Main advantages of PM permanent magnet motors

Permanent Magnet Motors (PM motors) represent an innovative approach to electric drive systems, offering a number of significant advantages over traditional induction motors.

• Higher energy efficiency: One of the key benefits of PM motors. They do not require electrical current to be supplied to the rotor to generate a magnetic field, as it is created by the permanent magnets themselves. This eliminates rotor losses (reactive power loss and Joule losses), resulting in significantly higher efficiency, often exceeding IE4 Super Premium efficiency class requirements. High efficiency is maintained across a wide range of loads and speeds, especially at lower rotational speeds.
• Higher power factor: PM motors feature a higher power factor, meaning they draw less current from the electrical network for the same usable output power. This benefits the entire electrical installation by reducing network load and lowering costs associated with reactive power.
• Compact design and higher power density: Thanks to the strong, constant magnetic field generated by the magnets, these motors deliver higher power in a smaller housing. They are lighter and more compact than induction motors of comparable output, which is crucial in applications where space and weight matter.
• Constant torque and high dynamics: PM motors can generate constant torque even at low speeds and offer fast dynamic response. Low rotor inertia allows rapid speed changes and precise control, making them ideal for applications requiring accurate positioning, such as CNC machines and industrial robotics.
• Wide speed control range: Through the use of magnetic field weakening strategies, these motors can operate over a very wide speed range while maintaining high efficiency.
• Increased reliability and durability: Lower operating temperatures, simpler rotor construction (no windings), and reduced mechanical stress result in longer service life and higher reliability.

Inverter / Variable Frequency Drive – the key to compressor optimisation

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

Key advantages of inverter-driven compressors:

• Significant energy savings: This is the greatest advantage of inverter technology. Traditional compressors operate at full capacity or shut down, often venting excess air. The inverter precisely matches air production to consumption, eliminating idle running and losses caused by frequent start/stop cycles. This can result in energy savings of 20–50%, depending on the air demand profile.
• Stable system pressure: Thanks to smooth motor speed control, the inverter compressor maintains nearly constant pressure in the compressed air network, regardless of demand fluctuations. This is essential for the correct operation of pneumatic tools and machines, prevents pressure surges, and increases process precision.
• Reduced inrush currents and network load: The inverter provides soft motor start-up, eliminating high current peaks associated with traditional star-delta starting. This protects the electrical network and extends the service life of the motor and other components.
• Extended component lifespan: Fewer sudden starts and stops, combined with operation under optimal load conditions, significantly reduce mechanical wear of the screw block, bearings, and motor, resulting in longer compressor life and lower maintenance costs.
• Quieter operation: When air demand is lower, the inverter reduces motor speed, directly lowering noise emissions and improving workplace comfort.
• Greater flexibility and adaptability: Inverter compressors perform exceptionally well in applications with variable air demand, which is typical for most production facilities.
• Advanced control and diagnostics: Modern inverters are integrated with control panels, offering extensive monitoring, fault diagnostics, remote control, and maintenance planning functions.

Investing in an inverter-driven compressor pays back quickly through significant energy savings and increased operational reliability. It is an ideal solution for companies that value efficiency, durability, and optimised operating costs.
