As servo technology has evolved-with manufacturers making smaller, yet more powerful motors -gearheads have become increasingly essential companions in motion control. Locating the optimal pairing must consider many engineering considerations.
• A servo motor running at low rpm operates inefficiently. Eddy currents are loops of electric current that are induced within the engine during procedure. The eddy currents actually produce a drag push within the motor and will have a larger negative effect on motor efficiency at lower rpms.
• An off-the-shelf motor’s parameters may not be ideally suitable for run at a low rpm. When a credit card applicatoin runs the aforementioned motor at 50 rpm, essentially it is not using all of its available rpm. As the voltage continuous (V/Krpm) of the motor is set for a higher rpm, the torque constant (Nm/amp)-which can be directly linked 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 motor rpm, which is why gearheads are sometimes called gear reducers. Using a gearhead with a 40:1 ratio,
the engine 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 enable you to avoid the concerns
Servo Gearboxes provide freedom for just how much rotation is achieved from a servo. Many hobby servos are limited by just beyond 180 examples of rotation. Many of the Servo Gearboxes make use of a patented exterior potentiometer to ensure that the rotation quantity is independent of the gear ratio installed on the Servo Gearbox. In this kind of case, the small equipment on the servo will rotate as much times as necessary to drive the potentiometer (and therefore the gearbox output shaft) into the position 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 engine technology. Essentially, a gearhead converts high-acceleration, low-torque energy into low-speed, high-torque output. A servo electric motor provides highly accurate positioning of its output shaft. When both of these products are paired with one another, they promote each other’s strengths, offering controlled motion that is precise, robust, and dependable.
Servo Gearboxes are robust! While there are high torque servos out there that doesn’t suggest they can compare to the load capability of a Servo Gearbox. The small splined output shaft of a normal servo isn’t long enough, huge enough or supported well enough to handle some loads despite the fact that the torque numbers seem to be suitable for the application form. 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 extreme loads in the axial and radial directions without transferring those forces on to the servo. In turn, the servo runs more freely and can transfer more torque to the output shaft of the gearbox.
