Servo gearheads provide mechanical advantage by multiplying electric motor torque while reducing the driven load’s reflected inertia back to the motor.
We offers the widest selection of gear systems providing optimal solutions significantly beyond the capabilities of various other gearhead suppliers.
Have you any idea why we still make use of today servo gearhead gearboxes while servo motors becoming stronger and more complex? The gearboxes are found in many situations in mixture with a servo motor, for example because they have 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 through to the gearboxes.
Technically translated tis means to follow or execute a command. A servo engine follows the (complex) task given to him.
For industrial applications, servo motors are used in which a drive-system needs 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 motor is managed by a servo amplifier, perhaps 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 acceleration, also to determine the position of the rotor and the path of rotation. The servo amplifier compares the arranged rotational frequency with the measured rotational frequency. Today the servo amplifier can drive the actuator to the required values.
Interesting, AC Servo Motors have no significant disadvantages more! Therefore, why would you use a gearbox?
This has the following reasons:
If you want a very low acceleration, possibly in mixture with a higher torque.
If you want high torque. (Actuators with high torque can be found, but they are exponentially more costly when compared to 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 form.
If you want to go “nearby” 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, attach easily and directly onto AC brushless servo motors to supply industrial motion control gear with torque multiplication and proper inertial matching. These gearheads are made for servo applications needing precision, durability, and long trouble-free operation.
