Servo gearheads provide mechanical benefit by multiplying engine torque while reducing the driven load’s reflected inertia back again to the motor.

We supplies the widest selection of gear technologies providing optimal solutions significantly beyond the capabilities of additional gearhead suppliers.
Do you know why we still use today gearboxes while servo motors becoming more powerful and more advanced? The gearboxes are found in many instances in mixture with a servo engine, for example because they possess low backlash and so are able to deal with high torque. But nonetheless we did not give an answer to the previous issue: why! In this post we discuss the procedure of a servo drive and translate this through to the gearboxes.
Technically translated tis methods to follow or execute a command. A servo engine follows the (complex) task 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 engine is performed through a resolver (analogue sensor of rotation) or encoder (digital sensor of rotation). A servo electric motor is managed by a servo amplifier, possibly with a shaft controller.

The rotation frequency of the actuator is given back by the resolver or encoder. That is capable as well as the rotational swiftness, also to look for the placement of the rotor and the direction of rotation. The servo amplifier compares the set 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 haven’t any significant disadvantages more! Therefore, why would you use a gearbox?
This has the next reasons:

If you want a very low acceleration, possibly in mixture with a higher torque.
If you need high torque. (Actuators with high torque can be found, but they are exponentially more costly compared to the smaller servomotors)
Inertia matching, to be able to prevent that the strain determines the behaviour of the electric motor.
In order to absorb the high radial or axial forces of the application form.
If you would like to go “nearby” otherwise the servomotor shines the application. Gearboxes are available in right-angled versions.
Baldor’s GBSM-series of low backlash, servo electric motor rated gearheads, attach easily and servo motor and gearbox directly onto AC brushless servo motors to supply industrial motion control tools with torque multiplication and proper inertial matching. These gearheads are designed for servo applications requiring precision, durability, and lengthy trouble-free operation.
