Data Acquisition Card Offers 16-bit Resolution

Amplicon has introduced the PCI-9221 from Adlink, a combined multifunction data acquisition and motion control card. The PCI-9221 is able to sample analogue signals at up to 250kS/s, with a resolution of 16-bits. Along with the 16 single-ended or eight differential analogue input channels, the PCI-9221 has two analogue outputs which are suitable for generating DC voltage signals.

The feature of this board is the programmable digital I/O, which may be used in one of the following four modes; eight digital inputs and four digital outputs; two 32-bit counter/timers; two encoder inputs; and two PWM (pulse width modulation) outputs.

The Adlink PCI-9221 is the first DAQ card to combine data acquisition and motion control, providing an optimal combination of analogue and digital I/O with motion control capabilities for test and measurement system integrators and laboratories.

The PCI-9221 is supplied with drivers for VB, C/C++, Delphi, .Net, Matlab and LabView.

‘The combination of data acquisition and motion control for this price makes it really good value for our customers’ Darren Saxby, Senior Sales Engineer for Measurement and Control at Amplicon said.

LEESON IEC Metric Motors

Metric-Dimensioned, LEESON Electric AC Motors meeting North American performance standards, including 1.15 service factor and EPACT efficiencies. Motors have both B5 flange mounting and B3 base.

Typically used for replacement on machine tools, textile machinery and other equipment with metric dimensions but requiring the heavy-duty torque and performance characteristics of motors designed for use in North America.

IP55 weatherproof enclosures, 60/50 Hz interchangeability (60Hz 230/460V & 50Hz 200/400V), dual stamped nameplates, CE mark, and F3 conduit box location. Motors are available in one of two frame constructions: aluminum or cast iron. Aluminum frame models are designated with a 192000 series catalog number; cast iron models are 193000 series.

Motor Controller Energy Savings Tested

Power Efficiency Corporation has announced the results of tests of its new digital single-phase motor controller on two commonly used commercial electric motors. The test was conducted by Yahia Baghzouz, who is a Technical Advisor to Power Efficiency Corporation. Dr Baghzouz is a Professor of Electrical Engineering at the University of Nevada, Las Vegas and is the Co-Director of the UNLV centre for Energy Research.

The purpose of the test was to determine the energy savings achieved with Power Efficiency’s new digital single-phase motor controller prototype. Single-phase motors are typically found in residential and light commercial appliances, such as pool pumps, refrigerators, clothes dryers, heat pumps and other applications. Power Efficiency conducted this test in anticipation of efforts to enter co-development and sales arrangements with motor and appliance manufacturers.

‘We are very pleased with the results of the test conducted by Dr Bagzhouz’, said Steven Strasser, the company’s Chairman and CEO. ‘We are presently manufacturing a number of prototypes and are in discussions with several large motor and appliance manufacturers who are waiting to receive our prototype to commence their own testing and evaluation’. ‘If the evaluations by these potential customers are positive, we expect to enter co-development arrangements for including our controller as a standard component on motors in various applications’.

‘This market represents a significant revenue opportunity for the company because there are over a hundred million single-phase motors sold every year in the US’. ‘Furthermore, efficiency standards are becoming increasingly stringent for appliances and other equipment powered by single-phase motors’. ‘Our goal is to have the most cost-effective technology for appliance and motor manufacturers to meet these standards’. In a test on a 1/3 HP Emerson split-phase motor at 30% of full load, energy savings were 41% and at 50% of full load, energy savings were 24%. Testing on a 3/4 HP Baldor capacitor-start motor at 30% of full load, energy savings were 22% and at 50% of full load, energy savings were 8%.
