OSWALD asynchronous servomotors of the QD series are designed for high-performance applications with a wide speed range and dynamic response. These 4-pole motors, ranging from 1 kW to 150 kW, feature a compact design and are available in protection classes IP 54 to IP 65. They are cooled by an external axial blower and equipped with prelubricated bearings for reliability and low maintenance. Incremental encoders or resolvers can be fitted for field-oriented speed control using a frequency converter.
The QD series motors are suitable for machine tools, vehicle drives, theater drives, packaging machines, extruders, textile machines, wire drawing machines, and printing machines.
The motors comply with DIN EN 60034/VDE 0530 Part 1 and EN 60034-1. They adhere to DIN standards for attachment dimensions, with some exceptions. Shaft and flange tolerances are within class N according to DIN 42955, with reduced tolerances available upon request.
Motors are available with IP 54 to IP 65 enclosures. Power ratings are specified for nominal speeds of 1500 rpm and 2100 rpm, with continuous and intermittent operation ratings provided. Custom speed ranges and voltages are available.
External ventilation ensures effective cooling, with a maximum cooling air temperature of 40°C and a setup altitude limit of 1000 m. The motors operate below the noise levels specified by EN 60034-9.
The motors have insulation class F, with high-quality winding insulation to withstand voltage spikes. Vibration levels are classified into three severity levels, with QD motors supplied in the reduced severity class R.
Balancing is performed with a half featherkey according to DIN ISO 8821. The motors typically use deep groove ball bearings designed for a minimum of 20,000 hours of operation. Cylindrical roller bearings or precision spindle bearings can be used for higher loads or extended speed ranges.
Various attachments, such as encoders and brakes, can be customized. The terminal box and cable outlets can also be adapted as needed.
OSWALD maintains a quality control system certified to DIN EN ISO 9001 standards. Qualified personnel are available for installation, commissioning, and maintenance services, with spare parts typically shipped on the same day.
The document outlines customization options for motor components such as encoders and brakes. Standard encoders can be specified, and motor brakes can be adapted to customer preferences, with options for single disc or flap brakes.
The terminal box position and cabling can be customized. The standard position is on top with PG bolts to the right, but variants include right or left positioning. The terminal box can be rotated, and alternatives like simple cabling or plug connectors are available.
The document provides detailed technical specifications for the QD motor series, including nominal ratings at 50 Hz and 70 Hz, with various power outputs, efficiencies, and dimensions.
Besides the QD series, the company offers the FQD series with water-cooled motors, the QDI series with external ventilation, and a range of DC motors with various protection levels.
The document provides contact details for Elektromotoren GmbH, including phone, fax, email, and website information.

Normalerweise sind die Motoren der QD-Reihe mit Rillenkugellagern ausgerstet. Die Lager sind fr eine Lebensdauer von mindestens 20.000 h dimensioniert, zul켤ssige Belastungswerte knnen auf Anfrage ange- geben werden. Bei hoher Radialbelastung sind Zylin- derrollenlager oder Doppellager einzubauen. Um hhe- re Schwingg涼ten oder einen erweiterten Drehzahlbe- reich zu erhalten, knnen Genauigkeits-Spindellager eingesetzt werden. The motors of the QD series are usually equipped with deep groove ball bearings. The bearings are designed for a lifetime of at least 20,000 hours. Admissible load values can...
