Now more than ever, manufacturing companies are examining what steps need to be taken to ensure improvements to machine reliability by predicting system failures and minimizing downtime.
The recent trend toward using segmented laminations as a means to increase slot fill and facilitate automated fabrication of electric machines comes with a penalty of increased core loss at the segment joints.
This case study presents how electronics and software can be applied to a mobile hydraulic application, as well as how electro-hydraulics have evolved over time.
The demand for stepping motors with high efficiency and low losses has been increasing, although the demand had been previously focused on high torque. Also, the selection of the most suitable grade of lamination for improvement in fastening of the laminated cores has reduced losses significantly at their peak, when compared to conventional stepping motors. Lowering the losses of the motor has enabled continuous operation that was previously impossible. An expansion of the stepping motor’s usage into applications where another motor has been used for continuous operation and other uses—due to the
heat generation problem—can now be pursued. In addition, these motors are very effective for energy saving. This paper explains the technology used for lowering the iron losses of the stepping motor.
The Royal Danish Theatre has occupied
the heart of Copenhagen for centuries
and recently upgraded to a new control system featuring Sprint Electric DC drives to extend the lives of the existing motors, keeping replacement costs down. The Swedish stage design and technology company Visual Act retained most of the original motors and mechanics while providing a much-needed facelift to the stage.
In order for a company to be as efficient as possible, production, inventory and distribution components must be a top priority. A focused supply chain that gets the right materials to the right places in the allotted time frame encourages repeat business. These are concepts somewhat overlooked by many business executives in today’s economy.
Few industries are experiencing change quite as fast as the packaging arena. Lighter-weight containers are being
introduced to reduce costs and energy use, packaging is being redesigned to attract consumer attention and manufacturers are using fewer materials in an effort to address environmental concerns.
