Main advantages of PM (Permanent Magnet) motors

Permanent Magnet Motors (PM Motors) represent an innovative approach in electric drives, offering a number of significant advantages compared to traditional induction motors.

• Higher energy efficiency: One of the main benefits. PM motors do not require current to be supplied to the rotor to generate a magnetic field, as this is produced by permanent magnets. This eliminates rotor energy losses (reactive and Joule losses), resulting in significantly higher efficiency, often exceeding IE4 Super Premium class requirements. Efficiency remains high across a wide range of loads and speeds, especially at low RPMs.
• Higher power factor: PM motors have a higher power factor, meaning they draw less current from the mains for the same useful power. This benefits the entire electrical installation by reducing grid load and lowering reactive energy costs.
• Compact design and higher power: Thanks to the strong, constant magnetic field generated by the magnets, these motors can deliver more power in a smaller housing. They are lighter and more compact than induction motors of comparable power, which is crucial in applications where space and weight matter (e.g. electric vehicles, robotics).
• Constant torque and high dynamics: PM motors can generate constant torque even at low speeds and feature a rapid dynamic response. Low rotor inertia allows for quick speed changes and precise control, ideal for applications requiring high positioning accuracy such as CNC machines or industrial robots.
• Wide speed control range: By applying field-weakening strategies, these motors can operate efficiently over a wide speed range.
• Increased reliability and durability: Reduced heating, simpler rotor design (no windings), and lower mechanical stress result in longer and more reliable operation.

Inverter / VSD – the key to compressor optimisation

The inverter (also called a variable speed drive) is an advanced electronic device that revolutionises the operation of screw compressors. It allows smooth control of the compressor motor speed depending on the current demand for compressed air.

Key advantages of inverter-equipped compressors:

• Significant energy savings: This is the inverter’s greatest advantage. Traditional compressors work at full output or are switched off, often releasing excess air. The inverter perfectly matches air production to consumption. The compressor runs only with the required power, eliminating idle running and start/stop losses. This can reduce energy consumption by 20–50%, depending on air demand profiles.
• Stable system pressure: With smooth motor speed control, the inverter maintains nearly constant pressure in the compressed air network, regardless of demand fluctuations. This ensures proper operation of pneumatic machines and prevents pressure surges, increasing process precision.
• Reduced inrush current and grid load: The inverter enables smooth motor start-up, eliminating high current peaks typical of star-delta starts. It protects the electrical system from overloads and extends motor and component life.
• Extended component life: Fewer abrupt starts and stops and operation under optimal load conditions reduce mechanical wear of the screw block, bearings and motor. This extends compressor life and lowers maintenance costs.
• Quieter operation: When air demand is low, the inverter reduces motor speed, directly decreasing noise levels. This improves comfort in workshops and production halls.
• Flexibility and adaptability: Inverter compressors are ideal for applications with variable air consumption typical of most manufacturing plants. They can efficiently operate under both low and high loads.
• Advanced monitoring and diagnostics: Modern inverters are integrated with control panels offering advanced monitoring, fault diagnostics, remote control and maintenance scheduling functions, providing full system control.

Investing in an inverter-equipped compressor quickly pays off through substantial energy savings and increased reliability. It is an ideal solution for companies valuing efficiency, durability and cost optimisation.
