SEW-Eurodrive introduces its new DR motor series, a modular system of motors with millions of drive combinations. Food, beverage, and water/wastewater users, for example, can specify coating and sealing variations that protect motors in wet environments and in a wide range of temperatures. Automotive manufacturers can choose among many connector options that save time and ensure accuracy in installation and replacement. A variety of sensor and feedback options for speed, position and even brake wear suit sophisticated electronic drive control systems found in packaging and logistics applications in many industries. Maintenance-friendly modular brakes, encoders and other options make retrofits and other field adjustments simple and fast in any market.
The DR motor meets and exceeds international energy standards and comes in three efficiency levels: DRS Standard Efficiency (IE1), DRE High Efficiency (IE2) and DRP Premium Efficiency (IE3), which meets EISA 2007 and NEMA Premium standards for the US, and other energy standards in Canada, Australia and New Zealand. Other customizable options include:
•with a manual brake release, automatic or lockable, that can be easily field-adjusted to one of four different mounting positions.
•mounted encoders are also available for high-precision applications.

The DR series "was developed with over 30 years of product knowledge from the DT/DV series and the latest in technology, materials and design," said Dave Ballard, manager of engineering and marketing. "For years, SEW-Eurodrive has provided the industry with highly efficient drives and gearmotors. Now, we provide optimal customization for cost savings, and deliver even better total drivetrain efficiency."
Rotor cage material is copper and aluminum. Horsepower breaks down as follows:
