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

We offers the widest range of gear systems providing optimal solutions far beyond the features of other gearhead suppliers.
Are you aware why we still use today gearboxes while servo motors becoming more powerful and more advanced? The gearboxes are used in many instances in combination with a servo engine, for example because they possess low backlash and so are able to cope with high torque. But still we didn’t give an answer to the previous question: why! In this post we discuss the procedure of a servo drive and translate this through to the gearboxes.
Technically translated tis means 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 highly dynamic. The opinions to the motor is done through a resolver (analogue sensor of rotation) or encoder (digital sensor of rotation). A servo motor is controlled by a servo amplifier, perhaps with a shaft controller.

The servo gearhead rotation frequency of the actuator is returned by the resolver or encoder. This is capable in addition to the rotational acceleration, also to look for the placement of the rotor and the path of rotation. The servo amplifier compares the established rotational frequency with the measured rotational frequency. Right now the servo amplifier can drive the actuator to the desired values.
Interesting, AC Servo Motors haven’t any significant disadvantages more! So, why would you utilize a gearbox?
This has the next reasons:

If you want a very low speed, 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 when compared to smaller servomotors)
Inertia matching, to be able to prevent that the strain determines the behaviour of the motor.
In order to absorb the high radial or axial forces of the application form.
If you would like to go “nearby” otherwise the servomotor sticks out 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 provide industrial motion control products with torque multiplication and proper inertial matching. These gearheads are made for servo applications needing precision, durability, and lengthy trouble-free operation.
