Since decades electric driven venetian blinds for the outside became established and meanwhile one cannot imagine big buildings without them because of comfort and efficiency. Dunkermotoren as a supplier of venetian blind motors was decisively involved in this development.

Today's venetian blind motors are the result of decades of experience and co-operation with manufacturers of blind systems. The constant development process, which results out of this co-operation, led to products of a high level in technique and quality.

During the development different requirements had to be considered. For example

• possibility for mounting in different head-rails
• end-limit-switches for the upper an lower end position
• keeping the blind in every position when the motor doesn't run
• minimum of running noise
• free of maintenance during a lifetime of at minimum ten years
• correct function in different environment conditions

The venetian blind motors are AC-induction motors for short-time-operation with mounted gear boxes. The motors are robustly constructed and maintenance-free during their life-time. The winding has a built-in temperature-switch, which protects the motor against damaging because of excessive stress. The rotor is a squirrel-cage rotor. The built-in electro-mechanical brake ensures a safe keeping of the load.

Standard equipment of the motors

• built-in capacitor
• connector cable, length: 0,5 m
• connector

For different applications single- and double-shaft motors are available in different versions.

• D240:
  lower end positions fixed, external limit switch for the upper end positions
• D249, D349, D339, D739, D839:
  adjustable lower and upper end limits, additional external limit switch for the upper end positions
• D248, D348, D838:
  two lower end postions, external limit switch for the upper end position
