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

We supplies the widest selection of gear systems providing optimal solutions significantly beyond the capabilities of various other gearhead suppliers.
Are you aware why we still make use of today gearboxes while servo motors becoming more powerful and more complex? The gearboxes are found in many instances in mixture with a servo motor, for instance because they have low backlash and so are able to handle high torque. But nonetheless we didn’t give an answer to the previous issue: why! In this article we discuss the operation 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) job given to him.

For industrial applications, servo motors are used where a drive-system has to be accurate or servo gearhead highly powerful. 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, perhaps 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 velocity, also to look for the placement of the rotor and the path of rotation. The servo amplifier compares the arranged rotational frequency with the measured rotational frequency. At this point 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 following reasons:

If you want a very low swiftness, possibly in combination with an increased torque.
If you need high torque. (Actuators with high torque can be found, however they are exponentially more costly when compared to smaller servomotors)
Inertia matching, in order to prevent that the strain determines the behaviour of the electric motor.
In order to absorb the high radial or axial forces of the application form.
If you want 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 provide industrial motion control equipment with torque multiplication and proper inertial matching. These gearheads are designed for servo applications needing precision, durability, and long trouble-free operation.
