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

We offers the widest selection of gear technologies providing optimal solutions significantly beyond the capabilities of various other gearhead suppliers.
Do you know why we still make use of today gearboxes while servo motors becoming stronger 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 nonetheless we did not give an answer to the previous query: 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 electric motor follows the (complex) job given to him.

For commercial 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 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. That is capable in addition to the rotational velocity, also to determine the placement of the rotor and the path of rotation. The servo amplifier compares the established rotational frequency with the measured rotational frequency. Today the servo amplifier can drive the actuator to the required values.
Interesting, AC Servo Motors haven’t any significant disadvantages more! Therefore, why would you use a gearbox?
This has the following reasons:

If you want a very low swiftness, possibly in mixture with a higher torque.
If you want high torque. (Actuators with high torque can be found, however they are exponentially more expensive compared to the 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 servo gearhead application form.
If you want to go “around the corner” otherwise the servomotor sticks out the application. Gearboxes can be found in right-angled versions.
Baldor’s GBSM-series of low backlash, servo motor rated gearheads, mount easily and directly onto AC brushless servo motors to provide industrial motion control products with torque multiplication and proper inertial matching. These gearheads are designed for servo applications requiring precision, durability, and lengthy trouble-free operation.
