SEW-Eurodrive Launches Energy-Efficient DR Motor Series
SEW-Eurodrive, a leading global supplier of innovative drive automation solutions, announces the release of the new DR motor modular system, offering customers a single series with millions of drive combinations.
Available February 1, 2010, the modular DR motor is well suited for most any industry. The modular system allows users to specify exactly those options needed for any given application. The coating and sealing options keep these motors protected in wet environments in a wide range of temperatures. The many connector options save time and ensure accuracy in installation and replacement. The variety of sensor and feedback options for speed, position and even brake wear are perfect for sophisticated electronic drive control systems. 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 USA and other energy standards in Canada, Australia and New Zealand. In addition to energy efficiency options, the DR motor also offers other customizable options, including brake size, cost-optimized encoders, and mounting type.
“A truly innovative motor, the new 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, with the addition of the DR motor series, we provide optimal customization for cost savings and deliver even better total drivetrain efficiency.”
Providing simple configuration and ordering, the DR motor saves space and costs due to its compact design and also promotes an extended life from an environmental and regulatory perspective.
Customizable Options
Brakes: Inverter driven motors often don’t require large brakes. To take advantage of this, up to three brake size options are available for each motor size. The ability to specify the brake size ultimately results in greater cost savings for the customer. Additionally, the series is equipped with a manual brake release, automatic or lockable, that can be easily field-adjusted to one of four different mounting positions.
Encoder: The new built-in encoder is fully integrated into the motor, making it more compact and less expensive. The encoder is installed between the endshield and the fan and is connected at the terminal box, so it can be easily retrofitted. Traditional HTL, sin/cos, or absolute mounted encoders are also available for high-precision applications.
Mounting: Now offering new mounting capabilities, the motor can be foot-mounted and/or flange-mounted with numerous through-hole or tapped-hole configurations. A NEMA C-face flange is also available.
