EC external rotor

Our EC external rotor motors are available in a wide range. Small, high-speed drives differ fundamentally in their properties and design from low-speed, multi-pole power packs.

External rotor means that the rotor sits on the stator and the “outside” of the motor rotates. Our EC internal rotor motors and all brushed DC motors, as well as all bell-type armature motors, are the opposite. Here the rotor is on the inside, the “inside” of the motor rotates.

Similar to the other motor types (brushed DC motors and bell-type armature motors), we also have a wide range of customization and combination options for BLDC motors:

Customer-specific customization options

  • Customized motor flanges with almost freely selectable connection dimensions allow easy adaptation to our customer’s application
  • We determine the motor shaft length on the front of the motor individually in consultation with our customers
  • Within the scope of technical possibilities, the shafts can be provided with a (single or double) flattening (D-cut), a hexagon or other geometries
  • Cost-neutral adjustments to the motor winding allow us to achieve your operating points even under demanding conditions.
  • Many EC motors are available both sensorless and with Hall sensors
  • We can also supply a suitable controller for testing on request
  • Cable type, length and connector are freely selectable
