Pole-changing DR.. series AC motors (2 speeds)

The simple way of controlling machine and plant speeds economically: 2-speed motors. We offer pole-changing DR.. series AC motors with a power combination from 0.15 kW / 0.20 kW to 18 kW / 34 kW. With this large selection, you are sure to find the suitable motor for your application.

We supply pole-changing 2-speed AC motors in sizes and designs DR63 and DRS.. as 4/2 and 8/4-pole motors with speeds in a ratio of 1:2 and as 8/2-pole motors with speeds in a ratio of 1:4 (DRS.. only).

These motors also come from our modular system – take advantage of its benefits: for example, we offer pole-changing AC motors for countries with a 50 Hz or 60 Hz line frequency, with the required voltage of course. Our pole-changing motors naturally come with all the certifications required by international regulations, so you can use them anywhere in the world, for example in Canada (CAS certification), the USA (UR certification) or in China (CCC certification).

We also offer a wide range of additional features so that you can find the perfect drives to match your applications. For example, with three different brake sizes for each motor frame size, you can size the brake to ensure that braking brings the drive to a halt safely and only as fast as necessary.

Our range of pole-changing AC motors mean that you can save time and optimize your motor selection, ordering and delivery processes. As a Global Player, we offer you this range of products in 48 countries around the world.

Only half the solution without a gear unit? Then you can use our modular system to combine our DR63 and DRS.. series 2-speed pole-changing AC motors with a helical, parallel shaft, worm, bevel or SPIROPLAN® gear unit of your choice. All these gear unit types are already available serially, combined as standard gearmotors.

 

 

Your benefits

2 speeds in one motor,

allow you to reduce the motion sequences in plants and machines with two or four times the motor speed.

Areas of operation

Example 1:
To limit the mechanical load during startup, the low speed is used and then quickly switched to the high operating speed without stopping. Just before the target, the system initially switches to the lower speed to avoid missing the target position, then the drive is switched off and, in many cases, brought to a complete standstill by a brake (rapid/creep speed positioning). This type of application is used in the horizontal drives and hoists of cranes, for example.
Example 2:
Continually transporting materials in just one direction results in very different load conditions for the drive's two directions of rotation. To optimize the time the no-load return travel takes, the system switches to the higher speed and returns to the start point. This type of application is used in inclined conveyors for building materials, bulk material, etc., or cable cars and rotary tables.
Example 3:
Stepped speeds are used to handle highly variable amounts of transport goods to reduce the strain on machinery and system components. This type of application is used in conveyor belts for building materials, bulk material, packages, etc.

 

 

 

 

DR...J variant synchronous motors (LSPM technology)
Are you looking for a motor with the highest level of energy efficiency and a compact design? In that case, the DR...J motor with LSPM technology might be of interest to you: one motor which covers three efficiency classes. IE2, IE3 and IE4.

The Line Start Permanent Magnet (LSPM) motor is an AC asynchronous motor which contains additional permanent magnets in the rotor with a squirrel cage. After an asynchronous start, the motor synchronizes with the operating frequency and runs in synchronous mode. A motor technology which opens up new, flexible possible applications for you in drive technology.

The synchronous motors do not show any rotor losses in operation.They have an impressive degree of efficiency while maintaining a very compact design. In the same efficiency class, a DR..J motor with LSPM technology is two frame sizes smaller than a standard motor of the same power rating.

Comparison example:

A standard DRE.. motor with 1.1 kW power rating of size 90 M meets the requirements of energy efficiency class IE2. By contrast, thanks to LSMP technology, you now use “only” one DRE..J of the smaller size 80S for IE2. Efficient and profitable!

With the DR...J motors (LSPM technology), we, as a motor manufacturer, have succeeded in combining the advantages of the durable and robust asynchronous motor with those of the low-loss, compact synchronous motor. For greater efficiency in your applications.

Only half the solution without a gear unit? In that case, use our modular system and combine an LSPM motor with a helical, parallel shaft, worm, bevel gear or SPIROPLAN® gear unit of your choice. All of these gear unit types are already available off-the-shelf, combined with DR...J motors as gearmotors.

And we do of course provide the right inverter technology for the controller and control. We develop and produce the drive electronics ourselves so that they are perfectly tailored to our motors and gearmotors and to your application.

 

 

Your benefits

 

Extend energy efficiency

as you can use the DR...J synchronous motors anywhere in the world, also in the highest efficiency class IE4.

Reduce size

as a DR...J motor can be up to two sizes smaller than a comparable standard asynchronous motor.

Constant speed

as the DR..J motor runs at a constant speed regardless of the load, synchronous to the operating frequency without slip.

 

 

 

Technical data

 

Areas of application

Applications in continuous duty such as luggage conveyor belts in airport logistics or pump applications
Applications with high speed consistency such as spinning pump drives for material supply in textile machinery, roller drives in the glass industry or conveyor drives for coating processes
For the planning of new systems that require higher efficiencies, DR…J motors in IE4 with LSPM technology can, for example,

replace reluctance motors or
IE2 motors of the same size.

In applications in process technology, this motor with frequency inverters MOVITRAC® LTP B and MOVITRAC® B has proven to be extremely effective as a single or group drive
For applications in materials handling technology with decentralized installation, simply combine the DR...J motor with a MOVIMOT® and the associated wiring and communication options

DRK..series single-phase motors

The running capacitor integrated in the terminal box is the special feature of our DRK.. single-phase motor. This does not only make the motor especially compact, it also enables application areas up to degree of protection IP66.

The compact single-phase motor with built-in running capacitor

Be it in Europe and the USA or in Brazil: you can operate the DRK.. motors in many power supplies because they are available in 50 Hz or 60 Hz with 220 V or 230 V. In total, there are six sizes available in the power range of 0.18 kW to 1.1 kW.

If you do not require a high starting torque in your applications, e.g. for fans, pumps or compactors, we recommend the DRK.. with integrated running capacitor. The motor becomes more compact as the running capacitor is housed directly in the terminal box. This means that approx. 45% to 50% of the nominal torque is available for start-up.

With an additional start-up capacitor, the motor is suitable for screw conveyors and conveyor belts as well as for agitators and dosers. You can expect a torque of approx. 100% to 150% of the nominal torque.

It goes without saying that everything fits together for single-phase motors and you can use many additional features of the DR.. modular motor system.

Only half the solution without a gear unit? No problem at all as geared single-phase motors are assembled from an extensive modular concept just like gearmotors.

 

 

Your benefits

 

Compact installation possible

thanks to the running capacitor integrated directly in the terminal box.

Splash-water protected

for all applications which require a high degree of protection, even outdoors.
