Servo gearheads provide mechanical benefit by multiplying electric motor torque while reducing the driven load’s reflected inertia back to the motor.
We offers the widest selection of gear technologies providing optimal solutions much servo gearhead beyond the features of additional gearhead suppliers.
Are you aware why we still use today gearboxes while servo motors becoming stronger and more advanced? The gearboxes are used in many instances in combination with a servo electric motor, for example because they possess low backlash and are able to cope with high torque. But nonetheless we didn’t give a remedy to the previous question: 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 electric 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 powerful. The opinions to the engine 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 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. 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 next reasons:
If you want a suprisingly low rate, possibly in combination 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 strain determines the behaviour of the electric motor.
To be able to absorb the high radial or axial forces of the application form.
If you want to go “around the corner” otherwise the servomotor shines the application. Gearboxes are available in right-angled versions.
Baldor’s GBSM-series of low backlash, servo engine rated gearheads, mount 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 needing precision, durability, and lengthy trouble-free operation.
