Mecvel Linear Actuators
A Linear actuator is a packaged unit that converts rotary motion into
linear movement and consists basically of an electric motor, gearbox and
leadscrew or ballscrew. As the screw is rotated by the motor /gearbox,
the nut extends and retracts the tube (or shaft) which is attached to
The speed of movement (mm) of this shaft and the acceptable load (N)
to be pushed (or pulled) is shown for each type of actuator on the speed/load
graphs. The actuator can be stopped at any time during its movement, however
consideration must be given to the rated maximum holding force. Duty cycle
should not be exceeded (unless an oversized actuator is used with higher
specification). Standard duty cycle is rated S3 30% (5mins cycle) @ 30oC
and temperature range is -10oC to + 60oC
The main features for Linear actuator selection are:
Load dynamics (thrust , pull and holding forces, inertia)
Generally actuators are non self locking, so additional devices have
to be fitted such as brakemotors. To control the actuator stroke there
are a number of options, simple magnetic reed switches, integrated mechanical
cam limit switches, resistive potentiometer and digital pulse encoder.
Other options for Mecvel Linear Actuators
Higher IP Ratings
There are other options available please ask for any special requirements.
All Mecvel actuators are manufactured to ISO 9001.
