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

We supplies the widest selection of gear technologies providing optimal solutions much beyond the capabilities of additional gearhead suppliers.
Have you any idea why we still use today gearboxes while servo motors becoming stronger and more servo gearhead complex? The gearboxes are used in many instances in combination with a servo motor, for instance because they have low backlash and are able to handle high torque. But still we didn’t give a remedy to the previous issue: why! In this article we discuss the procedure of a servo drive and translate this to the gearboxes.
Technically translated tis methods to follow or execute a command. A servo motor follows the (complex) task given to him.

For commercial applications, servo motors are used in which a drive-system has to be accurate or highly powerful. The feedback to the engine is done through a resolver (analogue sensor of rotation) or encoder (digital sensor of rotation). A servo engine is managed by a servo amplifier, probably 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 speed, also to determine the placement of the rotor and the path of rotation. The servo amplifier compares the arranged rotational frequency with the measured rotational frequency. Now the servo amplifier can drive the actuator to the desired 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 suprisingly low quickness, possibly in combination with an increased torque.
If you want high torque. (Actuators with high torque can be found, but they are exponentially more costly compared to the smaller servomotors)
Inertia matching, in order 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 would like to go “around the corner” otherwise the servomotor shines the application. Gearboxes can be found in right-angled versions.
Baldor’s GBSM-series of low backlash, servo engine rated gearheads, install 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 requiring precision, durability, and long trouble-free operation.
