QWC/SEV-55kW peak-100Vdc-RF/M1616-SG4S6 - This system is quite similar to what Zero Motorcycle uses, the differences are: motor is this package has more flux in the rotor and more magnet material, for a higher power in the same size package.  Compare our rotor on left to Zero on right. Both have the same stator winding, however our motor is liquid-cooled for higher cont. power, where Zero’s is air-cooled - we also sell an air-cooled version with less cont. power capability.  

Kit contains: IP67 motor/controller (size 6 controller picture),, controller chill plate, contactor, low voltage wiring harness, 3 hours tech support.  Peak Power 73hp / 55kW for 10 secs, Peak Torque ~88ft-lbs/120nm, 67hp / 50kW for 120 secs, Continuous/Rated Power 27HP / 20kW, Cont. torque  32 ft-lbs./ 44nm, motor torque constant ~.2/nm and Max RPM 8,000*, Motor Weight ~48lbs, Controller Weight w/ chill plate ~11lbs. Motor and Controller Picture  *Field Weakening required
