Servo gearheads provide mechanical benefit by multiplying electric motor torque while reducing the driven load’s reflected inertia back again to the motor.
We supplies the widest range of gear technologies providing optimal solutions far beyond the features of other gearhead suppliers.
Do you know why we still make use of today gearboxes while servo motors becoming stronger and more advanced? The gearboxes are found in many situations in mixture with a servo engine, for instance because they have low backlash and so are able to servo gearhead handle high torque. But nonetheless we didn’t give a remedy to the previous issue: 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 motor follows the (complex) task given to him.
For commercial applications, servo motors are used where a drive-system has to be accurate or highly dynamic. The opinions to the engine is performed through a resolver (analogue sensor of rotation) or encoder (digital sensor of rotation). A servo engine is managed by a servo amplifier, probably 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 determine the position of the rotor and the direction of rotation. The servo amplifier compares the established rotational frequency with the measured rotational frequency. Right now 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 following reasons:
If you want a very low rate, possibly in mixture with a higher torque.
If you need 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 motor.
To be able to absorb the high radial or axial forces of the application form.
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 electric motor rated gearheads, mount easily and directly onto AC brushless servo motors to supply 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.
