Brushed DC Motors

Brushed DC Motors (series G/GR)

Brushed DC motors from Dunkermotoren have a low cogging torque, bear robust construction and have low moments of inertia. Brushed DC motors can be combined with planetary gearboxes, worm gearboxes, brakes and encoders to provide a flexible, adaptable, market-oriented solution.

The Brushed DC motors are well-known for:

  • Longer life than commutated motors from other manufacturers
  • Low detent torques
  • High efficiency
  • High dynamic acceleration
  • Good regulation characteristics
  • High power density
  • Maintenance-free
  • Robust design
  • Low moment of inertia
  • Motor insulation class E
  • Winding insulation class F
  • Extremely high short time overload capacity of the motor
  • Surface protection
  • Minimum interference radiation, optional interference versions
  • Protection up to IP 65
  • High quality due to fully automated production lines

Planetary and Worm gearboxes (series PLG/SG)

Planetary and Worm gearboxes are developed by Dunkermotoren; produces transmissions that are characterized by their smoothness, compact design and excellent efficiency. The product range includes planetary and worm gears.

Worm gearboxes (SG) are well known 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 ensures a long service life at the rated torque. In quite 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.

Planetary gearboxes (PLG) are known to 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.

Controllers / Gateways (RS/BGE)

Controllers and Gateways belong to the category of motors and gearboxes. Control electronics and gateways are crafted with precision. These include electronics for speed control and positioning to integrated PLC functions. Field bus and Ethernet-based communication interfaces are integrated in the drive.

Brushless DC motors

Brushless DC motors offer high efficiency, great dynamics and high power density. Also worth mentioning are our BLDC motors with integrated power and logic electronics. Brushless DC motors are easily combined with planetary gearboxes, worm gearboxes, brakes and encoders.

The Dunkermotoren BG range of brushless, direct current motors (EC motors) are well known for:

  • Very long life
  • High efficiency
  • Highly dynamic acceleration
  • Good regulation characteristics
  • Wide speed range
  • High power density
  • Maintenance-free
  • Robust design
  • Integral Hall sensors for rotor position
  • Low moment of inertia
  • High degree of protection
  • Winding insulation - Class E or B
  • Neodymium magnets

AC Motor Manufacturer

AC motors from Dunker motors are characterized by robust construction and are maintenance free over its lifetime.

Special features include:

  • Solid, maintenance-free
  • Reversible
  • Insulation to VDE 0530, insulating class F
  • High degree of protection, IP 54
  • Terminal box cover, can be turned by 4 x 90°
  • Built-in fan tor optimum cooling

Servo components / brakes

Servo components: Dunkermotoren offer motors and transmissions as well as encoder systems. Optical and magnetic incremental encoders can be combined with the appropriate drives.

Linear Motor Systems

Linear motors or linear systems from Dunkermotoren offer highly dynamic motion and precise repeatability with or without external encoder feedback. These are available as actuators, motor components or easy-to-use modules with forces up to 1860N.
