Main advantages of PM motors (Permanent Magnet Motors)
Permanent Magnet Motors (PM Motors) represent an innovative approach in electric drives, offering a number of significant advantages compared with traditional induction motors.
- Higher energy efficiency: PM motors do not require current to the rotor to generate a magnetic field, as it is produced by permanent magnets. This eliminates rotor energy losses and provides efficiency often exceeding the IE4 Super Premium class, even at lower speeds.
- Higher power factor: PM motors draw less current for the same power output, reducing network load and reactive energy costs.
- Compact structure and higher power density: Thanks to their strong constant magnetic field, these motors can deliver higher power in a smaller housing, making them lighter and more compact – ideal where space and weight are critical (e.g. robotics, automation).
- Constant torque and high dynamics: PM motors deliver constant torque even at low speeds and provide quick dynamic response, perfect for CNC machines or industrial robots.
- Wide speed control range: Using field-weakening strategies, they maintain high efficiency across a wide range of speeds.
- Improved reliability and durability: Reduced heating, simplified rotor design (no windings) and lower mechanical loads ensure long and reliable operation.
Inverter – the key to compressor performance optimisation
An inverter (also known as a frequency converter) is an advanced electronic device that revolutionises screw compressor operation. Its use allows smooth adjustment of compressor motor speed depending on current compressed-air demand.
Key advantages of inverter-equipped compressors:
- Significant energy savings: The inverter allows precise adjustment of air production to demand, eliminating idle operation and losses from start/stop cycles. This can lead to energy savings of 20–50% depending on usage profile.
- Stable system pressure: Smooth motor speed control keeps air system pressure nearly constant, regardless of fluctuations in consumption. This is crucial for pneumatic tools and machines, preventing pressure surges and improving process accuracy.
- Reduced inrush current and electrical load: The inverter provides a soft start, protecting the electrical grid and extending motor and component life.
- Extended component lifetime: Fewer start/stop cycles and operation under optimal load reduce wear on the screw block, bearings and motor, resulting in longer compressor life and lower maintenance costs.
- Quieter operation: When air demand is low, the inverter reduces motor speed, lowering the noise level emitted by the compressor and improving working comfort.
- Greater flexibility and adaptability: Perfect for applications with variable air demand, efficiently operating at both low and high loads.
- Advanced control and diagnostics: Modern inverters integrate with control panels to provide monitoring, fault diagnostics, remote control and maintenance scheduling – giving you full control of the air system.
Investing in an inverter-equipped compressor pays off quickly thanks to substantial energy savings and enhanced reliability – ideal for companies seeking efficiency, durability and operating-cost optimisation.
