Ball Screw Servo Motor Actuator.
Integrated Ball Screws are available in the following
25mm, 32mm and 40mm with leads of 2.5mm to 25mm.
It can generate forces from 500lbs up to 8000lbs. It can travel at
speeds up to
2000mm per second.
This product can be used in place of pneumatic and hydraulic
This product can be configured as a linear actuator in place of a Ball
Slide or Belt Driven Slide / actuator.
as a Cylinder
As an electric cylinder it does not require an
air supply or hydraulic
power pack. The Servo Motor Actuator is useful in
applications when air,
hydraulic fluid or noise is not desired. The Servo Motor
provides Fast, Accurate and Repeatable positioning which is difficult
when using cylinders. Two Servo Motor Actuators can be
synchronized together to lift or push simultaneously.
as an Actuator
Brief Overview of Typical Ball Screw Actuators
and main benefits of the
Linear Servo Motor Actuator is as follows:
typical Ball screw applications you fix the ball nut and spin the screw.
1. The main disadvantage of a
long ball screw is that the slide cannot move at high speeds due to the
oscillations or whip.
2. This situation causes
vibration and can also bend the ball screw.
3. In order to move at higher
speeds you must use a ball nut with a high lead in order to reduce the
the screw. This in turn reduces the available force.
The Linear Ball Screw Servo Motor Actuator provides
High Force and High
Speeds with Ball screw Precision, Accuracy and Repeatability.
1. The main benefit is due
to the ball screw being fixed at both ends while the Ball Nut rotates.
2. The secondary benefit is
that coupling are not required which increase
Additional benefits: Integrated into the frame of the
machine, self contained small footprint compared to other
Available in custom lengths up to 3 Meters /118 inches / 9.84
Ball Screw Servo Motor Actuator provides the High
Speeds of a belt
drive with the high forces, Precision, Accuracy and Repeatability of a
as a Dual Carriage Actuator
Due to the Ball Screw being fixed, a Unique
operational advantage can
be obtained. Several Linear Servo Motors can operate either
or synchronized as they share the same Ball Screw.
Two Linear Servo motors are used in the Y axis of a CNC Gantry
machinery with the following benefits:
-Increased production, double production parts, two independent
motions on a single work piece with independent tool
Information / theory of operation
The Linear Ball Screw Servo Motor
Actuator is a
brushless servo motor with a
hollow shaft design to accommodate ball nuts and a ball screws
standard DIN69051. The Linear Ball Screw Servo Motor
servoactuator converts the rotation of the motor into a linear movement
ball nut with ball screw assembly. The ball nut is attached to
of the servo motor and rotates with it. The ball
passes through the rotor and remains stationary, as it is fixed at both
linear bearing with guide or rail assembly is also required to support
guide the servoactuator and load.
The linear servoactuator does not include the ball nut or the
The Ball screw and ball nut can be purchased as an option
servoactuator. When choosing the ball nut please pay attention to
static load ratings.
The linear servoactuator does not include the linear bearing
with guide or
rail assembly. The linear bearing with guide or rail assembly
purchased as an option with the servo actuator.
