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

We supplies the widest range of gear technology providing optimal solutions far beyond the features of various other gearhead suppliers.
Have you any idea why we still make use of today gearboxes while servo motors becoming more powerful and more advanced? The gearboxes are found in many cases in combination with a servo motor, for instance because they have low backlash and are able to cope with high torque. But nonetheless we didn’t give an answer to the previous issue: why! In this article 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 where a drive-system needs to be accurate or highly dynamic. 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 managed by a servo amplifier, perhaps with a shaft controller.

The rotation frequency of the actuator is returned by the resolver or encoder. This is capable in addition to the rotational speed, also to determine the position of the rotor and the path of rotation. The servo amplifier compares the set 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! So, why would you use a gearbox?
This has the following reasons:

If you prefer a very low quickness, possibly in mixture with an increased torque.
If you need high torque. (Actuators with high torque are available, however they are exponentially more expensive compared to the smaller servomotors)
Inertia matching, to be able to prevent that the load determines the behaviour of the electric motor.
In order to absorb the high radial or axial forces of the application form.
If you want to go “nearby” otherwise the servomotor shines the application. Gearboxes can be found in right-angled versions.
Baldor’s GBSM-series of low backlash, servo motor rated gearheads, install easily and directly onto AC brushless servo motors to provide industrial motion control apparatus with torque multiplication and proper inertial matching. These gearheads are designed for servo applications requiring precision, durability, and long trouble-free operation.
