Specification: Ziehl-Abegg external rotor motors combine the advantages of compact and space saving construction with the proven drive concept of a wear-free squirrel cage motor. 9 frame sizes are available in an output range of 0.1 to 7 kW and 2 constructional designs for flange or axis fastening. These external rotor motors are 100% speed controllable. Electronically commutated direct-current motors including the necessary EC controllers are also available. They are effective in many applications through their constant torque and high efficiency.
Specification: For simple manual speed regulation 5-step transformer-based controllers for single-phase and three-phase fans are available. We supply the corresponding switchgear for multi-speed motors. Motor protection devices are available for thermal monitoring based on thermostats or thermistors (PTC).
Attributes and special features: Rugged design technology, well priced.
Applications: Air conditioning, refrigeration, heating technology, agriculture
