Main Advantages of Permanent Magnet (PM) 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: This is one of the key advantages. PM motors do not require current to be supplied to the rotor in order to generate a magnetic field, as it is created by the permanent magnets themselves. This eliminates rotor energy losses (reactive power loss and Joule losses), resulting in significantly higher efficiency, often exceeding IE4 Super Premium class requirements. Efficiency is also maintained at a high level across a wide range of loads and speeds, particularly at lower revolutions.
• Higher power factor: PM motors feature a higher power factor, meaning they draw less current from the electrical network for the same usable power. This benefits the entire electrical installation, reducing network load and lowering costs associated with reactive energy.
• Compact design and higher power density: Thanks to the strong and constant magnetic field generated by the magnets, these motors can deliver greater power within a smaller housing. They are lighter and more compact than induction motors of comparable output, which is crucial in applications where space and weight are important.
• Constant torque and high dynamics: PM motors can generate constant torque even at low speeds and offer rapid dynamic response. Low rotor inertia enables quick speed changes and precise control, making them ideal for applications requiring accurate positioning such as CNC machines or industrial robots.
• Wide speed control range: Thanks to the possibility of applying magnetic field weakening strategies, these motors can operate across a very wide speed range while maintaining high efficiency.
• Increased reliability and durability: Reduced heat generation, simpler rotor construction (no windings) and lower mechanical loads translate into longer and more reliable operation.

Inverter / Variable Speed Drive (VSD) – the key to optimising compressor performance

The inverter (also known as a frequency converter) is an advanced electronic device that revolutionises the operation of screw compressors. Its application allows smooth regulation of the compressor motor speed depending on current compressed air demand.

Key advantages of compressors equipped with an inverter:

• Significant electricity savings: This is the main advantage of the inverter. Traditional compressors operate at full capacity or are switched off, and excess air is often released. The inverter allows precise matching of air production to consumption. The compressor operates only at the power currently required, eliminating idle running and losses resulting from start/stop cycles. This can result in energy savings of 20–50% depending on the air consumption profile.
• Stable system pressure: Thanks to smooth motor speed control, the inverter compressor maintains almost perfectly constant pressure in the compressed air network, regardless of demand fluctuations. This is crucial for proper operation of pneumatic tools and machinery, preventing pressure surges and increasing process precision.
• Reduced starting currents and network load: The inverter ensures a soft motor start, eliminating high inrush currents typical of conventional star-delta starting. This protects the electrical network from overload and extends the lifespan of the motor and other components.
• Extended component lifespan: Fewer abrupt starts and stops and operation under optimal load conditions significantly reduce mechanical wear of the screw block, bearings and motor. This translates into longer compressor life and lower service costs.
• Quieter operation: When compressed air demand is lower, the inverter reduces motor speed, directly lowering the noise level emitted by the compressor. This increases comfort in workshops and production halls.
• Greater flexibility and adaptability: An inverter compressor performs perfectly in applications with variable compressed air demand, typical for most production facilities. It operates efficiently under both low and high load conditions.
• Advanced control and diagnostics: Modern inverters integrate with control panels, offering extensive monitoring of operating parameters, fault diagnostics, remote control and maintenance planning, providing full control over the compressed air system.

Investing in a compressor with an inverter quickly pays off thanks to significant energy savings and higher operational reliability. It is an ideal solution for companies that value efficiency, durability and operating cost optimisation.
