Servo gearheads provide servo motor and gearbox 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 much beyond the capabilities of various other gearhead suppliers.
Do you know why we still use today gearboxes while servo motors becoming more powerful and more complex? The gearboxes are used in many instances in combination with a servo electric motor, for example because they possess low backlash and so are able to cope with high torque. But still we did not give an answer to the previous question: why! In this post 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 industrial applications, servo motors are used in which a drive-system has to be accurate or highly dynamic. The opinions to the electric motor is done through a resolver (analogue sensor of rotation) or encoder (digital sensor of rotation). A servo electric 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 direction of rotation. The servo amplifier compares the arranged rotational frequency with the measured rotational frequency. Right now the servo amplifier can drive the actuator to the desired values.
Interesting, AC Servo Motors have no significant disadvantages more! So, why would you utilize a gearbox?
This has the following reasons:
If you prefer a suprisingly low speed, possibly in combination with a higher torque.
If you want high torque. (Actuators with high torque can be found, but they are exponentially more expensive compared to the smaller servomotors)
Inertia matching, to be able to prevent that the strain determines the behaviour of the motor.
In order to absorb the high radial or axial forces of the application form.
If you would like to go “around the corner” otherwise the servomotor sticks out the application. Gearboxes are available in right-angled versions.
Baldor’s GBSM-series of low backlash, servo electric motor rated gearheads, install easily and directly onto AC brushless servo motors to supply industrial motion control devices with torque multiplication and proper inertial matching. These gearheads are made for servo applications needing precision, durability, and lengthy trouble-free operation.
