Motion Control

Positioning Assemblies

UniSlide assemblies from Velmex (Bloomfield, NY) deliver movement in one, two, or three dimensions with linear motion. The systems also can be customized for specific requirements. They are compact, and the design allows for construction of multi-axis systems. They are available in an array of standard manual or motor-driven models and sizes, including linear assemblies, elevating tables, and XY tables. They can be customized with rapid/fine motion, thumbscrew locks, special finishes, way covers, revolution counters, position encoders, or other options. The assemblies are constructed of a hard aluminum alloy and PTFE bearings. Linear UniSlides have a maximum load capacity up to 400 pounds horizontally, and 100 pounds vertically. Straight-line accuracy with precision lead screws is 0.0015" per 10" or better of the screw motion. The elevating tables and XY tables can lift up to 100 pounds.

Linear Position Sensors

H. G. Schaevitz Alliance Sensors Group (Moorestown, NJ) introduced the LR-19 series inductive linear position sensors. The contactless devices are designed for factory automation and a variety of industrial or commercial applications such as motor sport vehicles, automotive testing, solar cell positioners, wind turbine prop pitch and brake position, and packaging equipment. They are offered in six full-scale ranges from 25 to 200 mm. Operating from a variety of DC voltages, the sensors offer a choice of four analog outputs and include proprietary SenSetTM field recalibration.

Stepper Motor

Lin Engineering (Morgan Hill, CA) released the Xtreme Torque E5618 stepper motor that has been designed to reduce stalling, skipped steps, and provide efficient torque. The new design allows users to stay within the same frame size. The NEMA 23 stepper has a holding torque of 150 oz-in and is suited for applications with heavier loads or at increased risk of stalling or skipping steps. It also allows for an integral connector or flying lead wires.

Motor Driver ICs

Toshiba America Electronic Components (San Jose, CA) offers four motor driver ICs, ranging from precision stepper motor drivers to sensorless brushless DC motor drivers. The TB67S269FTG bipolar stepping motor driver has a maximum rating of 50V and 2.0A. Three brushless DC motor drivers — the TB67B001FTG, TB67B008FTG, and TB67B008FNG — feature maximum rating of 25V and 3.0A. The TB67S269FTG targets applications requiring high-speed, high-precision motor drives. The driver’s high-resolution, 1/32-step motor driving technology lowers noise and vibration, while heat generation is reduced via low ON resistance (0.8Ω or less, upper + lower) MOSFET H-bridges and featuring Toshiba’s Advanced Mixed Decay (ADMD) technology that optimizes the drive capability of complex motor currents.

Encoders

CUI (Tualatin, OR) offers the AMT31 modular encoder series that generates standard U/V/W commutation signals for vectoring current to brushless motors. Positional information is generated using a patented capacitive code generation system coupled with a proprietary ASIC. The encoder is designed for use in brushless dc motor applications subject to vibration and contaminants such as dust, dirt, and oil that typically stop optical encoders from working effectively. They deliver accuracy of ±12 arcmin (±0.2 mechanical degrees). Twenty programmable resolutions are available with a range of 48 to 4096 PPR.

AC Drive

The VACON® 100 FLOW from VACON (Milwaukee, WI) is an AC drive designed to improve flow control for multi-pump applications in which several pumps are used in place of a single one. The drive offers control of flow and pressure for a maximum of eight pumps (or fans) without the need for an external controller — communication between drives is provided by integrated RS-485. It is equipped with built-in Ethernet as standard, eliminating additional options or gateways needed to communicate with process automation. The drive offers three multi-pump control solutions: single-drive multi-pump, multi-drive multi-master, and multi-drive multi-follower.
