Servo gearheads provide mechanical advantage by multiplying motor torque while reducing the driven load’s reflected servo motor and gearbox inertia back to the motor.
We offers the widest range of gear systems providing optimal solutions considerably beyond the features of other gearhead suppliers.
Have you any idea why we still use today gearboxes while servo motors becoming more powerful and more advanced? The gearboxes are found in many situations in 
combination with a servo engine, for example because they possess low backlash and so are able to cope with high torque. But nonetheless we didn’t give an answer to the previous question: why! In this article we discuss the operation of a servo drive and translate this to the gearboxes.
Technically translated tis means to follow or execute a command. A servo engine follows the (complex) job given to him.
For industrial applications, servo motors are used in which a drive-system needs to be accurate or highly dynamic. The opinions to the motor is done through a resolver (analogue sensor of rotation) or encoder (digital sensor of rotation). A servo electric motor is managed by a servo amplifier, probably with a shaft controller.
The rotation frequency of the actuator is given back by the resolver or encoder. That is capable as well as the rotational speed, also to look for the position of the rotor and the path of rotation. The servo amplifier compares the set rotational frequency with the measured rotational frequency. Right now the servo amplifier can drive the actuator to the required values.
Interesting, AC Servo Motors have no significant disadvantages more! So, why would you use a gearbox?
This has the next reasons:
If you prefer a very low acceleration, possibly in combination with a higher torque.
If you want high torque. (Actuators with high torque can be found, but they are exponentially more costly when compared to smaller servomotors)
Inertia matching, in order to prevent that the load determines the behaviour of the electric motor.
In order to absorb the high radial or axial forces of the application form.
If you would like to go “around the corner” otherwise the servomotor sticks out the application. Gearboxes are available in right-angled versions.
Baldor’s GBSM-series of low backlash, servo electric motor rated gearheads, attach easily and directly onto AC brushless servo motors to supply industrial motion control devices with torque multiplication and proper inertial matching. These gearheads are made for servo applications requiring precision, durability, and lengthy trouble-free operation.
