Main Advantages of Permanent Magnet Motors (PM Motors)

Permanent magnet motors represent an innovative approach to electric drives, offering significant advantages over traditional induction motors.

• Higher energy efficiency: PM motors do not require current to be supplied to the rotor to generate a magnetic field, as it is produced by permanent magnets. This eliminates rotor losses, resulting in much higher efficiency, often exceeding IE4 Super Premium class requirements. Efficiency is maintained across a wide load and speed range, particularly at lower speeds.
• 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 system by reducing load and reactive power costs.
• Compact design and higher power density: Thanks to the strong magnetic field generated by the magnets, these motors deliver more power in a smaller housing. They are lighter and more compact than induction motors of equivalent power, which is vital in applications where space and weight matter (e.g. electric vehicles, robotics).
• Constant torque and high dynamics: PM motors deliver constant torque even at low speeds and exhibit rapid dynamic response. The rotor’s low inertia allows fast speed changes and precise control—ideal for CNC machines or industrial robots.
• Wide speed control range: With magnetic field weakening strategies, these motors can operate across a broad speed range while maintaining high efficiency.
• Increased reliability and durability: Less heat generation, simpler rotor construction (no windings) and reduced mechanical stress ensure longer, more reliable service life.

Inverter / VSD – The Key to Optimising Compressor Operation

The inverter (also called frequency converter) is an advanced electronic device that revolutionises how screw compressors operate. It allows smooth adjustment of motor speed according to current air demand.

Key benefits of compressors equipped with inverters:

• Significant electricity savings: This is the biggest advantage. Traditional compressors operate at full capacity or are switched off, often wasting excess air. The inverter precisely matches air production to consumption, eliminating idle running and start/stop losses. Energy savings of 20–50% are possible depending on air usage profile.
• Stable pressure: Smooth motor speed control maintains almost perfectly constant air pressure, regardless of demand fluctuations. This ensures tool reliability and process precision.
• Reduced start-up currents: The inverter ensures smooth motor starts, avoiding high inrush currents typical in star-delta starting systems. This protects the electrical network and extends the life of the motor and components.
• Extended component life: Fewer start-stop cycles and optimal load operation reduce mechanical wear on the screw block, bearings and motor, lowering service costs.
• Quieter operation: When air demand is lower, the inverter reduces motor speed, which directly decreases noise levels — ideal for workshops and production halls.
• Greater flexibility: Perfect for applications with variable air demand, typical in most production facilities. It operates efficiently at both low and high loads.
• Advanced control and diagnostics: Modern inverters integrate with control panels, offering advanced monitoring, fault diagnostics, remote control and maintenance scheduling — providing full control of your compressed air system.

Investing in an inverter-driven compressor quickly pays off thanks to energy savings and increased reliability. It is the ideal choice for companies that value efficiency, durability and operational optimisation.
