Properties of the three-phase AC motors
The long, slim three-phase AC motors made of extruded aluminium profile are optimally attuned to the CDA3000 inverter and the CDD3000 servocontroller. They usually construct a size smaller than standard IEC motors (with the same output in mode S1) and are dynamic as asynchronous servomotors.
What customizations are possible for three-phase AC motors?
* Protection up to IP66
* Special voltage and special rotation speed
* Specific connection technique
* Different design
* Cast motors
* Special shafts
* Flange adaption

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.

AC induction hoist and traction motors offer higher efficiency and smaller size than DC sepex or series wound motors with the same output and thermal performance.
They are without commutator and brushes and require no maintenance. With this type of motor, acceleration and braking torque at higher speeds are not limited by the commutator, which results in shorter stopping distances without the use of a mechanical brake. They also offer longer battery life and more precise control.
F e a t u r e s
• High specific power
• Low performance sensivity to motor temperature (no permanent magnets)
• Small size
• Low noise operation
• Long life maintenance free operation
• Excellent dynamic behavior
• Precise control
• EMC compatible

Product Overview
Our Weather Protected Type I (WPI)
Holloshaftâ motors are constructed to minimize the entrance of rain, snow and airborne particles. Our enclosures exceed NEMA requirements because U.S. Motors has built in the extra protection needed for rugged outdoor applications. The ventilation system is designed to provide optimum cooling to the thrust bearing and electrical components and is available in all motor sizes.
These motors allow for easy pump impeller adjustment and maintain alignment of pump base to motor drive clutches. Steady bushings are available to give the mechanical characteristics of a solid shaft motor.
In our design concept, the high thrust vertical motor is arranged into four functional zones - the top zone is small and light to assure simplified access to the coupling area and inspection of the thrust bearing. Below this is the coupling area and the essential elements of thrust bearings with a large weather protected air intake to cool the motor and thrust bearing.
Next, the center, or winding section, develops the driving torque and includes the latest Insulife insulation systems. And below, the mounting base is compact and designed for momentary upthrust of the pump.
The benefit of the four zone design is a motor which is more easily installed and serviced and which allow operator protection and convenience.
