They can be configured as motor-only, open-loop variants or supplied complete with the USA-based motion control specialist’s StepSERVO integrated motors as all-in-one programmable closed-loop linear motion positioning solutions with optional network communication.
Available from Mclennan, AMP’s European distribution partner, these very compact linear actuators have leadscrew or rolled ball screw mechanics or, where improved backlash is required, a patented Constant Force lead screw option, featuring a self-adjusting polymer nut arrangement.
A comprehensive choice of options, covering motor and motion control systems, fitted brakes and encoders, precision grades and working strokes, make the MLA series extremely customisable.
AMP’s MLA and MEA series linear positioning actuators
The four MLA actuator models cover stroke lengths from 10mm up to 300mm, in both leadscrew and ball screw driven variants. Through the range, the choice of leadscrew and ballscrew pitches offered allow the user to select the best combination for speed vs resolution with maximum rates up to 100mm/sec achievable for the largest size.
The smallest MLA20 actuator with its NEMA 11 frame motor has a width of 22 mm and a height over the carriage of just under 25mm.
The largest MLA42 model, based on the NEMA23 frame stepper, has a width of 62mm and a height over the carriage of 35.5mm.
The maximum load capacity for this model is based on the lead screw/ball screw pitch, with a maximum of 7kg horizontal and 4.4kg vertical.
The StepSERVO versions of the MLA actuator range are available on the three larger models. This closed-loop stepper technology, with its integrated motor drive, programmed control and optional networking, provides a decentralised solution for positioning systems.
Benefits include reduced machine installation cost through minimised machine wiring, faster machine build and design time, and an Industry 4.0-attuned control concept.
These ‘smart’ actuators are available with a wide choice of control options, including step/direction, +/- 10V DC for torque/velocity and positioning.
AMP’s Q programming software takes care of streaming commands, and includes maths and machine I/O control functions.
Options for StepSERVO include RS232 or RS485, Modbus RTU and CANopen communications, as well as EtherNet/IP and Power over Ethernet (PoE). StepSERVO technology is, of course, also available in a wide range of separate integrated motors with all of these options in NEMA 11 to 34 frame sizes.
Complete specifications for each MLA series actuator size, covering the many options, load capability and dimensioned drawings are included in a PDF format catalogue, available on request from Mclennan.
Also available from AMP, and fully supported by Mclennan, are MEA series linear actuators, which integrate a through-screw motor with a high-precision ball guide for maximum space saving.
Mclennan represents AMP, along with other motion component and systems manufacturers providing motion and automation control solutions.
With its own in-house design and build capability, Mclennan supplies machine builders and OEMs motion solutions from single components to complete systems – including stepper, brushed and brushless servo motors, integrated motors, and many other motor types, along with drives, gear units, positioning stages, motion controllers, software, training and comprehensive after-sales support.
