Design requirements: extra traction, increased torque Developed specifically for traction and higher low-speed torque loads, and applications for which starting torque requirements are greater than continuous torque requirements, the electric-drive system uses multi-phase motors in which the windings connect several inverter terminals to each other, and are not grounded in the conventional way. The different connectors act like different gear rates, and the motor can electronically change “gears” by operating the inverter at the harmonics of the drive frequency. The system therefore uses harmonic drive to essentially fool the drive electronics into thinking they are operating at a higher speed. The net benefit is that the motor drive is capable of achieving five times the torque speed of a similarly sized unit and is therefore much smaller and lighter. |

大俠,我查了兩天,,也沒找到您說的很輕的大功率發(fā)動機,,尤其是摩托車發(fā)動機,,能否給個型號或者網址,?謝謝

先搞清楚最低重量需求再考慮是否該減肥和如何減肥,。POWERPUSH只有55.1kw的功率。一輛思域就有103kw,,但是你 ...
