Unlike traditional PWM (pulse width modulation) inverters that generate voltage through short pulses and cause electromagnetic interference, NFO Drives inverters deliver a pure sinusoidal voltage. This eliminates interference in both conducted and radiated signals, making them suitable for sensitive environments such as medical institutions or residential buildings.
NFO Drives converters do not require shielded cables between the inverter and the motor. This not only reduces installation costs but also simplifies the process by eliminating the need for expensive EMC-certified accessories.
With NFO Sinus frequency converters, the distance between the motor and inverter can reach several hundred meters. The only limiting factor is cable resistance, requiring an appropriate cable cross-section. This allows centralized placement of the inverter for easier maintenance, regardless of the motor’s location.
Thanks to the pure sinusoidal voltage, motors operate without the typical “whining” or irritating noise associated with conventional inverters. This improves the working environment and extends motor lifespan by preventing bearing damage caused by electrical discharges.
NFO frequency inverters do not produce ground currents, which prevents interference with technical equipment and enhances safety. This allows the use of automatic ground fault breakers for human and fire protection—traditionally problematic with other inverter types.
While NFO Drives technology may seem futuristic, it is already being used successfully across various industries. According to Affärsvärlden, the company’s clients include industry giants like SAAB Kockums (submarine manufacturing), Siemens, and DeLaval—all with high demands for motor control and electromagnetic compatibility.
These real-world applications serve as strong proof of the technology’s quality and reliability—especially in areas where interference or vibration can pose risks or disruptions. In such cases, the NFO sinusoidal voltage ensures safe and quiet motor operation.
Installing NFO Drives frequency converters is significantly simplified due to their technological advantages:
No shielded cables required: This reduces material costs and simplifies installation by eliminating the need for costly EMC-certified accessories.
Flexible inverter placement: The inverter can be installed far from the motor, allowing easy access for maintenance regardless of the motor’s location.
Simplified EMC compliance: The pure sinusoidal voltage eliminates electromagnetic interference, easing compliance with EMC directives and reducing the need for additional filters or protection measures.
NFO Drives frequency inverters offer an innovative approach to electric motor control, combining technological excellence with installation simplicity.
NFO Drives’ unique features—such as pure sinusoidal output voltage and the absence of ground currents—make them the ideal choice across industries where energy efficiency, reliability, and easy installation are crucial. At ZTF Lāsma, we are proud to offer these advanced solutions to help you reach higher efficiency and safety standards in your systems.
