Servo gearheads provide mechanical benefit by multiplying motor torque while reducing the driven load’s reflected inertia back to the motor.
We offers the widest range of gear technologies providing optimal solutions far beyond the features of various other gearhead suppliers.
Are you aware why we still make use of today gearboxes while servo motors becoming more powerful and more complex? The gearboxes are used in many cases in combination with a servo motor, for example because they possess low backlash and so 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 methods to follow or execute a command. A servo motor follows the (complex) job given to him.
For commercial applications, servo motors are used where a drive-system needs to be accurate or highly dynamic. The opinions to the motor is done through a resolver (analogue sensor of rotation) or encoder (digital sensor of rotation). A servo 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 in addition to the rotational speed, also to determine the placement of the rotor and the path of rotation. The servo amplifier compares the arranged rotational frequency with the measured rotational frequency. Now 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 following reasons:
If you prefer a suprisingly low quickness, possibly in combination with an increased torque.
If you need high torque. (Actuators with high torque can be found, but they are exponentially more expensive compared to the smaller servomotors)
Inertia matching, in order to prevent that the load servo motor and gearbox determines the behaviour of the engine.
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 can be found in right-angled versions.
Baldor’s GBSM-series of low backlash, servo electric motor rated gearheads, mount 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 long trouble-free operation.
