Servo gearheads provide mechanical advantage by multiplying engine torque while reducing the driven load’s reflected inertia back to the motor.
We supplies the widest selection of gear technology providing optimal solutions considerably beyond the capabilities of additional gearhead suppliers.
Have you any idea why we still use today gearboxes while servo motors becoming more powerful and more complex? The gearboxes are used in many situations in mixture with a servo motor, for example because they possess low backlash and so are able to handle high torque. But still we didn’t give an answer to the previous query: why! In this post we discuss the procedure 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) task given to him.
For industrial applications, servo motors are used where a drive-system has 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 electric motor is managed by a servo amplifier, probably with a shaft controller.
The rotation frequency of the actuator is returned by the resolver or encoder. This is capable as well as the rotational velocity, also to look for the position of the rotor and the direction 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 required values.
Interesting, AC Servo Motors haven’t any significant disadvantages more! Therefore, why would you utilize a gearbox?
This has the next reasons:
If you want a very low rate, possibly in combination with an increased torque.
If you need high torque. (Actuators with high torque are available, however they are exponentially more costly when compared to smaller servomotors)
Inertia matching, in order to prevent that the load determines the behaviour of the engine.
To be able to absorb the high radial or axial forces of the application form.
If you want to go “around the corner” otherwise the servomotor shines the application. Gearboxes can be found in right-angled versions.
Baldor’s GBSM-series of low backlash, servo motor rated gearheads, attach easily and directly onto AC brushless servo motors to supply industrial motion control servo motor and gearbox apparatus with torque multiplication and proper inertial matching. These gearheads are made for servo applications requiring precision, durability, and long trouble-free operation.
