LEAN DRIVE

STADT LEAN Drive is a patented solution for start and control of big electrical motor loads. Especially developed for marine propulsion systems where it can be used on any propeller with controllable pitch.

STADT LEAN Drive is extremely reliable and offers a long lifespan of 30 years or more. This durability is achieved by using fewer components in the drive system, as well as different parallel power technologies that are redundant to each other.

 

 

RANGE

The STADT LEAN Drive is a scalable technology. Available in any voltage, configuration and for all vessel types without the use of transformers. 
    220 V - 15 kV
    100 kW - 30 MW per motor
    Stealth execution for naval
 

 

 

FEATURES

The STADT LEAN Drive has many unique features compared to traditional electric propulsion systems.

 

 

    No LOSS when in bypass
    No THD when in bypass
    No EMI when in bypass
    No PWM when in bypass
    Sinus voltage and current
    Less complexity
    Less weight and space
    Increased lifetime of drive
    Increased redundancy in drive
    Air cooled drive
    Scalable in power
    Scalable in voltage

 

These unique features are achieved by using a combination of a multi-speed motor, transistors (VFD), thyristors (RVS) and circuit breakers (BP) together with a controllable pitch propeller (CPP), where we use the different technologies in sequence and where they are best. With the STADT LEAN Drive we achieve a robust and reliable drive system where the dependence of critical components is reduced to a minimum, while the redundancy is increased.
