If you’re not familiar with the motor and drive industry, controlling a motor can be intimidating. Technology offers us many solutions when controlling motors and electronics, but not all of those solutions are equal. There are a number of different ways you can control how a motor starts and stops, and it all begins with […]
D&D Engineering (Hull) Ltd is a manufacturer of conveyors and product handling equipment. Eighty percent of its customers are in the food industry, mainly in the prepared produce sector, with some involved in the production of chilled products and bakery goods. One of D&D Engineering’s recent customers is John Baarda Ltd, a company specializing in the growing of tomatoes. John Baarda Ltd […]
Today industry and commerce are facing an energy challenge. Pressures to reduce energy consumption, lower carbon dioxide emissions and provide secure power supplies are coming from governments, consumers, legislators and shareholders alike. All of these pressures are against a background of ever-rising energy prices and the dramatic effects climate change is having on the environment. As […]
AC electric motors operate by applying alternating current (AC) power to the electric motor. The main parts of AC electric motors are the stator and rotor. The AC electric motors’ stator consists of coils that are supplied with alternating current power and produce a rotating magnetic field. AC electric motors rotor will rotate inside the […]
The mining industry is challenging, and ABB operates accordingly to the highest standard of occupational health and safety excellence and remains constantly vigilant in carrying out its duty of care. ABB’s combined efforts and commitment allows it to achieve a continuing improvement in its safety record. The machines and equipment used in mining must provide […]
In the past, applications operating at less than 300 rpm, and rated from 500 kW to 5000 kW, have been controlled using a medium-voltage constant speed synchronous motors. Common applications include crushers and various mills used in metals, cement or mining. Replacing a constant speed with variable speed drive control brings substantial operating and maintenance improvements. Variable-speed drives provide soft starting, […]
Today, VFD machine safety technology is making the previously-complicated job of implementing a machine safety system much easier. Recent technical advances make safer operation less complex, while at the same time offering new potential for productivity. New developments in drive-based functional safety contribute to greater overall protection of people, machines and ecosystems. The aim is […]
Variable speed drives have over the past decade allowed to become a cost efficient way to reduce power costs and increase system efficiency. Today manufacturers around the globe within a wide range of industries are finding more ways to apply drives to their rotating equipment. From past experience, smaller horsepower drives typically fail in eight years […]
Alternating current VFD drive technology extends the motor speed range from zero to high above the rated speed of an electric motor, increasing the productivity of the driven process. When a low capacity is enough, the vfd reduces the machine speed and saves energy. VFD equipment all over the world save energy in applications for pumps, fans, […]
Permanent magnet servo motors are also known as brushless servo motors and/or PM (permanent magnet) servo motors. Permanent magnet servo motors are used when an industrial application requires high performance and precise speed regulation. Permanent magnet servo motors are manufactured with a designated controller known as a servo drive or servo driver. Permanent magnet servo […]
Eaton VFD repair is an asset to Sullair service centers because Eaton VFD replacement is expensive and long lead times for Eaton drives are a common problem. Sullair service centers often send their Eaton VFD repair to Precision Electric to increase production in the plant. Precision Electric service technicians have hundreds of years combined experience in bench testing […]
What is a variable frequency drive? Variable frequency drives are also known as variable speed drives, VFD’s, adjustable speed drives, and inverters. Variable frequency drives are solid state motor control systems designed to control the speed of an AC (alternating current) electric motor. Variable frequency drives operate as load controls within AC electric motor applications; and […]
