Description
A synchronous reluctance motor (SynRM) creates torque due to the magnetic anisotropy of the rotor, that is, the rotor aligns with the stator field and rotates synchronously with it. It has no magnets, so the cost is lower and there is no dependence on rare-earth materials. Unlike an induction motor, there are almost no losses in the rotor. The geometry of the rotor lamination was developed jointly with the Technical University of Darmstadt and a plastics machinery manufacturer, and the width of the bridges and air gaps was optimized for maximum efficiency while keeping mechanical strength. The motor is powered from a matched frequency converter, which gives synchronization, precise control of torque and speed, and simpler setup. The water jacket removes heat, reduces thermal load and increases power density. The manufacturer considers this efficiency level practically unattainable for induction technology. The motors are made in Austria. Frame size tables are absent in the source, and only an information sheet is available.
How to choose
The motor is chosen if the drive is variable-speed and maximum energy efficiency is needed. It replaces induction motors of class IE2 or IE3 in drives with a frequency converter and reduces energy consumption. The power up to 500 kW covers extruders, injection moulding machines and plastics processing lines, as well as the chemical, pharmaceutical, food and textile industries. For higher powers look at MKH water-jacketed induction motors up to 2500 kW of class IE4.

FAQ
What energy efficiency class does this motor have?
IE5, that is, ultra-premium, for powers up to 500 kW.
Does a synchronous reluctance motor contain magnets?
Not necessarily, so its cost is lower and there is no dependence on rare-earth materials.
Can the motor be powered directly from the mains?
No, it is powered from a matched frequency converter, which gives synchronization and torque control.
How is the motor cooled?
By a water jacket, which removes heat and reduces thermal load.
Can it replace an induction motor?
Yes, in variable-speed drives it replaces IE2 or IE3 motors to reduce energy consumption.
