S3000 - On-Road "Helper" Motor/Generator System

Retrofit/conversion packages for GVWR Class 3-6 trucks -- shuttle buses, school buses, delivery trucks, dump trucks. The S3000 motor mounts on the vehicle driveshaft.  During acceleration electric motor assists internal-combustion engine.  During braking, motor becomes generator and recharges supercapacitors.  In intensive start/stop applications, this retrofit system increases mpg 25-40%.

S2000 - Electric Vehicle Traction Motors

Designed for 100% electric and converting GVWR Class 1-2 trucks to hybrid-electric.  Like the S3000, these brushless DC motors feature the patented Vari-Torque™ shift for continuously extended speed ratios, replacing conventional transmissions. Single brushless motors up to 60HP.
