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

We offers the widest selection of gear technologies providing optimal solutions far beyond the capabilities of other gearhead suppliers.
Do you know why we still use today gearboxes while servo motors becoming more powerful and more advanced? The gearboxes are found in many instances in combination with a servo motor, for example because they have low backlash and are able to cope with high torque. But nonetheless we did not give an answer to the previous issue: why! In this post 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 engine follows the (complex) job given to him.

For industrial applications, servo motors are used in which a drive-system has to be accurate or highly dynamic. The feedback to the electric motor is performed through a resolver (analogue sensor of rotation) or encoder (digital sensor of rotation). A servo electric motor is managed by a servo amplifier, possibly with a shaft controller.

The rotation frequency of the actuator is given back by the resolver or encoder. This is capable in addition to the rotational acceleration, 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 haven’t any significant disadvantages more! Therefore, why would you utilize a gearbox?
This has the following servo motor and gearbox reasons:

If you want a very low swiftness, possibly in mixture with an increased torque.
If you need high torque. (Actuators with high torque can be found, however they are exponentially more expensive when compared to smaller servomotors)
Inertia matching, in order to prevent that the load determines the behaviour of the motor.
In order to absorb the high radial or axial forces of the application.
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 engine rated gearheads, attach easily and directly onto AC brushless servo motors to supply industrial motion control gear with torque multiplication and proper inertial matching. These gearheads are created for servo applications needing precision, durability, and long trouble-free operation.
