Servo gearheads provide mechanical advantage by multiplying electric motor torque while reducing the driven load’s reflected inertia back to the motor.
We supplies the widest range of gear systems 
providing optimal solutions far beyond the capabilities of additional gearhead suppliers.
Are you aware why we still make use of today servo gearhead Gearboxes while servo motors becoming stronger and more advanced? The gearboxes are used in many cases in combination with a servo electric motor, for instance because they possess low backlash and are able to handle high torque. But nonetheless we didn’t give an answer to the previous question: why! In this post 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) task given to him.
For industrial applications, servo motors are used where a drive-system needs to be accurate or highly dynamic. The opinions to the engine is performed through a resolver (analogue sensor of rotation) or encoder (digital sensor of rotation). A servo engine is controlled by a servo amplifier, perhaps with a shaft controller.
The rotation frequency of the actuator is returned by the resolver or encoder. That is capable in addition to the rotational rate, also to determine the position of the rotor and the direction of rotation. The servo amplifier compares the set 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 reasons:
If you prefer a suprisingly low speed, possibly in combination with a higher torque.
If you need high torque. (Actuators with high torque are available, however they are exponentially more expensive when compared to smaller servomotors)
Inertia matching, in order to prevent that the strain determines the behaviour of the electric motor.
To be able to absorb the high radial or axial forces of the application form.
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, mount easily and directly onto AC brushless servo motors to supply industrial motion control apparatus with torque multiplication and proper inertial matching. These gearheads are made for servo applications requiring precision, durability, and long trouble-free operation.
