Original Press Release:


New High Force Linear Motor Offers Improved Force Density and Rugged Environmental Protection


Hauppauge, New York (April 5, 2002) -Anorad Corporation, a Rockwell Automation business, announced today the immediate availability of its new LC family of steel core brushless linear motors. Representing the company's next generation of high force linear motors, the LC product line is distinguished by having both an extremely high force density and an environmentally protected design.

The LC linear motor utilizes a unique patent pending laminated steel core design which has been optimized by Finite Element Analysis (FEA). This allows the coil assembly to have a high
copper fill with improved thermal efficiency. Coupled with the latest generation of magnetic materials, an extremely high force density is achieved. The LC is initially available in two coil
sizes. Model LC-80-240 is 80mm wide by 240mm long and rated at 62 lbf continuous, and model LC-80-340 is 80mm wide by 340mm long and rated at 94 lbf continuous. Other sizes are currently in development, and custom configurations are easily accommodated.

A special feature of the LC linear motor coil is its robust and unique encapsulation method. Unlike other linear motors that have the coil laminations exposed in the air gap, the LC motor
uses a novel molding method that completely encapsulates the face of the motor, thus effectively sealing the laminations. This does away with the exposed interface between steel and epoxy
eliminating a moisture migration path that could lead to motor failure in wet environments.

Adding to the motor's robust design is a heavy duty magnet track. A stainless steel shroud covers the magnets providing additional protection as well as an aesthetically pleasing look.
Magnet track sections are easily butted together to achieve any required travel.

The LC motor is compatible with industry standard 3-phase brushless servo drives. For servo drives that require commutation feedback, an available Hall effect feedback module can be attached to the front of the motor coil. The motor may also be commutated by software with those controls that offer this feature. Anorad offers a full line of compatible servo controls, drives, cables and feedback.

The LC linear motor is ideal for high throughput applications where high force density and robust design is required, such as wafer dicing, electronic assembly, machine tools, material
handling, and water jet cutting.

Anorad has a rich history in linear motor development and manufacturing. The company pioneered the use of linear motors in production positioning equipment for industry. It was the
first to bring to market such novel inventions as the PM brushless linear motor, the cableless moving magnet linear motor with integrated feedback, the 2D brushless planar servo motor, and oil/water cooled machine tool linear motors. Drawing on 20 years of linear motor leadership, Anorad has once again reset the performance bar with the LC linear motor line.

Anorad Corporation, a Rockwell Automation business, produces ultra-high precision positioning stages, motion systems, linear motors and servo controls for demanding original equipment manufacturers in the semiconductor, electronics, photonics. and general automation markets. The company is headquartered in
Hauppauge, New York and has additional operations in Israel, the Netherlands, and Ohio. For more information on Anorad's products and services, visit www.anorad.com.
