Servo gearheads provide mechanical benefit by multiplying motor torque while reducing the driven load’s reflected inertia back again to the motor.
We supplies the widest range of gear technology providing optimal solutions significantly beyond the capabilities of other gearhead suppliers.
Do you know why we still make use of today gearboxes while servo motors becoming stronger and more complex? The gearboxes are found in many cases in mixture with a servo electric motor, for example because they possess low backlash and are able to deal with high torque. But still we didn’t 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 methods to follow or execute a command. A servo motor follows the (complex) job given to him.
For industrial applications, servo motors are used in which a drive-system needs 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 engine is controlled by a servo amplifier, perhaps with a shaft controller.
The rotation servo motor and gearbox frequency of the actuator is returned 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. At this point 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 prefer a very low swiftness, possibly in combination with a higher torque.
If you need high torque. (Actuators with high torque can be found, but they are exponentially more costly compared to the 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 “nearby” otherwise the servomotor shines 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 supply industrial motion control apparatus with torque multiplication and proper inertial matching. These gearheads are created for servo applications needing precision, durability, and lengthy trouble-free operation.
