The motors are solidly designed and are maintenance-free for life. The multi-grooved stator contains a threefold winding which, together with the phase-shifting capacitor (series KD), creates a symmetrical rotating field at the rated working point of the motor. The rotor is of the squirrel-cage type. Two design diameters and a variety of design lengths provide rated torques from 0.75 to 31.5 Ncm in double-pole or four-pole versions.

The DC venetian blind drives are particularly designed for the use in interior blind applications.
DC Drives for interior blinds:
The Venetian Blind Drives series DCD22 - based on direct-current technology - are particularly designed for the use in interior blind applications.
DCD22-2-G:
Double shaft drive with integrated incremental encoder. The signals can be interpreted by the use of an external controller and used for end position and velocity control. The upper end position is limited by an external end switch (push-button).
DCD-22-2-E:
Double shaft drive with integrated controller. The integrated electronics controls upper / lower end position and velocity. The drive is connected to the power supply via an up / down push-button.
Dunkermotoren's planetary gearboxes are notable for very compact design, low weight and excellent efficiency.
Dunkermotoren develops and produces transmissions that are characterized by their smoothness, compact design and excellent efficiency.
Planetary gearboxes (PLG) have the highest continuous torque capacity of all types of gearbox; at the same time they have a very compact form, low weight, and excellent efficiency. Self-centering planet gears ensure a symmetrical force distribution. The ring gear also forms the housing of the gearbox. The gearbox output shaft is supported in two ball bearings so that it can withstand high axial and radial loads. The gearboxes are customized, e.g. for use in especially low ambient temperatures, or as high-power gearboxes with reinforced output shafts, or with special lubricants for very long service life.
Dunkermotoren's worm gearboxes are notable for very compact design, low weight and excellent efficiency.
Dunkermotoren develops and manufactures gearboxes, which are notable for very compact design, low weight and excellent efficiency.
Worm gearboxes (SG) are noted for their very quiet running. The worm-gear shaft has bearings on both sides. The gear components, made of bronze or steel, and the lubrication ensure a long service life at the rated torque. In many applications, the location of the output shaft at 90° to the motor shaft provides an optimum design solution. On request, worm-gearboxes can be supplied with a hollow output shaft.
Dunkermotoren's SpiroTec gearboxes are notable for very compact design, low weight and excellent efficiency.
Dunkermotoren develops and manufactures gearboxes, which are notable for very compact design, low weight and excellent efficiency.
Spiro Tec Gearboxes (STG) are gearboxes with right-angled output. The core of this product line is the spiral toothed gear set. This set makes it possible to responsibly transfer high torques with small axle distance in very little space. Both toothing parts are made out of hardened steel, so the gearbox works wear-free. That’s the reason why not only the toothing parts have got a very high lifetime, but also the lubricant stays free from contamination that again means a protection of the drive shaft. The housing is conducted in monoblock-design which leads to a very high precision of the gear meshing and an improved rigidity of the drive system. Impressive is the smooth running of the Spiro Tec gearbox that reaches the level of worm gearboxes.
Bevel gearboxes are characterized by a right-angled output without any axle offset. They are recommended for particularly low installation conditions, as the gearboxes are arranged centrically to the motor. Their efficiency is high and they can be driven back, which is required for door drives, for example. In order to bring the reduction ratio into a suitable range, one or two planetary stages are connected upstream of the actual bevel gear stage.
Dunkermotoren offer motors and gearboxes as well as control electronics and gateways.
Dunkermotoren offer motors and gearboxes as well as control electronics and gateways. These include electronics for speed control and positioning to integrated PLC functions. Fieldbus and Ethernet-based communication interfaces are integrated in the drive.
Motors in the BG, GR/G and KD/DR range can be fitted with rotor brakes. As standard, power-off brakes are employed, i.e. the brake operates when no voltage is applied and releases when current flows. Power-on brakes are available on request. IP 54 covers are available for all brakes. Combinations of incremental encoders and brakes are possible. Depending on the motor-brake combination, degrees of protection up to IP 65 are possible. To protect the DC contacts in your control system against arcing, we recommend the use of a freewheeling diode.

The magnetic pulse generators are applicable for speed detection, speed control and positioning.
The magnetic pulse generators are applicable for speed detection, speed control and positioning in combination with corresponding
electronics.
The magnetic pulse generators are connected mechanically to the motor and transmit a series of impulses corresponding to the motor speed and direction via external leeds.
The non-contact magnetic generator is equipped with hall sensors and magnet ring and is wearfree. A safe operation is possible due to the simple design, the magnetic signal activation and the starting signal which can be varied by the supply voltage.
Most magnetic pulse generators are available on request with protection cover IP 54.
Digital incremental encoders for stringent demands on the quality of regulation and positioning accuracy.
Where stringent demands are placed on the quality of regulation and positioning accuracy, the DC motors are available with a digital
incremental encoder.
Incremental encoders have no sliding contacts and are not subject to wear. A light-emitting diode, a slotted metal disc, and a photo-diode array form a photoelectric circuit. An internal logic produces two squarewave signals phased at 90° to each other from the output of the photodiodes, with or without a reference impulse.
Where the cable length between the encoder and controller or between the motor and encoder is more than 2.5 m, we recommend use of the RE .. TI, fitted with an additional power booster. The standard supply voltage for the incremental encoder is 5 VDC. As specials, 24V versions are also available. An IP54 cover is recommended as protection against external influences. In combination with motor BG 65, the incremental encoder can be incorporated in the IP65 extruded motor body. For the motors BG 45 | BG 75 an integral magnetic resistive incremental encoder is available (ME integrated).
