Mclennan's motion control range grows with new Allied Motion product lines

26 August 2010

The long-standing distribution partnership between Mclennan Servo Supplies and Allied Motion Inc. has been extended with the Surrey based mechatronics specialists increasing its product line coverage of the prominent USA and European motion control manufacturers direct-drive torque motors, brushless servo motors, high performance servo drives and encoders.


Mclennan's close relationship with the Allied Motion group spans more than 30 years with many thousands of successful small & precision brushed and brushless motor applications for Premotec B.V. of the Netherlands – now one of four Allied Motion engineering/production companies or Technology Units. The new partnership aims to build a similar success with Allied Motion's Emoteq/COPI Technology Unit and will work across all of its products which include frameless and housed torque motors up to 2000 Nm, Quantum NEMA frame servo motors, X-Drive digital servo amplifiers, and ultra high resolution incremental encoders.

As well as a long history of success with Premotec, Allied Motion chose Mclennan because of its foothold in many market areas they target including Aerospace & Defence, Medical Device, Semiconductor & Electronics, and Scientific Research. Vic Sayer, Managing Director of Mclennan says, "We are very excited about working with these new Allied Motion products. We have an excellent reputation with Premotec's small and precision DC motor range and the Emoteq/COPI products offer similar flexibility with a strong standard range and the ability to custom engineer product - even for small quantities."

Highlights of the new products for Mclennan include the Megaflux range – large frameless and separate rotor/stator servo motors, up to 790 mm in diameter with as much as twice the power density and five times the speed ratings of competitive units. These motors are characterised by a high pole count that maximises torque output and rotational smoothness. The housed versions of these motors, complete with bearing system, commutation and position feedback device are aimed at direct-drive high precision motion control in demanding automation applications such as robotics where the large through aperture may be used to feed services such as electrics, optics or pneumatics.

Allied Motions ultra-high resolution encoders can provide outputs up to 5 million counts per rev for an angular resolution of less than one arc second. The technology does not compromise the speed bandwidth which is often found with other manufacturers high resolution encoders – (e.g. 250,000 counts per rev at 3750 RPM).

Allied Motion's Enduramax integrated-drive brushless DC motors include the rugged 75 mm diameter BE 30 model which includes single or dual shaft versions for a wide range of commercial applications such as pumps, fans or actuators. With its integral 12 V or 24 V BLDC drive, the Enduramax is available with optional CANopen bus control, various environmental protection options and automotive style electrical connection for simplified fit and forget installation.

The new X-Drive all digital AC servo drive is capable of providing up to 16 A continuous current for brushless servomotors and torque motors up to 4.7 kW power rating. With its integral direct-on-line power supply (110 – 240 VAC) and generous I/O complement, the X- Drive will suit a wide range of servo motion control applications.

Mclennan works closely with a small number of global motion control manufacturers such as Allied Motion and has assembled an impressive range of DC, stepper and servo drive technologies together with motion controls, and 3H3using its own in-house design and manufacturing capability, is able to offer complete integrated mechatronics assemblies with customised mechanics and other power train components.
