Servo gearheads provide mechanical advantage by multiplying electric motor torque while reducing the driven load’s reflected inertia back to the motor.
We supplies the widest range of gear technology providing optimal solutions significantly beyond the capabilities of various other gearhead suppliers.
Do you know why we still use today gearboxes while servo motors becoming stronger and more advanced? The gearboxes are found in many instances in combination with a servo motor, for example because they possess low backlash and are able to handle high torque. But still we didn’t give a servo gearhead remedy to the previous question: why! In this article 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 industrial applications, servo motors are used in which a drive-system has to be accurate or highly dynamic. The opinions to the engine is done through a resolver (analogue sensor of rotation) or encoder (digital sensor of rotation). A servo engine is managed by a servo amplifier, perhaps with a shaft controller.
The rotation frequency of the actuator is given back by the resolver or encoder. This is capable in addition to the rotational acceleration, also to look for the placement 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 haven’t any significant disadvantages more! So, why would you utilize a gearbox?
This has the next reasons:
If you want a suprisingly low rate, possibly in mixture with a higher 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 load determines the behaviour of the electric motor.
To be able to absorb the high radial or axial forces of the application form.
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, mount easily and directly onto AC brushless servo motors to supply industrial motion control equipment with torque multiplication and proper inertial matching. These gearheads are made for servo applications requiring precision, durability, and lengthy trouble-free operation.
