Motors & Drives Stepping Motor Series with a High-Resolution Encoder from Nanotec The SC series from Nanotec Electronic is an out-of-the-box combination of a stepper motor with an optical encoder. The first two motors are available in sizes 60 mm (Nema 24) and 41 mm Nema 17. Stepper motors with a mounted encoder have long been available as part of the modular system from Nanotec Electronic. The standard combination is more cost-effective than ordering the products separately and is available from stock. The motors come in sizes 41 (Nema 17) and 60 mm (Nema 24) and have a holding torque of 0.5 and 3.54 Nm, respectively, and a step resolution of 1.8°. The encoder has a high resolution of 4,000 CPR, with quadrature, it can reach 16,000 pulses per revolution. A 5 V and 24 V encoder is available, each with a line driver. The motor and encoder have integrated connectors for simple and fast installation. This combination is well suited for closed loop applications with position feedback. Stepper motors with Nanotec closed loop controls operate more smoothly and have torque, speed and position control. Thus, they can be used in applications that were formerly only reserved for servo motors with gearboxes. ABB Expands Power Range of ACS 2000 Medium Voltage Drive The ACS 2000, ABB’s active front end drive for general purpose applications, is now available with higher power capabilities, up to 3,000 HP. Developed with the latest drive technologies, The ACS 2000 is well suited for general purpose applications where a medium voltage installation is required, such as pumps, fans, blowers and conveyors. Users across many industries including water, wastewater, power, cement, mining and HVAC, can all derive significant energy savings as well as more reliable process control while benefiting from the drive’s compact, lightweight design. The ACS 2000’s direct-to-line connection means it’s transformerless, resulting in a small footprint for space-sensitive applications. The design is packed with technology such as a high voltage IGBT based active front end and patented multi-level switching topology, providing both line and load friendly operation. The ACS 2000 design provides near sinusoidal current and voltage waveforms making the drive compatible for use with standard NEMA rated motors. The installed base for the ACS 2000 of both 4 kV and 6 kV ratings continues to expand in nearly every country in the world with the release of the third 4 kV frame size. In addition to the expansion in power ratings, additional pre-engineered options such as a fused input contactor with disconnect and an auxiliary power transformer have been added to the product line. With the integration of an Active Front End (AFE), line side 14 Summer 2013 harmonics are minimized without the use of expensive, specialized transformers. This ultra low harmonic (ULH) design meets the requirements for current and voltage harmonic distortion per IEEE 519 and IEC 61000-2-4 standards. By actively managing power factor, the ACS 2000 DTL can maintain unity power factor across the entire speed range of the drive while providing valuable energy savings to the end user. In addition, the AFE enables regenerative operation, which feeds back braking energy into the line supply, further reducing overall energy consumption. Reduce Device and Instrument Size, Without Compromising Power with Athlonix 10NS Brush DC Motors Portescap has introduced the 10NS brush DC miniature motor. These brush DC motors deliver improved speed-to-torque performance, ensuring high nominal torque and high power up to 0.7 W in a smaller envelope than motors with comparable performance attributes. This enables OEMs to build smaller, lighter and higher performing machines and devices. It also eliminates the need to choose between compact size and weight, or battery life and equipment life cycle. “As part of the Athlonix platform, ultra-compact 10NS brush DC motors feature an energy efficient coreless design with an optimized self-supporting coil and magnetic circuit. This enables the motor to maximize power density, while also providing sustained endurance over the life of the motor,” said Sunil Kumar, assistant product manager. These high power density motors provide maximum continuous torque up to 0.9 mNm to deliver higher endurance and performance while maintaining operational efficiency. They weigh 16 g / 0.56 oz and deliver output power up to 0.7 watts. The 10NS brush DC motors are compatible with incremental encoders and gearheads of various sizes and ratios to satisfy a wide range of application needs. They are manufactured in an ISO certified facility and are RoHS compliant. KB Electronics, Inc. Introduces a Hybrid Drive Model KBWA KB Electronics, Inc., a manufacturer of AC drives and DC drives from fractional through 5 horsepower, has introduced a Hybrid Drive to their product line. A hybrid, by definition, is the merging of two technologies. These drives combine the digital technology of the microprocessor with an analog interface. Simple trimpot adjustments and selectable jumpers are used in lieu of complicated programming. The KBWA series drives operate on either 115 or 230 VAC. The KBWA-23D is housed in a vented NEMA 1 / IP 20 enclosure and is rated through ½ HP. Model KBWA-22D is housed in a nonvented NEMA 1 / IP 50 enclosure and is rated through ¼ HP. www.e-DriveOnline.com http://www.e-DriveOnline.com
