Physik Instrumente announces NEXACT Ceramic Linear Motor

PI (Physik Instrumente) introduces the N-310 NEXACT miniature ceramic linear motor actuator.

Features & Advantages:
• Very Compact (25x25x12 mm) and Cost-Effective
• Non-Magnetic and Vacuum-Compatible Design, Self-Locking
• 10 N Push/Pull, 20 mm Travel, 10 mm/sec Speed
• Picometer Resolution
• Very Stiff Design, Millisecond Response & High Bandwidth

Typical Applications: Laser Tuning, Nanotechnology, Nano-Imprint, Semiconductor & Data-Storage Test & Production Equipment, Nanomanipulation, Bio-Technology.

New Design Bridges the Micro / Nanopositioning Gap, < 1/2 Cubic Inch
NEXACT is a patented, high-precision linear motor actuator developed to bridge the gap between micro- and nanopositioning devices. At ½ cubic inch and 50 g (1.7 oz), the new NEXACT actuator is significantly smaller and more cost effective than its big “brother.” This high-force ceramic motor, dubbed NEXLINE has already won a technology award from the semiconductor community.

Working Principle: Piezo Bending Elements Drive a Ceramic Runner
NEXACT actuators provide piezo-class resolution (far below one nanometer) and millisecond responsiveness. The new technology combines virtually unlimited travel ranges with high stiffness in a very small package. In operation, piezoceramic bending elements act on the ceramic runner, connected to the moving part of the application. The length of the runner can be chosen as required, force capacity, resolution and velocity depend on the piezo geometry and are also scalable. To move the runner over longer distances the stepping mode is used, whereas for distances smaller than 7┬Ám, the linear (sweep) mode enables high-dynamics positioning with resolutions far below one nanometer. The special drive design reduces the operating voltage to 40 V and below.

Self-Locking, No Wear, Maintenance-Free
In contrast to servo or stepper motor actuators, the piezo stepping elements effect linear motion directly, without the need to transform rotation with gears and leadscrews. Backlash and wear are eliminated and the drive is maintenance-free. NEXACT actuators exhibit high stiffness and are self-locking when powered down with nanometer position stability, and zero dissipation or servo-dither at rest.

Siemens introduces Sitrans LUC500 duplex lift station control

Siemens Energy & Automation, Inc. introduces the Sitrans LUC500 ultrasonic controller, an advanced ultrasonic level controller, for duplex lift stations run by operators of water and wastewater plants. The design of the new controller, integrates common PLC lift station functionalities into one pre-configured unit that improves efficiency, reduces energy consumption and lowers maintenance costs by decreasing pump failures and site visits. The Sitrans LUC500 ultrasonic controller replaces the EnviroRanger ERS 500, maintaining the same proven features and benefits.

The Sitrans LUC500 unit combines non-contacting ultrasonic technology, echo-processing techniques and proven application software to provide accurate level control of liquids in wet wells up to 50 feet deep. It also monitors flow in flumes, weirs and other open channels.

The Sitrans LUC500 controller features fault monitoring and data logging for trend analysis, logging time, date, volume or any other application event.

It integrates seamlessly with Scada, PLC, or DCS systems to provide remote access to all system parameters including pumped volume, pump runtime and pump status. The Sitrans LUC500 unit provides up to 16 digital inputs for pump interlocks for pump faults (thermal, seal failure), power failure, pump run status and H/O/A (Hand/Off/Auto) switch. The integral telemetry interface for Modbus RTU/ASCII allows remote control in real time. The patented algorithm for calculation of pumped volume works within 5 percent accuracy. Furthermore, the level controller offers logging of pump runtime and number of pump starts, as well as an energy saving function with built-in real-time clock. In the Sitrans LUC500, five relays control any combination of pumps, gate valves, and alarms. A pump performance/efficiency monitoring function calculates the pump capacities each time the pumps operate, and compares these to the reference pump capacities set by the user. If the monitored pump capacity falls below the entered reference value, an alarm indicates operational error, detecting complete pump failure.

Additionally, the Sitrans LUC500 instrument is expandable to meet a variety of applications with I/O modules RAM for data logging, dual point measurement, and industrial communications, including Profibus DP. Optional Windows based software, Dolphin Plus, provides simple system configuration and diagnostics. The device is available for rack mount, panel mount or wall mount.

Driver ICs Elevate Design of Stepper-Motor Control

Stepper motors are now being used more frequently in industrial environments. Increased performance and reduced size make them increasingly attractive, and their application is no longer limited to accurate positioning. Applications such as dose pumps, valve control and even dynamic positioning (and other movements previously reserved for linear positioners) are becoming popular.
The drive electronics for such stepper motors are evolving accordingly. In the traditional way, the architecture typically includes a standard microcontroller or DSP, custom logic to provide the decoder inputs, several analog-to-digital and digital-to-analog converters (ADCs and DACs), and an H-bridge to drive the currents in the stator windings of the stepper motor.

The development of drivers and controllers spawned by automotive applications has yielded interesting products and building blocks. These functions move local intelligence close to the motor, creating a class of products known as mechatronics. Application-specific standard products (ASSPs) have become available to drive stepper motors directly from high-level position commands on a bus. Single-chip solutions integrate driver transistors, on-chip current regulation, a translation table between the exact rotor position and corresponding coil currents, a rotor positioner, speed and acceleration, and the physical layer and data-link protocol of a communication bus. The use of microstepping converts low-resolution motors into low-cost high-resolution actuators.
These single-chip motor-driver ASSPs are convenient for multi-axis positioning applications. However, system builders who want more flexibility on the control of the movement can choose dual-chip solutions. These solutions allow system designers to embed their knowledge in standard microcores or DSPs, and develop algorithms that produce the “next-step” signals to the stepper motor. The ASSP takes care of the rest and replaces the bulk, if not all, of the traditional motor-drive circuitry. This allows designers to concentrate on the programming of the motion, rather than concentrating on driving a current through a coil using complex PWM algorithms. The development time, and therefore the time-to-market, of new products reduces accordingly.
The ASSPs come with new features like embedded diagnostics and information on torque and motion. The designer can use these signals in programming the controller to detect rotor blockage and rotor position, and to perform automated adaptation of torque without the use of external sensors.
