Servo gearheads provide mechanical benefit by multiplying motor torque while reducing the driven load’s reflected inertia back to the motor.
We supplies the widest selection of gear systems providing optimal solutions far beyond the capabilities of various other gearhead suppliers.
Do you know why we still use today gearboxes while servo motors becoming stronger and more complex? The gearboxes are found in many instances in mixture with a servo motor, for example because they possess low backlash and are able to cope with high torque. But nonetheless we did not give an answer 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 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 opinions to the electric motor 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, possibly 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 speed, also to determine the placement of the rotor and the path of rotation. The servo amplifier servo motor and gearbox compares the set rotational frequency with the measured rotational frequency. Now the servo amplifier can drive the actuator to the desired values.
Interesting, AC Servo Motors haven’t any significant disadvantages more! Therefore, why would you use a gearbox?
This has the next reasons:
If you want a suprisingly low velocity, possibly in mixture with a higher torque.
If you want high torque. (Actuators with high torque are available, however they are exponentially more costly when compared to smaller servomotors)
Inertia matching, in order to prevent that the strain determines the behaviour of the motor.
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 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 made for servo applications needing precision, durability, and long trouble-free operation.
