A new line of linear actuators complete with StepSERVO™ equipped integrated motors has been released by Applied Motion Products Inc. (AMP) as all-in-one linear positioning solutions including drive electronics and controls, housing and bearing support. Available from Mclennan, their European distribution partner, the new StepSERVO Smart Actuators are variously available with NEMA 11, 14, 17 or 23 frame motors configured with built-in ball or lead screw mechanics. 

Smart Actuators -
MLA/MCB moving carriage (left),
MLT pushrod (bottom right) and
Screw Motors (top right)

The MLA and MCB series are moving carriage designs whilst the MLT series is a pushrod-style actuator. AMP’s well proven StepSERVO™ technology combines a digital closed-loop servo drive, encoder feedback and several options for motion control and communications in a single integrated package that delivers more torque, acceleration, speed, accuracy, and efficiency over conventional open-loop stepper motor systems.

These new compact and space saving actuators are based around AMP’s wide range of Screw Motors - hybrid stepper motors where the standard motor shaft is replaced with a lead screw assembly. MLA- and MCB-Smart series linear actuators feature an extruded aluminium rail and support system with a moving load carrying carriage. These versions are available in NEMA frame motor sizes 11, 14 and 23. Users can choose various ball/lead screw pitches and nut material options with leads from 1 to 10 mm to suit their positioning resolution and speed requirements – speeds up to 100 mm/sec are available. The largest actuator, with its 23-frame motor, has a maximum stroke of 250 mm and a maximum load capacity of 7 kg horizontal and 4.4 kg vertical. The direct integration of the screw into the motor allows a coupling-free design that saves space for a more compact solution. The MCB version includes a dust seal and fully shrouded motor whilst the lower cost MLA offers is an open-frame housing design for use in clean environments. Both version include mounting fixtures.

The MLT series pushrod style actuator is also based around the AMP’s Screw Motors in NEMA 11 or 17 frame sizes. Well suited for miniature push, pull, lift, and press applications, a choice of lead screw or ball screw mechanics provides users with a wide scope of cost vs. performance options. The largest MLT actuator can deliver a thrust force up to 300 N and speeds to 250 mm/sec with low vibration and low noise operation. AMP’s Screw Motors are available as separate components without StepSERVO for use with independent drives and controls.

These new StepSERVO™ Smart actuators utilise AMP’s closed-loop stepper technology for direct on-board motor drive, programming, and optional networking. This decentralised approach sees benefits in reduced installation cost through minimised machine wiring, faster machine build and design time and a control concept that is complementary to Industry 4.0. The new Smart actuators are available with a wide choice of control options including step/direction, +/- 10V DC torque/velocity and positioning as well as AMP’s Q Programming which provides streaming commands with maths and machine I/O control functions.

Miniature integrated motor.

Applied Motion Products (AMP)  has launched a Power over Ethernet (PoE) enabled integrated miniature microstepping motor package that combines a closed-loop digital drive, feedback encoder and an Ethernet-supported motion controller as a single-cable positioning solution. With PoE linked drive/controller power and Ethernet communications over a single cable the unique TSM14POE series, based on AMP’s well proven StepSERVO™ technology, will bring a new level of application capability for miniature decentralised automation tasks with time and cost savings through simplified wiring as well as compactness and location flexibility.

Available through Mclennan - AMP’s European distribution partner – the NEMA size 14 integrated motor could be applied to existing PoE-linked devices such as IP Camera systems to add positioning capability, or to miniature automated devices such as robotics, end effectors, small actuators and medical instruments.

AMP’s StepSERVO™ technology provides greater torque, higher acceleration rates, better efficiency, decreased motor heating, and less audible noise than traditional, open-loop step motor systems. For the new TSM14POE series the drive stage is combined with an integral 4096 ppr magnetic encoder providing high accuracy position and speed feedback through a choice of industrial Ethernet protocols including Ethernet TCP/IP, EtherNet/IP and Modbus TCP. Motion control via AMP’s Q Programming language enables axis positioning plus motion profiles with maths and conditional functions available along with stored program execution for machine interaction over Ethernet.

The TSM14POE is compatible with IEEE 802.3at Type 2 specifications for PoE+ and with switches and injectors that support the standard. A choice of models offer X-coded M12 or modular RJ-45 connectors for application flexibility. Both have square nominal housing dimensions of 35 mm x 35 mm with the slightly longer M12 connector option being approximately 109 mm, and 99 mm for the RJ-45 option. Speed and torque characteristics are application dependent with nominal holding torque in the region of 0.4 Nm. Additionally, AMP and Mclennan offer the TSM14POE series complete with integrated low-backlash planetary gearheads in a wide range of ratios where increased torque performance is required.

TSM series stepServo™ integrated motors are also available in larger and smaller frame sizes with conventional power supply requirements. Users can choose from NEMA size 11 to 34 packages with torque output from around 0.1 to over 8 Nm with a wide selection of control and interfacing options. Motor speeds up to 3600 rpm and encoder resolutions of 20,000 counts/rev make the range suitable for a very wide range of motion control applications.

Capacitive encoders as alternative for stepper motor stall detection.

Applied Motion Products Inc. (AMP) has recently announced an alternative encoder technology for microstepping motor position verification. Available from Mclennan, AMP’s European distribution partner, capacitive encoder technology offers advantages for applications where increased durability or space savings are required.

Whilst stepper motor based motion control systems are inherently open loop, more and more applications require the added security and peace of mind provided by encoder position feedback where lost motion might be problematical. Mclennan addresses this need through a wide range of microstepping drives and compatible motor systems from AMP that provide position verification and/or eradicate stall problems for improved performance. Up until now optical encoders have been available as the feedback components of choice but AMP has recently announced this new range of competitively priced capacitive encoders for use on its NEMA 17, 23, and 24 frame stepper motors.

The analogue characteristics of the capacitive-reactance technology used in these new encoders is converted into digital pulses for speed and position feedback and as such offer the same electrical output as their optical counterparts, so that no difference is required for matched microstepping drives. With 2000 pulses per rev available as standard and with a nominal 5V signal level and A+B & Z channels, the encoder is easily integrated across all of the AMP intelligent microstepping drives that offer stall detection or position verification.

In applications where dust, oil, and other contaminants may be present optical encoders can be susceptible to signal level degradation or signal loss whereas capacitive sensors are generally more robust and unaffected in these environments. AMP’s capacitive sensors are pre-assembled onto rear shaft of the motor and with a thinner profile than the optical encoder equivalents a small amount of axial length saving can be achieved in very space restricted installations.
