Three-phase asynchronous electric motor Oswald Elektromotoren

OSWALD asynchronous servomotors series QD are particularly suitable when heavy demands are required with respect to high speed range, dynamics, running smoothness and operational reliability.
OSWALD 4-pole QD motors in the power range from 1 kW to 150 kW have quadratic frames and are characterized by a high power density with a small space requirement. They are supplied in IP 54 to IP 65 enclosures
as well as in all relevant mountings (B3, B5, V1, etc.).
The standard version of the totally enclosed motor is cooled by an external axial blower. A high degree of reliability and low maintenance requirements result from the use of prelubricated bearings as well as stable housing and bearing plates.
The attachment of an incremental encoder or a resolver is designed, allowing field oriented speed control with a frequency converter. Motors without encoders can also be operated excellently through the use of a
frequency converter control.
The QD series is the result of many years of experience
with frequency controlled 3-phase squirrel cage
motors.
