Positioning Controllers

maxon motor (Fall River, MA) offers the EPOS4 controller module with detachable pin headers and two different power ratings. With a connector board, the modules can be combined into a ready-to-install solution. The position controllers are suitable for control of brushed DC motors and brushless BLDC motors (EC motors) with Hall sensors and encoders up to 750W continuous power and 1500W peak power. The CANopen positioning motor controllers are available with Ethernet-based interfaces such as EtherCAT, or absolute rotary encoders. Features include Field Oriented Control (FOC) with multiple analog and digital I/O, along with various command options. Start-up and parameterization are performed with the EPOS Studio intuitive graphical user interface and user-friendly, menu-controlled wizards.

Fan Controller

Orion Fans (Dallas, TX) offers the OA11/22 fan speed control unit that provides precise airflow control. The field-adjustable, dual-channel phase control unit allows the user to control fan speed for single or multiple fan assemblies. The control units are designed for use with any AC fan or fan tray. The 120/220 VAC speed control unit allows users to specify and control fan noise, speed, and air delivery according to specific application requirements. Four user-adjustable speeds (off, low, medium, and high) allow for maximum control and flexibility with minimum setup time. The unit is designed with fan trays and equipment racks in mind, where noise versus airflow needs to be controlled according to immediate needs.

Position Sensors

TE Connectivity (Pennsauken, NJ) announced the HLIR 750 intrinsically safe, 4-20 mA LVDT position sensors that are CSA listed for use in hazardous locations and where an intrinsically safe sensor is required. With stainless steel construction and a hermetically sealed sensor body, these LVDT position sensors provide contactless position measurement for critical applications in gas turbines for fuel valve position feedback, vane pitch servo controls, governor controls, and generator shell expansion measurement.

Feedback Cylinder

The Series 6PF positioning feedback cylinder from Camozzi Pneumatics (McKinney, TX) is equipped with a potentiometric transducer of a linear position integrated inside the rod. This type of cylinder, when used with the LRXA4 proportional servo valve, makes it possible along the entire stroke to constantly control the position of the rod. The pistons are equipped with specific seals for increased accuracy, and a permanent magnet in order to use external end-stroke sensors. The cylinder is suited for use in tensioning cylinders, positioning cylinders, and filling/cutting/measuring systems. Features include bores from 50 to 125 mm, standard strokes from 50 to 500 mm (50-mm intervals), ISO 15552 compliance, protection class IP67, and assembly with standard ISO accessories.

Brake

SEPAC (Elmira, NY) announced the Thin Spring Engaged Brake, a thin-body, spring-engaged, power-off brake. The brake offers reversible mounting with the shaft extending past the brake or within the brake body. The friction disc/rotor and hub are manufactured from lightweight metal, allowing for lower inertia. A splined hub for shaft connections typically provides less than 1.5° backlash. The brake is suited for servo motors/systems, medical apparatus, robotics and imaging equipment, material handling, semiconductors (wafer handling equipment), energy-related (wind, petroleum, etc.) actuators, and security-related actuators for doors, gates, and curtains.
