Modular motors cover all the bases

Modular motors cover all the bases
One option for saving energy is to operate electric motors exclusively with frequency inverters in a controlled fashion. But even the electric motor itself can make a significant contribution to reduced energy consumption. Five years ago SEW Eurodrive was the first to introduce energy efficient motors based on die-cast copper technology.

Another trend seems to be driven by the requirements of the logistics industry: the demand for small, compact and decentralised drive solutions for use in handling and transportation systems. SEW Eurodrive has taken these and other trends on board, and has come up the new modular DR motor system in response, which the company reckons will set a new standard in drive engineering. The DR motor already meets future demands for the efficiency ratings of asynchronous motors. It integrates all current requirements regarding efficiency worldwide (standard, high and premium). The motors are optionally available with rotors featuring a second-generation copper cage.

A new modular brake design offers the choice of two or three brake sizes for each motor. Brake motors with inverter control require less braking action and therefore lower braking torques are required for energy efficient motors. It is also a lot simpler to install or remove BE generation brakes on size 90 DR motors. These BE brakes are mounted on a friction plate and can be easily removed.
