Servo gearheads provide mechanical advantage by multiplying motor torque while reducing the driven load’s reflected inertia back again to the motor.
We offers the widest selection of gear technology providing optimal solutions considerably beyond the features of other gearhead suppliers.
Have you any idea why we still use 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 have low backlash and so are able to handle high torque. But nonetheless we did not give a remedy to the previous query: why! In this article 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 engine follows the (complex) job given to him.
For commercial applications, servo motors are used where a drive-system has to be accurate or highly powerful. The opinions to the engine is performed through a resolver (analogue sensor of rotation) or encoder (digital sensor of rotation). A servo motor is controlled by a servo amplifier, possibly with a shaft controller.
The rotation frequency of the actuator is returned by the resolver or encoder. That is capable in addition to the rotational speed, also to determine the position of the rotor and the direction of rotation. The servo amplifier compares the set rotational frequency with the measured rotational frequency. Right now the servo amplifier can drive the actuator to the desired values.
Interesting, AC Servo Motors haven’t any significant disadvantages more! So, why would you utilize a gearbox?
This has the next reasons:
If you want a very low speed, possibly in combination with a higher torque.
If you want high torque. (Actuators with high torque are available, but they are exponentially more expensive servo gearhead compared to the smaller servomotors)
Inertia matching, in order to prevent that the strain determines the behaviour of the motor.
To be able 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 can be found in right-angled versions.
Baldor’s GBSM-series of low backlash, servo electric motor rated gearheads, install 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 requiring precision, durability, and lengthy trouble-free operation.
