LONGER LASTING, DEEPER DRILLING
DII15-60-200A is a 1.5-inch diameter, high-pressure, high-temperature (HPHT) brushless DC (BLDC) motor that provides the ideal solution for severe, downhole applications, such as mud-pulser valves, caliper deployment and sensor positioning. The motor has been successfully tested to operate under continuous duty in temperatures up to 205 ºC and pressures up to 30,000 psi. DII15-60-200A also features integral Hall commutation, and uses rare earth magnets to support high operating efficiencies and corrosion resistance. It's designed to withstand shock to 1,000 Gs and vibration to 25 Gs, and is built to endure the most extreme environmental conditions. DII15-60-200A also can be customized for gearbox or other feedback device options, and winding variations are offered to meet a wide range of controller voltages and currents.

SC9000 encapsulated power-pole (EP), arc-resistant, adjustable-frequency drive is reported to be the first fully integrated, arc-resistant, medium-voltage (MV) drive certified to Canadian Standards Association's (CSA) C22.2 No.22-11 standard, and witness-tested to the Institute of Electrical and Electronics Engineers' (IEEE) C37.20.7 standard through extensive assessment at a third-party laboratory. It's engineered with a robust, arc-resistant, Type 2B enclosure to provide the strength needed to resist forces of arc events up to 50 kiloamperes (kA). SC9000 also meets the IEEE 519 guideline for harmonic control and reactive compensation of static-power converters. It's also certified to Underwriters Laboratories' (UL) 347A standard for MV power conversion equipment, as well as Canadian Underwriters Laboratories' (cUL) standards, and it's restriction of hazardous substances (RoHS) compliant.
MORE STEPPER FRAME SIZES
PMX series stepper motors are adding smaller 08, 11 and 14 frame sizes to their traditional 17, 23 and 34 frame sizes. The also feature: minimal drive adjustments with options for 1.8° and 0.9° step angles; flexible manufacturing, including immediate evaluation of small modifications and co-engineered solutions for swift delivery and prototyping; local technical support, offering motion expertise and improved delivery for meaning quicker time to market and less downtime; and easy worldwide application with CE, RoHS and REACH compliance.
Direct-drive, hollow-shaft motors increase speed and acceleration, while providing better accuracy and faster response times compared to motor-driven, mechanical arrangements. In applications appropriate for direct-drive, hollow-shaft motors, the time of a move may be reduced by up to 80% from approximately 50 milliseconds to less than 10 milliseconds. High repetition rate positional moves are sensitive to inertia matching and types of coupling, in addition to harmonic vibrations in the mounting structures. Hollow-shafted motors are available for extreme environments, including vacuum/space, waterproof/deep sea, radiation-resistant and others.

LOW-COST, CORROSION PROTECTION
PAT 44X-10 series compact, lightweight, low-cost, NEMA 4X-rated DC drives are designed to deliver longer life, better performance and higher corrosion resistance. They accept 115- or 230-V AC inputs for operating 90- and 180-V DC permanent-magnet or shunt-wound DC motors (50, 100 and 200 V DC field voltages) from 1/8 to 2 horsepower. PAT series has the same bolt-in form factors as competitive drives to make changeover easy and cost effective. They also feature power and current-limit LEDs, line fuses, inhibit pins for remote start/stop, and a front-cover-mounted speed potentiometer and on/off switch. Setup is simple with trimmer pot adjustments for minimum speed, maximum speed, acceleration, deceleration, IR compensation and current limit.
