Motor/Motion Controller offers high resolution, smooth operation.

January 16, 2015

Featuring full motion controller and GeckoMotion software compatibility, UL-Recognized GM215 runs up to 4 axes of coordinated motion off of onboard flash memory. Unit operates step and direction input step motor drive and offers 10 microstep native resolution. Each full step angle is divided into 10 equally spaced microsteps. Motor morphs from sine-cosine motor currents at low speeds (from 240 rpm) to square-wave currents at high speeds (ending at 360 rpm). Read More

AC Motor Speed Control drives motors rated up to 1 hp.

December 31, 2014

Housed in NEMA-4X/IP65 aluminum die-cast enclosure, Model 2999 Pacesetter™ is suited for stand-alone AC gearmotor applications that require variable speed, controlled acceleration, and reversing. Unit drives 230 Vac, 50/60 Hz, inverter-duty 3-phase gearmotors and motors rated up to 1 hp/746 W. Allowing for up to 200% starting torque, control ensures startup of high frictional loads. Slip compensation with static auto-tune and boost circuitry provides load regulation over wide speed range. Read More

12 V Motor Drivers eliminate stepper and brushed DC motor tuning.

December 16, 2014

Respectively available in 24-pin, 4 x 4 mm QFN package and 16-pin, 5 x 6.4 mm HTSSOP, DRV8846 and DRV8848 reduce spin-up time to seconds. DRV8846 incorporates adaptive current control technology and 1/32 micro-stepping indexer to automatically tune motor performance for precise, smooth, and quiet motion. DRV8848 can operate without current sense resistors and simplifies designs by using PWM control interface and minimal external components. Both models are fully fault protected. Read More

Variable Speed Pump Drive provides high dynamics.

November 11, 2014

Covering wide performance range up to 120 kW, Sytronix SVP 7010 offers comprehensive selection of hydraulic-specific functions and can be used in both open and closed loop hydraulic circuits. Control can eliminate pressure overshoot and position linear axes to high degree of accuracy, without instability. Algorithms allow for reduction of pressure ripple inherent in certain pump designs. To save energy, drive reduces pump speed during idle and partial load operation. Read More

High-Speed Drives target vertical lathes.

October 24, 2014

Using planetary reducers, high-speed versions of DRP, KRP, and KRPX Drives simplify design of mechanical transmission systems of both large rotary tables used on vertical lathes over 2,000 m and smaller tables used on milling machines. When meshed with drive gear, reducers on TwinDrive and DualDrive solutions cancel 100% of backlash. Reducers have been hardened to allow continuous operating cycles and can achieve rotational speeds up to 28 rpm-1. Read More
