🌊 ELECTRIC INBOARD ENGINE
The E1 Performance electric motor from EVOA represents a significant advancement in electric marine propulsion technology. Designed with an 800V advanced architecture, it delivers high efficiency, reduced emissions, and increased performance. The motor uses patented "Ecoflux Technology," maximizing energy utilization and achieving a best-in-class power-to-weight ratio. Its energy density of 200 W/kg ensures prolonged operation while minimizing system weight.
The motor comes in single and dual configurations. The single configuration produces 270 lb-ft of torque and 225 horsepower, suitable for standard marine applications. The dual configuration generates 540 lb-ft of torque and 450 horsepower, catering to high-performance requirements. This versatility allows the motor to power a variety of vessels.
The 800V system offers superior torque across its operating range, as shown in comparisons with traditional internal combustion engines. The motor maintains consistent torque delivery, peaking at 546 lb-ft, while ICE systems experience declines at higher RPMs. This consistent power delivery improves acceleration and vessel responsiveness.
