EC: DR Motor
Motion Control - motors: SEW-Eurodrive Inc., DR Motor. SEW-Eurodrive's new modular DR motor system offers more efficiency, performance and pricing options for gearmotors or stand-alone models. This is a Control Engineering 2011 Engineers' Choice (EC) Award winner.
The modular DR motor is well suited for most any industry. It allows users to specify exactly those options needed for any given application. Users in food, beverage, water and wastewater will find that the coating and sealing options protect these motors in wet environments in a wide range of temperatures. Automotive manufacturers rely on the many connector options to 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 found in packaging and logistics applications. Maintenance-friendly modular brakes, encoders and other options make retrofits and other field adjustments simple and fast.
The DR motor offers choices in efficiency levels to meet US and overseas standards. For instance, the DRP Premium Efficiency model meets EISA 2007 and NEMA Premium standards for the USA as well as other energy standards in Canada, Europe, Australia and more. In addition to energy efficiency options, the DR motor also offers other customizable options, including brake size, cost-optimized encoders and mounting type.
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.
Encoders: 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: The motor can be supplied as a gearmotor, foot-mounted and/or flange-mounted with numerous through-hole or tapped-hole configurations. A NEMA C-face flange is also available.
