Multiturn Encoders

POSITAL (Hamilton, NJ) introduced 22-mm multiturn kit encoders for miniature motors and drives. The absolute position feedback devices provide full multiturn measurement capabilities without the need for backup batteries. The rotation counter system is self-powered, so in the event of a power failure or control system outage, the encoder’s counter circuits remain operational, maintaining a record of any rotations that the motor drive shaft experiences. Once power is restored, the motor’s complete rotary position, including rotation count, is forwarded to the central controller. Vendor-neutral SSI and BiSS C communication interfaces are supported.

Extrusion Head

Guill Tool & Engineering (West Warwick, RI) introduced the 500 Series crosshead extrusion head with mechanically assisted gum space adjustment. It is designed for the flow characteristics and processing challenges of elastomeric compounds. The gum space adjustment allows the operator to make an adjustment from a single point using a common socket wrench. The visual indicator on the core tube allows the operator to see how far the gum space has been moved. A half rotation of the cam nut is required to loosen and automatically extract the deflector from the head body.

Automation System

Methods Machine Tools (Sudbury, MA) offers the JobShop Cell PRO automation solution incorporating a main enclosure with several different pre-engineered end-of-arm and infeed/outfeed options. It features an industrial-grade, articulating FANUC 6-axis robot in an aluminum enclosure that allows a RoboDrill to be placed on the left or right side or in a twin cell with two machines. Removable panels on the common enclosure allow for several different infeed and outfeed options including conveyors, drawers, lazy susan style pallet systems, and interfaces for vibratory and other bulk feeding solutions. The RoboDrill offers multi-axis simultaneous machining with a 10,000 or 24,000 RPM BBT-30 spindle. Customers may choose from a 3, 4, or 5-axis configured RoboDrill and an array of standard hydraulic or pneumatic workholding options.

Brushless DC Motors

Nanotec (Feldkirchen, Germany) introduced the APBA80 series of brushless DC motors with a rated power of up to 1.000 W. They come standard with integrated encoder or with encoder and brake and are rated IP65. They have a peak torque of 9.6 Nm, a rated speed of 3,000 rpm, and a rated voltage of 48 V. In addition to the standard version with keyway, individual shaft modifications are possible as are customized windings. The control electronics can be tailored to specific applications. The motors are suited for battery-powered applications such as AGVs or service robots and are safe for use in environments where standard AC servos would require additional insulation and safety measures.
