Servo gearheads provide mechanical benefit by multiplying engine torque while reducing the driven load’s reflected inertia back again to the motor.
We offers the widest range of gear technologies providing optimal solutions significantly servo gearhead beyond the capabilities of additional gearhead suppliers.
Are you aware why we still use today gearboxes while servo motors becoming stronger and more complex? The gearboxes are used in many instances in mixture with a servo engine, for instance because they have low backlash and are able to cope with high torque. But still we did not 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 motor follows the (complex) task given to him.
For commercial applications, servo motors are used where a drive-system needs to be accurate or highly dynamic. The feedback to the motor is done through a resolver (analogue sensor of rotation) or encoder (digital sensor of rotation). A servo electric motor is controlled by a servo amplifier, possibly with a shaft controller.
The rotation frequency of the actuator is given back by the resolver or encoder. This is capable in addition to the rotational velocity, also to look for the placement of the rotor and the path of rotation. The servo amplifier compares the established 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 next reasons:
If you want a very low speed, possibly in mixture with a higher torque.
If you want high torque. (Actuators with high torque are available, but they are exponentially more costly compared to the smaller servomotors)
Inertia matching, in order to prevent that the load determines the behaviour of the engine.
In order to absorb the high radial or axial forces of the application.
If you want 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 engine 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 designed for servo applications requiring precision, durability, and long trouble-free operation.
