A Variable Frequency Drive regulates the speed of a 3-phase AC electric motor by controlling the frequency and voltage of the power it delivers to the motor. Today, these devices are becoming prevalent in a wide range of applications throughout the industry, from motion control applications to ventilation systems and many others.

Courses cover PLCs, electrical controls and instrument maintenance.

F800 Series is designed to efficiently move air in HVAC applications, including air handlers, cooling towers, and pumps.

IndustrialTuff Variable Frequency Drive (VFD) Cables, designed to carry power from AC drive systems to AC motors, now includes four new 10 to 16 AWG, 600V UL 1277 cables incorporating a signal pair for brake applications. The cables feature an overall Beldfoil shield plus 85 percent TC braid shield for highly effective radiated and conducted noise protection.

ACH580 VFDs are integrated with ABB Ability monitoring services – ABB’s cross-industry, digital offering, which provides real-time data about drive status and performance from any location. Monitoring parameters include drives availability, environmental conditions and fault events.

HANNOVER MESSE 2012, which runs from 23 to 27 April, provides an overview of all key resource-saving industrial technologies.

Distributing water on a large scale has been a challenge that the world has tackled for decades. It is a particular challenge in high-rise buildings, and with a trend for designers to build up in urban areas, rather than out, it is a challenge that has become a new focus for design engineers.

E-Clipse Bypass lets HVAC drives communicate directly with Building Automation Systems.

ISA Training and Education in July: Learn, Advance, Succeed

To achieve a successful industrial automation project implementation, it’s important for everyone to be involved with the process.

Flexium+ comes with NUMSafe, which uses a Fail Safe over EtherCAT (FSoE) protocol to ensure integrity of all safety-related data.

Danfoss is doubling its Loves Park, IL, facility that produces variable frequency drives, adding both production and office space.

As part of a larger infrastructure investment, CP Automation recently installed a Riello 3/1 phase UPS system at 40 kVa at one bustling UK port to improve the duration of its power supply.

Offered in aluminum and cast iron frame configurations, these motors include high efficiency and industry-leading NEMA PremiumR efficient designs to help motor users lower energy costs and extend service life. A unique die cast copper rotor and special stator designs provide the added efficiency of these motors.

To maintain a constant (rated) flux density, the applied voltage must also be changed in the same proportion as the frequency (per Faraday’s law).

The volts per hertz ratio (V/Hz) controls the torque of a motor. As long as this ratio is in proportion with the nameplate rating, the motor will develop rated torque.
