Servo gearheads provide mechanical benefit by multiplying motor torque while reducing the driven load’s reflected inertia back to the motor.

We supplies the widest range of gear technology providing optimal solutions significantly beyond the features of other gearhead suppliers.
Have you any idea why we still make use of today gearboxes while servo motors becoming more powerful and more complex? The gearboxes are used in many cases in combination with a servo motor, for example because they possess low backlash and are able to deal with high torque. But servo gearhead nonetheless we did not give an answer to the previous query: why! In this article we discuss the operation of a servo drive and translate this through to the gearboxes.
Technically translated tis methods to follow or execute a command. A servo motor 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 powerful. The feedback to the engine is performed through a resolver (analogue sensor of rotation) or encoder (digital sensor of rotation). A servo electric motor is controlled by a servo amplifier, possibly with a shaft controller.

The rotation frequency of the actuator is returned by the resolver or encoder. This is capable in addition to the rotational quickness, also to look for the position of the rotor and the path of rotation. The servo amplifier compares the arranged rotational frequency with the measured rotational frequency. Today the servo amplifier can drive the actuator to the desired values.
Interesting, AC Servo Motors have no significant disadvantages more! So, why would you utilize a gearbox?
This has the following reasons:

If you prefer a very low swiftness, possibly in mixture with a higher torque.
If you need high torque. (Actuators with high torque can be found, but they are exponentially more costly compared to the smaller servomotors)
Inertia matching, to be able to prevent that the strain determines the behaviour of the engine.
To be able to absorb the high radial or axial forces of the application.
If you want to go “around the corner” otherwise the servomotor sticks out the application. Gearboxes can be found in right-angled versions.
Baldor’s GBSM-series of low backlash, servo motor rated gearheads, attach easily and directly onto AC brushless servo motors to supply industrial motion control products with torque multiplication and proper inertial matching. These gearheads are made for servo applications needing precision, durability, and long trouble-free operation.
