MLA series miniature linear positioning actuators from Applied Motion Products Inc. (AMP) are based around NEMA 11, 14, 17 and 23 frame stepper motors and can be configured as motor-only open-loop variants or supplied complete with the USA-based motion control leader’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 ballscrew mechanics or, where improved backlash is required, a patented Constant Force™ leadscrew option featuring a self-adjusting polymer nut arrangement. A comprehensive choice of options covering motor and motion control system, fitted brakes and encoders, precision grade, and working stroke make the MLA series extremely customisable.
The four MLA actuator models cover stroke lengths from 10 mm up to 300 mm in both leadscrew and ballscrew 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 100 mm/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 25 mm. The largest MLA42 model, based on the NEMA23 frame stepper, has a width of 62 mm and height over the carriage of 35.5mm. The maximum load capacity for this model is based on the leadscrew/ballscrew pitch with a maximum of 7 kg horizontal and 4.4 kg vertical.
The StepSERVO versions of the MLA actuator range are available on the three larger models. This proven closed-loop stepper technology with its integrated motor drive, programmed control, and optional networking provides a decentralised solution for positioning systems with benefits of 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.
