Motors & Drives

A range of brushless servo motors with a separate rotor and stator design, aimed at the smooth precise control and direct-drive of large inertia or high torque loads, is available from precision motion specialists Heason Technology Limited. The Megaflux thin-ring torque motor from USA manufacturer Emoteq Corporation has an inherently large diameter-to-length ratio - from 150 mm x 30 mm to 760 mm x 123 mm – and covers continuous stall torque from 3 Nm to over 2000 Nm.

For low speed stop/start applications under load the Huco Dynatork piston air motors continue to prove the ideal choice. Their very nature makes them prime candidates for operation in hazardous or sensitive environments such as hydrocarbon engineering, paint manufacture, paper conversion, wood working and food processing.

Parker Hannifin has extended its family of Compax3 drives with the launch of the Compax3M (C3M) servo drive. This new drive has been developed specifically for use with a wide range of multi-axis applications, providing a powerful yet easy to use system that is also extremely compact; indeed, the C3M is believed to be the slimmest servo drive currently available.

A new high-performance motor intended for the OEM market that offers significant savings on running costs and space requirements that can be engineered to match customer applications has been introduced by Lafert. Savings on operating costs can amount to more than 80% whilst the motor’s far superior output to that of standard AC induction motors enables significant frame size reductions plus weight savings.

Danfoss Drives VLT® Series Variable Frequency Drives are now available with power through 1350 HP in 460 and 690 VAC. F1 frame models deliver power up to 1050 HP in an 86.8 in. x 55.1 in. x 23.9 in. footprint, while F2 frame models deliver up to 1350 HP in an 86.8 in. x 71.0 in. x 23.9 in. footprint.

For simple servo applications, QuickSilver offers the SilverDust IGF which features a compact DIN rail mountable design, 7 TTL level I/O (optional 24V with QCI-BO-B52), RS-232/485 serial interface, ASCII/Modbus protocol, and enough memory for several thousand lines of programming. Like the other SilverDust IG controller/drivers, the IGF comes with a built in regenerative braking circuit, single connector to motor, an on/off switch, and status LEDs.

QuickSilver Controls, Inc. expands its line of servo motors with the QCI-A34L-1. The 34L-1 only requires 4.5A which means a single cable can be used for both motor and encoder signals and the servo motor can be driven from a small SilverDust D2 controller.

Armstrong Optical Ltd announces the immediate availability of a new catalogue describing the complete range of extreme resolution positioning and manipulation systems from SmarAct GmbH. The core competence of SmarAct GmbH is the development of miniaturised positioners that meet the highest demands of precision and control.

The latest compact, modular systems drive from Parker Hannifin, the global leader in motion and control technologies, offers system designers a high performance drives solution with more flexibility than ever. Called the AC890, the unit is compatible with virtually any feedback technology, enabling it to be integrated seamlessly into automation networks across a diverse range of applications, increasing productivity and profitability as a result.

Mclennan has launched a new range of intelligent servo drives from California based Applied Motion Products Inc. The packaged BLuAC5 range includes a PWM drive stage with a rating of 5 A continuous/15 A peak and direct-on-line 90-265 VAC input. It may be configured for linear or rotary sinusoidal and trapezoidal commutated brushless servo motors with tuning made very straightforward with AMP’s Quick Tuner™ software which features a built-in digital oscilloscope. The powerful DSP based drive stage may be programmed for torque, velocity, positioning, and programmable (stand-alone) modes.
