Disc Motors

Baumüller disc motors

The main strengths of Baumüller disc motors are that they are compact and flat. In their shortest design, only 36.5 mm of axial space is required.

 

 

GDM DC disc motors

Baumüller DC disc motors are permanent magnet motors with ironless rotors and barrel commutators, meaning that they are low in inertia and highly dynamic throughout the whole speed range.

 

DSM brushless disc motors

For applications where DC motors (with their associated commutator and carbon brushes) are unsuitable, brushless disc motors are ideal. The additional electrical control required for any special applications can also be incorporated in the motor housing.

 

GDM 75 - 12 - DC Disc Motors

 

  • Compact, flat design
  • Low in inertia and highly dynamic throughout the whole speed range
  • Precise true run even at minimum speeds
  • Can be overloaded to several times its rated value for a brief period
  • Minimal wear of carbon brushes, meaning that maintenance costs can be reduced
  • Very well suited to high-speed start/stop operation
  • For low powers up to 150 W
  • Permanently excited DC motors with ironless rotors
  • Available with tachogenerator, pulse encoder, holding brake, and gearbox as options
  • Insulation class F, type of protection IP44 (higher types available on request)
  • For low and medium powers up to 4500 W

GDM 100 - 250 - DC Disc Motors

  • Barrel commutator
  • Ironless rotor
  • Winding as a wire bobbin
  • Given sufficient ventilation, and depending on the type of winding, these motors are able to provide peak powers well in excess of their nominal ratings; even capable of offering full nominal torques at standstill without sustaining thermal damage
  • The inductance of the armatures is very low, which is the reason for minimal wear of carbon brushes. Therefore maintenance costs can be substantially reduced.
  • All of the GDM range permit a high dynamic performance throughout the whole speed range. Therefore, they are very well suited to high transient loadings i. e. frequent start/stop running modes
  • Speed-regulated motor without any externally mounted electronics
  • Reduction in cost of cabling
  • No additional installation of sensor mechanisms, such as tachogenerators or impulse transmitters/encoders
  • Maintenance-free due to brushless electronic commutation
  • Flat construction
  • For low and medium powers up to 4500 W

DSM 115 - 190 - Brushless Disc Motors

  • Very quiet
  • Almost no indexing torque
  • Low in inertia and highly dynamic throughout the whole speed range
  • Compact, flat design
  • Low maintenance costs
  • Special design as high-torque drive
  • Power can be doubled by means of a second stator
  • For low and medium powers up to 6300 W
  • Available with pulse encoder, resolver, sincos encoder, holding brake, and gearbox as options
  • Insulation class F, type of protection IP44 (higher types available on request)

 

Brushless disc motors are manufactured according to two different principles:

For the lower power range (DSM 115 series), the principle of the DC disc motor is reversed. The ironless winding slips from the rotor into the stator and the magnets slip from the stator into the rotor, where they can be built onto the rotating magnetic feedback directly.

 

For the higher power range (DSM 117 – 190 series), the stator winding is inserted into the slotted armature with skewed stacks. The power output can be considerably increased thanks to the smaller magnetic air gap used in this method.
