ABB
ABB ACH550 base drives, E-Clipse bypass units, and drives with input disconnects are now International Building Code (IBC) seismic-compliance certified. The certificate of compliance qualifies the products for use in applications and buildings in which IBC requires that seismically rated equipment be considered. While principal applications for IBC-certified drives include disaster-prone areas of North America, design parameters recommended by IBC could affect a number of facilities in public and private sectors, such as commercial office buildings, hospitals/health-care facilities, schools and education buildings, manufacturing facilities, and water/wastewater operations.

Baldor
Combining a laminated finned-frame RPM alternating-current motor with a permanent-magnet salient-pole-rotor design, the VS1 cooling-tower drive can replace the right-angle gearbox and jackshaft in many cooling towers. Controlled by the cooling-tower drive, a fan couples directly to the motor shaft to provide variable-speed performance, quiet operation, and reduced energy consumption.

LCR Electronics
LCR Electronics, a leading manufacturer of EMI filters, electronic products, as well as high-end enclosures for military, telecom, and commercial applications, now offers two new digital PWM (pulse-width modulation) motor controls. The controls — available in battery-powered and AC-line powered versions — incorporate H-bridge circuitry with high-speed switching to produce precise speed and torque control, bi-directional operation and overload protection.

The high voltage EC104 and the low voltage EC106, with control methods for either two or four quadrant operation, are adaptable to many different DC brush, shaded pole and PSC motor applications including appliances, pumps, compressors, blowers, conveyors, and traction systems.

McQuay
By optimizing HVAC-system performance, variable-frequency drives (VFDs) from McQuay can save up to 30% in energy costs and have a payback of four months. The VFDs can be added to motor and pump applications to reduce energy costs during low-demand periods.

Parker
According to company sources, iSpeed inverters can save up to 40% of energy usage in refrigeration systems using single-compressor installations and up to 25% with conventional multistage compressor racks. The inverters keep lead compressors running smoothly, and proprietary software limits cycling of the fixed-speed compressors. Compressor wear is reduced on all compressors, minimizing electrical costs and stresses to the electrical infrastructure.

Siemens
Designed for HVAC applications, SED2 variable-frequency drives (VFDs) support a variety of digital and analog input/output for diverse control capability. Built-in proportional-integral-derivative features control pumps and fans, and an integral system protocol can interface P1/N2 networks. Using the VFDs’ multilevel parameter access, operators can pinpoint relevant data quickly. A low-harmonics design reduces noise and interference, eliminating the need for filters/reactors in most installations.
