Servo gearheads provide mechanical benefit by multiplying engine torque while reducing the driven load’s reflected inertia back to the motor.
We supplies the widest range of gear systems 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 situations in mixture with a servo engine, for instance 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 engine 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 electric motor is performed through a resolver (analogue sensor of rotation) or encoder (digital sensor of rotation). A servo engine is controlled by a servo amplifier, probably with a shaft controller.
The rotation frequency of the actuator is returned by the resolver or encoder. That is capable as well as the rotational speed, also to look for the position of the rotor and the path of rotation. The servo amplifier compares the set rotational frequency with the measured rotational frequency. Now 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 servo motor and gearbox reasons:
If you want a suprisingly low velocity, possibly in combination with an increased torque.
If you want high torque. (Actuators with high torque are available, however they are exponentially more costly compared to the smaller servomotors)
Inertia matching, to be able 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 want to go “around the corner” otherwise the servomotor sticks out the application. Gearboxes are available in right-angled versions.
Baldor’s GBSM-series of low backlash, servo engine rated gearheads, install easily and directly onto AC brushless servo motors to provide industrial motion control devices with torque multiplication and proper inertial matching. These gearheads are made for servo applications needing precision, durability, and lengthy trouble-free operation.
