Motors and Drives
When steppers or induction motors are not enough
K
ollmorgen has launched the VLM servomotor series to
fill the gap between stepper and high-performance servo motors. The new VLM series synchronous servo motors offer OEMs, machine builders and end users, an excellent price- performance proposition in the torque range of 0.5 to 4.5Nm continuous and 16Nm peak, with speeds of up to 6000rpm. They also provide highly flexible configuration, proven quality and high reliability.
Hence, they are a very useful solution for many applications where stepper or asynchronous motors are pushed to their limits but the
expense and unused dynamics of high performance servo motors is not desirable. The many standard design
and configuration options built into the range allow engineers an optimal solution from the outset, to tailor their applications and machine requirements. Thus, installation time and cost is minimised and the price-performance ratio is further improved. The VLM series motors are available with standard frame sizes of 60mm and 90mm or NEMA 23 and 34 in each of the six most popular motor sizes and with a choice of 12 standard windings. ●

Boost to electric drives market in Eastern Europe, Russia and CIS
T
he demand for industrial automation, rising energy costs and improved understanding of the advantages of electric drives will encourage their uptake across Eastern Europe, Russia and CIS over 2012-2016. New analysis from Frost & Sullivan, Electric Drives in
Eastern Europe, Russia and CIS Market, finds that the market earned revenues of $472.5 million in 2011 and estimates this to reach $652.1 million in 2016.
The research covers alternative current (AC), direct current
(DC) and servo drives. AC drives are the largest product segment in the market
“Industrial automation helps optimise manufacturing processes, improve plant performance and reduce operational costs,” explained Frost & Sullivan Industrial Automation & Process Control (IPC) Research Analyst Maryna Osipova. “AC drives and servo drives are key components of advanced machines that help end users achieve such goals and sustain competitiveness on a global scale.” Servo drives and AC drives maximise the cost-efficiency of production and reduce the operating costs of industrial processes. These types of drives are used in different frequency applications, and demonstrate superior energy performance.
Rising energy costs too are pressuring end users to
enhance their energy-efficiency. This is training the spotlight on electric drives that support better energy performance. “In eastern Europe, electric drives are perceived as one of the best methods to save energy,” explained Osipova. “The use of advanced electric drives has the potential to reduce energy consumption by 25 to 50 per cent.” However, the high corruption index of CIS countries and Russia and the limited development of the private sector are impeding market development. Moreover, economic and political instability dampen the level of government and foreign investments. “To successfully confront these challenges and limit the risks of establishing business in these regions, electric drives suppliers need to have a comprehensive understanding of the prevailing micro-environment,” said Osipova. Meanwhile, with the introduction of stringent safety requirements in developed countries, demand for machine safety solutions is expected to rise significantly. The growth of manufacturing sectors in emerging countries fuels further adoption. Manufacturers world-wide recognise that machine safety can give them a competitive advantage and a good public image, and therefore, opt for machine safety systems despite the economic downturn. Frost & Sullivan says the Strategic Analysis of Global Machine Safety Market earned revenues of over $1.27 billion in 2011 and estimates this to reach $1.75 billion in 2016. ●
