Packaging Stimulus
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.

Beyond the Quick Fix - Supply Chain Software
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.

Facing the Challenges of the Current Hybrid Electric Drivetrain
Presented is a high-phase, order-induction motor drive for use in a series hybrid architecture. This solution overcomes numerous compromises in current hybrid powertrain designs. Notably, it allows for a vehicle that is competitive in terms of performance and cost.

Lower-Loss Technology for a Stepping Motor
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.

Historic Danish Theatre Gets a Facelift
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.
