Servo gearheads provide mechanical advantage by multiplying electric motor torque while servo gearhead reducing the driven load’s reflected inertia back again to the motor.
We offers the widest range of gear systems providing optimal solutions significantly beyond the features of additional gearhead suppliers.
Are you aware why we still use today gearboxes while servo motors becoming stronger and more complex? The gearboxes are used in many instances in mixture with a servo engine, for instance 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 article 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 engine follows the (complex) task given to him.
For commercial applications, servo motors are used in which a drive-system has to be accurate or highly powerful. The feedback to the electric motor 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. That is capable in addition to the rotational speed, also to look for the placement of the rotor and the direction of rotation. The servo amplifier compares the established 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 have no significant disadvantages more! Therefore, why would you utilize a gearbox?
This has the following reasons:
If you want a suprisingly low quickness, possibly in mixture with a higher torque.
If you need high torque. (Actuators with high torque are available, however they are exponentially more costly compared to the smaller servomotors)
Inertia matching, in order to prevent that the load determines the behaviour of the electric motor.
In order to absorb the high radial or axial forces of the application.
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 engine rated gearheads, attach 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 requiring precision, durability, and long trouble-free operation.
