Servo gearheads provide mechanical advantage 
by multiplying electric motor torque while reducing the driven load’s reflected inertia back again to the motor.
We offers the widest range of gear technology providing optimal solutions significantly beyond the features of various other gearhead suppliers.
Have you any idea why we still use today gearboxes while servo motors becoming stronger and more advanced? The gearboxes are used in many situations in combination with a servo engine, for example because they possess low backlash and so are able to deal with high torque. But still we didn’t give a remedy 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 methods to follow or execute a command. A servo electric motor follows the (complex) job given to him.
For commercial applications, servo motors are used where a drive-system needs to be accurate or highly powerful. The feedback to the motor is done through a resolver (analogue sensor of rotation) or encoder (digital sensor of rotation). A servo electric motor is controlled by a servo amplifier, possibly with a shaft controller.
The rotation frequency of the actuator is returned by the resolver or encoder. This is capable as well as the rotational velocity, also to look for the position 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 desired values.
Interesting, AC Servo Motors haven’t any significant disadvantages more! So, why would you utilize a gearbox?
This has the following reasons:
If you prefer a very low rate, possibly in combination with a higher torque.
If you need high torque. (Actuators with high torque are available, but they are exponentially more expensive when compared to smaller servomotors)
Inertia matching, in order to prevent that the load servo gearhead determines the behaviour of the engine.
In order to absorb the high radial or axial forces of the application.
If you want to go “nearby” otherwise the servomotor sticks out the application. Gearboxes can be found 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 devices with torque multiplication and proper inertial matching. These gearheads are designed for servo applications requiring precision, durability, and lengthy trouble-free operation.
