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.
Our technology is extremely scalable, 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
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 weight and space
Increased lifetime of drive
Increased redundancy in 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.
