative effect on motor functionality 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 engine at 50 rpm, essentially it isn’t using most of its offered rpm. As the voltage continuous (V/Krpm) of the motor is set for an increased rpm, the torque continuous (Nm/amp)-which can be directly related to it-is lower than it needs to be. Because of this, the application needs more current to drive it than if the application had a motor specifically made for 50 rpm. A gearhead’s ratio reduces the electric motor rpm, which is why gearheads are sometimes 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 higher 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 to just beyond 180 degrees of rotation. Many of the Servo Gearboxes utilize a patented exterior potentiometer so that the rotation amount is in addition to the gear ratio set up on the Servo Gearbox. In this kind of case, the small gear on the servo will rotate as many times as necessary to drive the potentiometer (and therefore the gearbox output shaft) into the placement that the transmission from the servo controller demands.
Machine designers are increasingly turning to gearheads to take advantage of the most recent advances in servo electric motor technology. Essentially, a gearhead converts high-acceleration, low-torque energy into low-speed, high-torque output. A servo motor provides highly accurate positioning of its output shaft. When these two gadgets are paired with one another, they enhance each other’s strengths, offering controlled motion that is precise, robust, and reliable.
Servo Gearboxes are robust! While there are high torque servos in the marketplace that doesn’t suggest they can compare to the strain capacity of a Servo Gearbox. The small splined result shaft of a normal servo isn’t long enough, huge enough or supported sufficiently to handle some loads despite the fact that the torque numbers seem to be suitable for the application form. A servo gearbox isolates the load to the gearbox output shaft which is backed by a pair of ABEC-5 precision ball bearings. The external shaft can withstand intense loads in the axial and radial directions without transferring those forces on to the servo. Subsequently, the servo runs more freely and is able to transfer more torque to the result shaft of the gearbox.
