Servo gearheads provide mechanical advantage by multiplying motor torque while reducing the driven load’s reflected servo gearhead inertia back to the motor.
We supplies the widest range of gear technology providing optimal solutions much 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 found in many situations in mixture with a servo motor, for example because they possess low backlash and so are able to handle high torque. But still we did not give an answer 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 means to follow or execute a command. A servo motor follows the (complex) task given to him.
For commercial applications, servo motors are used in which a drive-system has 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 motor is controlled by a servo amplifier, probably with a shaft controller.
The rotation frequency of the actuator is returned by the resolver or encoder. That is capable in addition to the rotational quickness, also to determine the position 
of the rotor and the direction 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 have no significant disadvantages more! So, why would you use a gearbox?
This has the next reasons:
If you prefer a very low speed, possibly in combination with an increased torque.
If you want 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 engine.
To be able to absorb the high radial or axial forces of the application.
If you want to go “nearby” otherwise the servomotor shines 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 provide industrial motion control tools with torque multiplication and proper inertial matching. These gearheads are made for servo applications needing precision, durability, and lengthy trouble-free operation.
