Product catalog summary
Synchronous Reluctance Motors Overview
Synchronous reluctance motors (SynRM) are designed for high efficiency and reliability, reducing the cost of ownership. They utilize a conventional stator with an innovative rotor design that eliminates magnets and windings, minimizing power losses and simplifying maintenance.
Key Features
  • Efficiency: Achieves IE5 efficiency class per IEC TS 60034-30-2, with reduced energy consumption and environmental impact due to the absence of rare earth metals.
  • Reliability: Low winding and bearing temperatures extend motor life and service intervals.
  • Control: Offers precise speed and torque control, suitable for applications like pumps, fans, extruders, and conveyors.
  • Retrofit Compatibility: Matches the size of IE2 induction motors, allowing easy retrofits without mechanical changes.
Technical Specifications
  • Efficiency Standards: International MEPS for VSD-only motors are in development, with no local requirements as of September 2022.
  • Serviceability: Similar to induction motors, with easy disassembly and servicing.
  • Insulation and Bearing Protection: Standard insulation for 500 V VSD supply, with additional measures for higher voltages. Motors above 100 kW have insulated bearings to prevent bearing currents.
  • Cabling and EMC: Requires shielded cables and EMC glands for proper grounding and electromagnetic compatibility.
Design and Technology
  • Rotor Design: Features a magnetically anisotropic rotor structure with high and low permeance axes, enhancing torque production.
  • Functional Principle: Operates by aligning the rotor's d-axis with the magnetic field, controlled by a frequency converter for precise performance.
  • Construction: Rotor made of stacked electric steel plates with flux barriers, resulting in cooler operation and increased efficiency.
Applications and Benefits

Typical standard low voltage induction motor efficiency is determined according to IEC 60034-30-1 in sinusoidal (DOL) supply. The IE class limit values in new IEC TS 6003430-2 are reduced by adding the additional harmonic losses caused by the drive: – 15% additional losses for motors up to 90kW 25% additional losses for motors above 90kW Limit values available also for IE5 level...

Technology Introduction The synchronous reluctance motor is a threephase electric motor with a magnetically anisotropic rotor structure. In the four-pole version, the rotor has four high- and four low-permeance axes. High permeance means high magnetic conductivity and higher inductance, while low permeance means lower inductance. Reluctance is the inverse of permeance and is, in practical terms, magnetic resistance; high reluctance results in low inductance. The axes with high permeance can be referred to as the direct or d-axis, while the axes with high reluctance can be referred to as the quadrature...
