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

We supplies the widest selection of gear technologies providing optimal servo gearhead solutions considerably beyond the features of various other gearhead suppliers.
Are you aware why we still make use of 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 instance because they have low backlash and are able to handle high torque. But still we did not give a remedy to the previous issue: why! In this post we discuss the operation of a servo drive and translate this to the gearboxes.
Technically translated tis means 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 needs to be accurate or highly powerful. The feedback to the engine is done through a resolver (analogue sensor of rotation) or encoder (digital sensor of rotation). A servo electric 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 in addition to the rotational acceleration, also to look for the placement 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 required values.
Interesting, AC Servo Motors have no significant disadvantages more! So, why would you use a gearbox?
This has the next reasons:

If you prefer a suprisingly low velocity, possibly in mixture with a higher torque.
If you need high torque. (Actuators with high torque are available, but they are exponentially more costly when compared to smaller servomotors)
Inertia matching, in order to prevent that the load determines the behaviour of the engine.
To be able to absorb the high radial or axial forces of the application.
If you want to go “around the corner” otherwise the servomotor shines 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 apparatus with torque multiplication and proper inertial matching. These gearheads are made for servo applications needing precision, durability, and lengthy trouble-free operation.
