QD AIR-COOLED ASYNCHRONOUS MOTORS

Product catalog summary

Technical Specifications
The FQD series of water-cooled, speed-controlled AC motors and generators are designed for high-performance applications, offering power ratings from 1kW to 700kW. They are characterized by high power density and compact design, suitable for a wide speed range and high dynamic operation, ideal for industrial applications like injection molding machines, machine tools, and vehicle drives.

Design and Construction
The motors are fully enclosed with an integrated cooling jacket using water or oil, featuring prelubricated bearings and stable housing for high reliability and low maintenance. They comply with standards such as DIN EN 60034/VDE 0530-1, with mechanical mountings in B5, V1, B3, and B35 configurations.

Performance and Operation
The motors operate at constant torque up to a nominal speed and at constant power up to a higher speed, with power reduction beyond this speed. They are suitable for controlled drives with frequency inverters, and an encoder allows for field-oriented speed control.

Cooling System
The cooling system can handle aggressive mediums without corrosion prevention, using stainless steel or copper. The cooling water inlet temperature is set at 25°C, with higher temperatures requiring power reduction. Proper filtration is necessary to prevent pollution and silting.

Standards and Regulations
The motors comply with DIN EN 60034/VDE 0530 standards, available in insulation class F, offering protection levels from IP54 to IP65, with variable terminal box positions and cable configurations.

Additional Features
FQD motors offer low-noise operation and can be customized with various attachments, encoders, and brakes. They are balanced with a half fitting key and can be supplied with reduced vibration levels upon request.

General description Liquid-cooled OSWALD asynchronous motors and generators series FQD are particularly suitable when heavy demands are placed on a drive system. The motors are designed for wide speed range and high dynamic operation. OSWALD 4-pole FQD motors in power ranges from 1kW to 700kW are characterized by a high power density with small space requirements. The totally enclosed FQD motors are cooled over the integrated cooling jacket by water or oil. A high degree of reliability and low maintainance requirements result from use of prelubricated bearings as well as stable housing and bearing...
