Motor speed curve
Nettet11. apr. 2024 · Vertical curve is the transition curve at the change of longitudinal slope. The choice of radius and length of vertical curve not only affects driving safety and driver’s comfort [ 23 ], but also causes the driver to reduce the gear to change driving speed, which in turn affects the fuel consumption and carbon emission of the car [ 24 ]. NettetAn SPMSM has equal d -axis and q -axis inductances. An IPMSM has a higher q -axis inductance than its d -axis inductance. This helps the IPMSM to utilize the reluctance …
