DT/DV series AC motors and AC brakemotors are the ideal match for SEW-EURODRIVE standard gear units. Our wide range of variants ensures that we have the right motor for your application, whether 2-, 4-, 6- or 8-pole or multi-speed. SEW-EURODRIVE brakemotors have integrated DC safety disc brakes. The brake control is installed in the terminal box as standard, but is also available in control cabinet version as an option. The patented two-coil brake system facilitates high starting frequency and positioning accuracy with particularly short response and reaction times.

Proven in a great number of applications and offering a substantial number of additional features that have been added over the years, this motor series can not only be used as IEC standalone motor with feet and/or flanges but is also ideally suited for direct mounting to the standard helical, Parallel Shaft Helical, Helical-Bevel, Helical-Worm, and SPIROPLAN Gear Units. The energy efficient motors of the DTE/DVE type are the first motors in the modular system worldwide that have been using copper diecasting technology for the rotor cage since 2002.

The beverage and food industry and the chemical and pharmaceutical industry place high hygiene demands on production facilities. The drive solutions used in the past made it very difficult to clean the production systems as thoroughly as required. Standard motors often come equipped with cooling fins and fans in which dirt can accumulate and germs and bacteria may be distributed in air swirls. SEW Eurodrive ASEPTIC motors of the DAS series have a smooth surface and are not equipped with fans.

Surprisingly few mechanical engineers and operators know that over 95 % of a motor's life cycle costs are energy costs. This is why only few plants are fitted with energy efficient motors. SEW-EURODRIVE is the first company in the world to implement copper die-casting technology in industrial series production successfully since 2002. Result: Highly energy efficient motors at a surprisingly competitive price that comply with all applicable European and international standards. DTE and DVE series 4-pole motors surpass the EFF1 limit value.

SEW-EURODRIVE offers various optional protective measures for operation of motors and gearmotors under special ambient conditions. We provide KS corrosion protection and OS surface protection. Optimum protection for motors is offered by a combination of corrosion and surface protection. KS corrosion protection for motors comprises the following measures:

• All retaining screws that are loosened during operation are made of stainless steel.
• The nameplates are made of stainless steel. Various motor parts are coated with a top coat.
• Flange contact surfaces and shaft ends are treated with a temporary anti-corrosion agent.
• Additional measures for brake motors.

In addition to standard surface protection, motors and gear units also have the option of surface protection OS1 to OS4. We can also carry out special procedure Z in addition to OS1 to OS4. Special procedure Z means that large surface recesses are sprayed with a rubber filling prior to coating.

On request, SEW-EURODRIVE motors and gearmotors can be supplied with an integrated mechanical brake. The brake is an electromagnetic disc brake with a DC coil that opens electrically and brakes using spring force. The brake is applied in a power failure, making it compliant with fundamental safety requirements. The brake can also be released mechanically if equipped with a manual brake release. Either a hand lever or a setscrew is supplied with the brake for this purpose. The hand lever springs back automatically, and the setscrew is lockable. The brake is activated by a brake control system accommodated either in the wiring space of the motor or in the control cabinet.

The new modular system of asynchronous AC motors from SEW-EURODRIVE is a development based on the established motor series. The new DR series AC motors combine the entire range of required motor efficiency levels as well as energy efficient motors making it a future-proof innovation of the highest quality. In the development of energy efficient motors, SEW-EURODRIVE became the first company in the world to succeed in using die-cast copper technology in industrial high-volume series production in 2002.

The modular DR motor system from SEW-EURODRIVE offers three different brake sizes per motor size and As Cost-Optimized Rotary Position Sensors Integrated In The Motor. All other additional features of the new DR series are available in all energy efficiency levels. The DR motor supports any energy efficiency standard worldwide and even already meets the upcoming IEC standard. They bring a whole range of unique benefits to planners and users.

In an AC motor, electrical energy can never be converted into mechanical energy without any losses. The goal of many international regulations, directives and standards is to reduce these losses. The two parts of the motor standard IEC 60034, part 2-1 and part 30, will provide an internationally uniform and accepted procedure for determining and classifying the level of efficiency of asynchronous AC motors. The diversity (former part 2 of IEC 60034, IEC 61972 or IEEE 112) will then be a thing of the past and manufacturers as well as users can be on the safe side. DR motor types DRS, DRE and DRP surpass the required levels of efficiency and belong to classes IE1, IE2 and IE3.

SEW Eurodrive BE brake is based on the extremely successful BM(G) brake, but was further developed in many aspects. The brake size has so far been unalterably linked to the motor size. "Less" brake is only possible by reducing the braking torque with a modified brake spring. The new combination options of DR motors with BE brakes are no longer subject to this unalterability. The DR motor can be combined with two or three different BE brake sizes. Depending on the braking torque or braking work required, the DR motor can be combined with the ideal BE brake.

Brake mounting to motors size 90 and larger offers another special feature. The brake itself is mounted on a friction plate, which only has to be attached to the endshield. Without opening the motor, the unit can now be demounted and replaced - also by a larger or smaller brake.

The new built-in encoders are unique in the modular DR motor system. Instead of an external encoder mounted to the fan guard of the non-drive end, the encoder can now be installed between the endshield and the fan. This means that any extra length caused by mounted encoders is avoided. 3 variants are available:

• HTL signals in A+B tracks (+ negated)
• Sin/cos signals in A+B tracks (+ negated)
• Signals of the rotation counter as absolute value
