New BLF Brushless DC Motor System

Oriental Motor USA Corp. introduces the new BLF series brushless DC motor system that adopts a brand new design for its motor, gearhead, and driver. High performance speed control is achieved with an increased speed range of 80 to 4,000 rpm (50:1). In addition, the new BLF series is IP65 rated providing splash and dust protection.

The BLF series driver introduces a detachable digital operator unit that serves both as a data input unit and a digital display that can be used up to 16.4 ft (5m) away from the installed driver. The user can program 8 separate speed levels. Each speed can be set in units of 1 rev. per minute with separate acceleration and deceleration values. Detection of various motor and driver error functions including overload, overvoltage, low-voltage, missing phase, overspeed, overcurrent, etc., will immediately stop the motor and output an alarm signal.

The Oriental BLF series driver utilizes 3 speed display modes to help the user. The display modes include motor spe…

Programmable Pressure Sensors

TURCK USA introduces new programmable pressure sensors that combine high accuracy and performance with simple programming, resulting in an extremely user-friendly sensor. The PS400 and PS500 sensors are easily programmed via three controls: two push buttons for scrolling through programming features and one recessed enter key. The menu is clear and concise to allow parameters such as set points, reset points, output functions, analog ranges, and a range of special options to be programmed with ease. The menu also includes an optional electronic lockout that disables the push buttons from functioning until the lockout is removed.

The high accuracy programmable pressure sensors are specified with a switch point accuracy of ≤+/- 0.5 percent, generally exceeding what is required by the machine engineering sector. The combination of high accuracy and flexible programming often allows a single sensor to replace several conventional sensors (with varying sensing ranges) resulting in a signif…

ABB Drives Promote Green Paper Making

Paper manufacturer UPM's plant at Shotton has achieved its goal of producing all its paper from recovered waste paper, rather than virgin wood, with the help of ABB variable speed drives. Known as the '100% Shotton' project, it has involved the building of a new recycled fibre plant, a sludge plant and modifications to Paper Machine 1 and Paper Machine 2. ABB General Purpose Drives are used mainly on pumps in the process, using variable speed to match pump speed to the production rate.

They are also used on chemical dosing pumps to accurately add chemicals to the pulp. Some conveyors on the process also use ABB variable speed drives. The drives help control the process better, adjusting the inputs to the plant to maintain the correct pressure and temperature conditions. The drives also make it easier to control the production rate. Additionally, they contribute to energy savings by reducing the power drawn.

SolaHD IP67 Rated Power Supplies Eliminate Need for Enclosures in Extreme Industrial Environments

With the increasing demand for machine device control and communication over industrial Ethernet, DeviceNet, and other networks, OEMs have found that installing traditional power supplies in distributed and remote locations has become prohibitively complex and costly because of the need for protective enclosures, fans, and excess wiring. In addition, enclosures introduce another potential point of failure into the production line.

To reduce cost and complications, SolaHD has launched its new IP67 SCP-X self-sealed power supplies. They mount directly on machines or as freestanding components on a production line, removing the constraints imposed by power supplies that must be housed in enclosures. Compared to power supplies housed in a separate enclosure, the IP67 SCP-X reduces total cost of ownership by as much as 54 percent.

Because the IP67 SCP-X is available in 100 watt and dual 100 watt models, it has the versatility to power from one to four loads. The 100 watt model has a singl…
