servo motor and gearbox

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

We supplies the widest range of gear systems providing servo motor and gearbox optimal solutions far beyond the capabilities 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 complex? The gearboxes are found in many cases in mixture with a servo electric motor, for example because they have low backlash and so are able to deal with high torque. But still we didn’t give an answer to the previous issue: why! In this article 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 electric motor follows the (complex) job given to him.

For industrial applications, servo motors are used where a drive-system needs to be accurate or highly powerful. The opinions 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, possibly with a shaft controller.

The rotation frequency of the actuator is given back by the resolver or encoder. That is capable as well as the rotational velocity, also to determine the position of the rotor and the path of rotation. The servo amplifier compares the arranged 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 utilize a gearbox?
This has the next reasons:

If you want a suprisingly low speed, possibly in mixture with an increased torque.
If you want high torque. (Actuators with high torque can be found, however they are exponentially more expensive when compared to 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.
If you would like 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 electric motor rated gearheads, attach easily and directly onto AC brushless servo motors to provide industrial motion control gear with torque multiplication and proper inertial matching. These gearheads are designed for servo applications requiring precision, durability, and long trouble-free operation.
