Santa Clara, California – Animatics Corporation, through OEM Dynamics Linear Division, has expanded its product line into the Linear Actuator market with the release of the Harmonic Linear Drive Series.
The Harmonic Linear Drive™ (HLD) is an innovative linear belt drive solution providing high accuracy and low cost without the need for a gearhead or brake. Instead of using a fixed belt to move the load, the HLD uses a recirculating belt, folded back upon itself and routed over subtly different diameter pulleys yielding gear reduction by way of the Harmonic Drive Principle, without the cost or backlash of a separate gearhead (see animation at www.oemdynamics.com).
The HLD is available in standard stroke lengths from 100mm to 3200mm and equivalent pitch ratios from 2.5mm/rev to 12.5mm/rev. Custom strokes are available. These fully integrated units are shipped with the patented Animatics SmartMotor technology to provide an all-in-one Closed-Loop Brushless Servo Motor, Drive Amplifier, Optical Encoder, I/O, Field bus option, belt actuator and bearing support.
The HLD60 produces standard thrust up to 450 Newtons, with an average moment loading of up to 150Nm. Each unit provides a near Zero Backlash solution with bidirectional repeatability approaching 60µm and unidirectional repeatability of less than 20µm.
HaydonKerk Motion Solutions introduces its Haydon™ specialty Clean Motor product. Designed for contamination sensitive applications, cleanroom environments, and environments within systems under high vacuum, HaydonKerk’s Clean Motors are designed to limit contaminants and out gassing in vacuum environments. Provided that the motor operates below its rated maximum operating temperature, Haydon™ Clean Motors will survive in a vacuum down to 10-8 Torr.
To ensure the minimum amount of out gas in a vacuum environment, the Clean Motor product undergoes special handling and uses parts fabricated in a proprietary process. Clean Motors are constructed of non-volatile materials, thoroughly cleaned using ultrasonic equipment, and then vacuum-baked at high temperature to extract contaminants. In addition to Teflon® wires and high temperature windings, Haydon™ Clean Motors contain stainless steel bearings with special lubrication. Out gassing results from a lack of motor cleanliness, often created by contaminants present during the manufacturing process and even the slightest contact with a human hand. The Haydon™ Clean Motor products are processed to consider all possible contamination sources and are then sealed in double bags for handling under clean-room protocols.
CUI Inc has added three low cost, high performance optical encoders to their broad encoder product offering. The AME, BME, and LME are modular incremental encoders that offer a wide range of resolution and bore options, and can provide voltage or line driver output.

Other motors in this series are offered in shorter lengths of 1.256” and 1.556” with the capability to achieve continuous torque up to 0.80 oz-in and 1.3 oz-in, respectively.
Depending on model, these motors can generate maximum peak torques up to 10.2 oz-in and nominal no-load speeds up to 8720 rpm.
Key features include sintered bronze bearings, 2-pole stators, heavy-gauge steel housing, silicon steel laminations, and copper graphite brushes. Standard available options include ball bearings, EMI/RFI filter networks, and leadwire or terminal connection configurations.
Planetary gearboxes can be specified to meet demanding speed and torque requirements and optical encoders with several choices of resolution can be added for position, velocity, and direction feedback necessary in precision motion control applications. Custom motors can be developed to suit particular application requirements.

Lyman, SC – SEW-EURODRIVE has engineered a new line of AC motors with modular components that can be configured to comply with any nation’s energy efficiency standards. The new DR family of motors will replace all other AC motors in SEW’s product line in 2009, providing engineers around the world with optimum energy-saving solutions for any application. The compact new motors can be integrated into SEW gearmotors, used as stand-alone motors or in decentralized control architectures.
SEW, which has been manufacturing motors since it was founded in Germany in 1931, was the first company in the world to manufacture industrial AC motors using die-cast copper technology. Since that breakthrough in 2002, SEW has been working to create a new generation of energy-efficient motors using materials like copper to lower electrical resistance and new designs to reduce energy losses in operation. Copper rotor cages, for example, allow a motor’s power rating to increase while maintaining its efficiency level, enabling the same motor size to produce more power.
DR motors will be available in three versions – a standard model and two high efficiency versions. The standard model is designed for high cycling applications like material handling and packaging, where frequent starts and stops would counteract any energy savings that could be gained from using a premium efficiency motor.
One energy efficient version meets the requirements of NEMA Premium for the U.S. market and the other complies with the efficiency requirements of other countries, including the new IEC motor standard that will take effect in Europe in 2011.
The new DR motor series also addresses industry requirements for small, compact and decentralized drive solutions for material handling and transportation systems. SEW’s modular approach to product design allows engineers to select exactly the right motor, drive and gear unit combination to maximize energy savings in every application.
In another engineering innovation, SEW engineers integrated an encoder into the fan rather than at the end of the motor to help achieve a compact footprint. This built-in encoder is fully integrated into the motor, reducing the cost and complexity of encoder engineering. The simple encoder design also makes it easy to retrofit.
Many tasks require only simple positioning and velocity detection. Since high-resolution encoders installed on the non-drive shaft end are often too complex for this task, SEW has developed several fully integrated and affordable encoders for the DR motor with a resolution between one and 24 pulses per revolution. For high-resolution applications, standard-mounted encoders have been equipped with a new, simpler connection. Input shaft assembly makes for easier encoder changes. Several encoder types including sin/cosine, HTL, TTL, RS485 and others are available.
The modularity of the DR motor series is also reflected in a new braking system, which for the first time allows three different brake sizes to be used with a single motor size. Since many applications don’t require full braking torque, this modular approach provides choices, which can equate to cost and weight reductions. The new brakes are quieter and, since they are mounted on a friction plate, can be easily removed for maintenance or resizing without disassembling the motor. Sensors make monitoring for wear or operation simpler. As an alternate to a “holding brake,” a backstop with high locking torque can also lock the rotation of the motor in one direction.
