Servo gearheads provide mechanical benefit 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 considerably beyond the features of additional gearhead suppliers.
Are you aware why we still use today gearboxes while servo motors becoming more powerful and more complex? The gearboxes are used in many cases in mixture with a servo motor, for example because they possess low backlash and are able to cope with high torque. But still we did not give a remedy 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 motor 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 motor is done through a resolver (analogue sensor of rotation) or servo gearhead encoder (digital sensor of rotation). A servo motor is controlled by a servo amplifier, probably with a shaft controller.

The rotation frequency of the actuator is given back by the resolver or encoder. This is capable as well as the rotational speed, also to look for the placement of the rotor and the direction of rotation. The servo amplifier compares the arranged 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! Therefore, why would you utilize a gearbox?
This has the next reasons:

If you want a suprisingly low velocity, possibly in mixture with a higher torque.
If you want high torque. (Actuators with high torque can be found, but they are exponentially more expensive compared to the smaller servomotors)
Inertia matching, to be able 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 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, mount easily and directly onto AC brushless servo motors to supply industrial motion control tools with torque multiplication and proper inertial matching. These gearheads are made for servo applications needing precision, durability, and long trouble-free operation.
