Motors & Drives

A hydraulic power head that is attached to the boom of an excavator that is designed to perform such tasks as foundation drilling, screw anchoring and core barrelling typically has multiple hose connections and case drains. Such configurations make them difficult to attach and set-up in the field. They also require the operator to modulate the excavator’s hydraulic output to keep it within the typical 250 l/pm capacity common in these power head units.

Parker Hannifin,has broadened its proven range of bent axis piston units, offering greater choice and flexibility in terms of size, while providing the same high performance operation to boost production output and profitability. The latest addition to the F11 series, the F11-6, has been introduced to offer exceptional degrees of speed, efficiency and pressure in many motor applications, including fan drives, saw motors and construction machinery.

Red Lion Controls, Inc. announces increased functionality and flexibility for their popular G3 Series Operator Interface family, now available with the new Ethernet expansion card, G3ENET. G3 Series HMIs already provide one Ethernet port and now users can add a second Ethernet port to increase bandwidth and separate networks. In addition to supporting ten simultaneous Ethernet protocols, the G3 Series HMIs with the G3ENET card provide unprecedented communication with devices on two distinct Ethernet networks simultaneously—without the need for an industrial router—saving both cost and configuration time. The expansion card can be easily fitted to any G3 series HMI with only a single Ethernet port.

SKF is working with French sports car manufacturer Venturi Automobiles to help develop and manufacture the first production electric sports car in history, the Venturi Fetish.

Parker Hannifin, has launched its latest range of hydraulic motors, developed to improve the efficiency and performance of fan operated cooling systems in both on- and off-highway vehicles. The new M5A hydraulic motors are ideal for use with fan units of up to 20kW, at maximum operating pressures of 300 bar (4500 PSI) and speeds to 4,000 RPM. In addition, they are compact, lightweight and based on proven technology to offer a cost effective and reliable solution for OEM and retrofit applications alike.

Exlar announces the implementation of EtherNet/IP with its Tritex II™ linear and rotary actuators and the accompanying ODVA Declaration of Conformity to the EtherNet/IP Specification. EtherNet/IP is an industrial protocol operating over the Ethernet medium and is used for communication between industrial control systems and their components, such as a programmable automation controller, PLC or an I/O system.

A crane control refurbishment project at Clydeport’s Hunterston terminal relies on Parker SSD AC890 series system drives to deliver pinpoint control in the unloading of coal from vessels. The massive crane can lift up to 36 tonnes of coal in a single grab, allowing loads to be deposited reliably and accurately into the dockside hopper, even in inclement Scottish weather and winds of 40mph or more.

Wachendorff WDGA series CANopen absolute magnetic rotary encoders from Variohm EuroSensor feature a 12-bit singleturn and 12-bit + 18-bit multiturn resolution and are ideally suited to applications where high accuracy measurement, extreme durability and competitive pricing are of prime concern. The WDGA uses Wachendorff's patented EnDra® technology with an integral 32-bit processor which assigns a unique coded magnetic signal for each of the individual 4096 counts/rev and for each full revolution count without relying on wear prone gears or limited life batteries, and so guarantees long life and exceptional levels of reliability – even in arduous conditions.

Rotalink has launched a range of high-torque brushed DC motors with neodymium rare earth magnets. The new RE series delivers at least twice the maximum shaft power of similar sized permanent magnet DC motors and are a cost effective option where increased dynamic performance and/or small size are important application factors. The low cogging design uses very thin and lightweight neodymium magnets with high density windings and a 6-slot core for smooth motion and an excellent torque to inertia ratio.

Baldor has published a highly informative brochure detailing the extensive range of motors that it produces for nuclear applications. The product line is the largest available from a single source and encompasses over 250,000 ratings, types, styles and sizes, from 200 W to 11,000 kW. The brochure is a key information resource for anyone seeking to install or replace a motor in a nuclear power plant, or in a nuclear fuel reprocessing or radioactive waste management facility. Typical uses include driving fans, pumps, compressors and motorized valve actuators.
