Nfo Drives Ab — Investor Presentation (November 2023)
20 slides from Nfo Drives Ab's investor presentation, November 2023
Slide 1: Interference free future
Interference free future NFO Drives unique frequency inverter SIMPLE SILENT SAFE
Slide 2: Energy saving
Energy saving By controlling motors with frequency inverters, you can save up to 70% energy - sometimes more. NFO Drives AB – Sweden – www-nfodrives.se
Slide 3: Electrical motors
Electrical motors Motors have always been fed with sinusoidal voltages until variable frequency drives started to be used Variable frequency drives are used to control the speed of the motor. The benefits are: ▪ Energy savings ▪ Control performance NFO Drives AB – Sweden – www-nfodrives.se
Slide 4: Hear the difference between NFO Sinus and PWM
Hear the difference between NFO Sinus and PWM (video in Swedish)
Slide 5: Pure sinus: cost effective and simple installation
Pure sinus: • Cost effective and simple electrical installation ▪ Installed with unshielded cables ▪ No special requirements for an electrical installer ▪ Easy to install ▪ Plug and play • Possibility of free position NFO Sinus can be placed at an unlimited distance from the electric motor. It can b
Slide 6: Pure sinus: healthy motor, interference-free
Pure sinus: • Healthy motor No bearing currents – no bearing damage. • Interference-free NFO's frequency inverter is interference-free, which means major benefits primarily for the end customer. • Residual-current device (RCD) can be used NFO Sinus does not generate ground currents (max. 2 mA). NFO
Slide 7: Consequences of PWM technology
Consequences of PWM technology: Electrical installation ▪ Requires expensive EMC rated shielded cable ▪ Requires filter ▪ Installer with EMC competence required ▪ Complicated rules make installation difficult • Fixed positions Requirements for short motor cables mean that the inverter must be placed
Slide 8: PWM-technique vs Sinus-technique
PWM-technique: Expensive and Fixed position Bearing failure Interferences Impaired personal complicated electrical and fire safety installation Sinus-technique: Cost effective and Free position Healthy motor Interference-free RCD, ground-fault simple electrical circuit breaker, can installation be u
Slide 9: Our customers
Our customers: Food industry Healthcare Pump & Water systems Defence industry NFO Drives AB – Sweden – www-nfodrives.se
Slide 10: SAAB Kockums
SAAB Kockums ▪ NFO Sinus is the first inverter approved for naval vessels. ▪ The use of frequency inverters has not previously been allowed at all. Inverters interfered with the sensitive equipment on board and were therefore banned within the Navy. ”We tested NFO Sinus frequency inverter in our own
Slide 11: Oslo Rikshospital
Oslo Rikshospital Ventilation and pump control. ▪ Oslo University Hospital HF, the National Hospital, have replaced more than 600 conventional PWM-type inverters with interference-free NFO Sinus inverters. “Since we switched over, we have had none of the problems involved with PWM inverters. The mot
Slide 12: Waterworks
Waterworks ▪ Two water pumps are controlled by NFO Sinus frequency inverters. ▪ The frequency inverters have been placed at the waterworks. ▪ Distance between water works and the wells = 460 m. ▪ Existing unshielded 3-phase cable has been used. NFO Drives AB – Sweden – www-nfodrives.se
Slide 13: Melotte – Pump technology
Melotte – Pump technology Melotte produces an extensive range of submersible pump units and submersible motors. Why NFO Sinus was chosen: ▪ Possibility to use long cables. ▪ Safety aspect - as pumps/motors are under water. ▪ Healthy motors. NFO Drives AB – Sweden – www-nfodrives.se
Slide 14: Kährs Nybro
Kährs Nybro ▪ Kährs in Nybro manufactures 6 million m2 of flooring per year. ▪ Brush machines for surface treatment of various floors are controlled by NFO Sinus frequency inverters. ▪ The motors can be run with full torque even at low rpm (15-18 Hz). ▪ The motors do not overheat. ▪ Low heat losses.
Slide 15: Guldfågeln- Mörbylånga
Guldfågeln- Mörbylånga Changes in production required the speed of the conveyor belt to be regulated by frequency inverters. Conventional inverters had required extensive remodelling and rebuilding of the production line. One NFO Sinus inverter could control all 8 motors and: ▪ 360 m unshielded cabl
Slide 16: Guldfågeln- Mörbylånga
Guldfågeln- Mörbylånga Guldfågeln chose Plug & Play-solution from NFO Drives NFO Drives AB – Sweden – www-nfodrives.se
Slide 17: DeLaval - a part of Tetra Laval Group
DeLaval - a part of Tetra Laval Group Why NFO Sinus was chosen: ▪ No interference on all other farm equipment ▪ Reliable automatic identification of the animals ▪ No earth leakage currents which affect the animals ▪ No ball-bearing damages Result: ▪ High operating reliability ▪ High product quality
Slide 18: Dancing Water system
