Key advantages of permanent magnet (PM) motors

Permanent magnet motors (PM motors) represent an innovative approach to electric drives, offering a number of significant advantages over 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 to generate a magnetic field, as this is generated by the permanent magnets themselves. This eliminates energy losses in the rotor (reactive power losses and Joule losses), resulting in significantly higher efficiency, often exceeding the requirements of the IE4 Super Premium class. Efficiency is also maintained at a high level across a wide range of loads and speeds, particularly at lower speeds.
• Higher power factor: PM motors are characterised by a higher power factor, which means they draw less current from the mains for the same useful power. This benefits the entire electrical installation by reducing the load on the mains supply and lowering costs associated with reactive power.
• Compact design and higher power output: Thanks to the strong, 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 power, which is crucial in applications where space and weight are critical (e.g. electric vehicles, robotics).
• Constant torque and high dynamics: PM motors can generate constant torque, even at low speeds, and are characterised by rapid dynamic response. The low rotor inertia allows for rapid speed changes and precise control, which is ideal for applications requiring accurate positioning, such as CNC machine tools or industrial robots.
• Wide speed control range: Thanks to the ability to use field-weakening strategies, these motors can operate over a very wide speed range whilst maintaining high efficiency.
• Enhanced reliability and durability: Reduced heat build-up, a simpler rotor design (no windings) and lower mechanical loads result in longer and more reliable operation.

Inverter – the key to optimising compressor operation

An inverter (also known as a frequency converter) is an advanced electronic device that is revolutionising the way screw compressors operate. Its use allows for smooth regulation of the compressor motor’s rotational speed depending on the current demand for compressed air.

Key advantages of compressors fitted with an inverter:

• Significant electricity savings: This is the greatest advantage of the inverter. Traditional compressors either run at full capacity or are switched off, and excess air is often released. The inverter allows air production to be perfectly matched to consumption. The compressor operates only at the power level currently required, eliminating idling and losses resulting from start/stop cycles. This can lead to energy savings of between 20 and 50 per cent, depending on the air consumption profile.
• Stable pressure in the system: Thanks to the smooth regulation of the motor speed, the inverter compressor maintains an almost perfectly constant pressure in the compressed air network, regardless of fluctuations in demand. This is crucial for the proper functioning of pneumatic tools and machinery, prevents pressure surges and enhances the precision of manufacturing processes.
• Reduction of inrush currents and mains loads: The inverter ensures a smooth motor start-up, eliminating the high inrush currents that occur with a conventional star-delta start. This protects the electrical network from overloads and extends the service life of the motor and other components.
• Extended service life of components: Fewer abrupt starts and stops, as well as operation under optimal load conditions, significantly reduce mechanical wear on the screw block, bearings and motor. This translates into a longer service life for the entire compressor and lower maintenance costs.
• Quieter operation: When air demand is lower, the inverter reduces the motor speed, which directly lowers the noise level emitted by the compressor. This improves working comfort in the production hall or workshop.
• Greater flexibility and adaptability to requirements: An inverter compressor is ideal for applications with fluctuating compressed air demand, which is typical of most production facilities. It can operate efficiently under both light and heavy loads.
• Advanced control and diagnostics: Modern inverters are integrated with control panels, offering extensive functions for monitoring operating parameters, fault diagnostics, remote control and maintenance planning, giving you full control over the compressed air system.

Investing in an inverter-driven compressor pays for itself quickly thanks to significant energy savings and greater operational reliability. This solution is ideal for businesses that value efficiency, durability and optimised running costs.
