As servo technology has evolved-with manufacturers making smaller, yet more powerful motors -gearheads are becoming increasingly essential companions in motion control. Finding the optimal 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 engine during operation. The eddy currents in fact produce a drag drive within 
the electric motor and will have a greater negative effect on motor performance at lower rpms.
• An off-the-shelf motor’s parameters might not be ideally suited to run at a low rpm. When an application 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 an increased rpm, the torque constant (Nm/amp)-which is usually directly linked to it-is lower than it needs to be. Consequently, the application needs more current to operate a vehicle it than if the application form had a motor particularly made for 50 rpm. A gearhead’s ratio reduces the electric motor rpm, which explains why gearheads are occasionally called gear reducers. Utilizing a gearhead with a 40:1 ratio,
the 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 just how much rotation is achieved from a servo. Most hobby servos are limited by just beyond 180 degrees of rotation. Most of the Servo Gearboxes make use of a patented external potentiometer so that the rotation amount is in addition to the equipment ratio set up 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 placement that the signal from the servo controller demands.
Machine designers are increasingly embracing gearheads to take benefit of the most recent advances in servo motor technology. Essentially, a gearhead converts high-swiftness, low-torque energy into low-speed, high-torque output. A servo electric motor provides extremely accurate positioning of its result shaft. When these two gadgets are paired with each other, they promote each other’s strengths, providing controlled motion that’s precise, robust, and dependable.
Servo Gearboxes are robust! While there are high torque servos out there that doesn’t mean they are able to compare to the strain capacity of a Servo Gearbox. The tiny splined output shaft of a normal servo isn’t lengthy enough, large enough or supported sufficiently to handle some loads even though the torque numbers look like appropriate for the application form. A servo gearbox isolates the load to the gearbox result shaft which is supported by a pair of ABEC-5 precision ball bearings. The exterior shaft can withstand severe loads in the axial and radial directions without transferring those forces on to the servo. Subsequently, the servo runs more freely and can transfer more torque to the output shaft of the gearbox.
The opportunities are limitless with servo motor gearbox!
