As servo technology has evolved-with manufacturers generating smaller, yet better motors -gearheads have become increasingly essential companions in motion control. Finding the optimal pairing must take into account many engineering considerations.
• A servo electric 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 in fact produce a drag force within the engine and will have a larger 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 a credit card applicatoin runs the aforementioned engine at 50 rpm, essentially it isn’t using all of its available rpm. Because the voltage continuous (V/Krpm) of the motor is set for a higher rpm, the torque continuous (Nm/amp)-which is definitely directly linked to it-is definitely lower than it requires to be. As a result, the application needs more current to operate a vehicle it than if the application had a motor particularly made for 50 rpm. A gearhead’s ratio reduces the engine rpm, which explains why gearheads are occasionally 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 engine at the higher rpm will allow you to avoid the concerns

Servo Gearboxes provide freedom for just how much rotation is achieved from a servo. Most hobby servos are limited to just beyond 180 degrees of rotation. Most of the Servo Gearboxes use a patented external potentiometer so that the rotation quantity is in addition to the equipment ratio set up on the Servo Gearbox. In such case, the small equipment on the servo will rotate as much times as essential 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 benefit of the most recent advances in servo motor technology. Essentially, a gearhead converts high-quickness, low-torque energy into low-speed, high-torque output. A servo electric motor provides extremely accurate positioning of its result shaft. When both of these devices are paired with one another, they enhance each other’s strengths, providing controlled motion that is precise, robust, and reliable.

Servo Gearboxes are robust! While there are high torque servos out there that doesn’t mean they are able to compare to the load capability of a Servo Gearbox. The small splined output shaft of a regular servo isn’t long enough, huge enough or supported sufficiently to handle some loads even though the torque numbers appear to be suitable for the application form. A servo gearbox isolates the load to the gearbox output shaft which is backed 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 on to the servo. Subsequently, the servo operates more freely and can transfer more torque to the result shaft of the gearbox.
