As servo technology has evolved-with manufacturers creating smaller, yet better motors -gearheads are becoming increasingly essential partners in motion control. Locating the optimum pairing must consider many engineering considerations.
• A servo motor operating at low rpm operates inefficiently. Eddy currents are loops of electric current that are induced within the motor during procedure. The eddy currents in fact produce a drag pressure within the electric motor and will have a greater negative impact on motor performance at lower rpms.
• An off-the-shelf motor’s parameters may not be ideally suitable for run at a minimal rpm. When a credit card applicatoin runs the aforementioned engine at 50 rpm, essentially it isn’t using most of its available rpm. Because the voltage constant (V/Krpm) of the electric motor is set for a higher rpm, the torque continuous (Nm/amp)-which can be directly related to it-is certainly lower than it needs to be. Consequently, the application requirements more current to drive it than if the application had a motor particularly made for 50 rpm. A gearhead’s ratio reduces the motor 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 permit 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 levels of rotation. Most of the Servo Gearboxes utilize a patented external potentiometer to ensure that the rotation amount is independent of 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 result shaft) into the placement that the signal from the servo controller demands.
Machine designers are increasingly turning to gearheads to take benefit of the latest advances in servo electric motor technology. Essentially, a gearhead converts high-velocity, low-torque energy into low-speed, high-torque output. A servo engine provides extremely accurate positioning of its output shaft. When both of these products are paired with each other, they promote each other’s strengths, offering controlled motion that’s precise, robust, and reliable.

Servo Gearboxes are robust! While there are high torque servos available that doesn’t indicate they can compare to the load capacity of a Servo Gearbox. The tiny splined result shaft of a normal servo isn’t lengthy enough, large enough or supported well enough to handle some loads despite the fact that the torque numbers look like suitable for the application form. A servo gearbox isolates the strain to the gearbox output shaft which is supported by a pair of ABEC-5 precision ball bearings. The exterior shaft can withstand intense loads in the axial and radial directions without transferring those forces on to the servo. In turn, the servo operates more freely and can transfer more torque to the output shaft of the gearbox.
