WebDuring motor acceleration to synchronous speed (synchronous motors) or close to synchronous speed (induction motors), the current would initially rise to multiple times the rated current and cause voltage drop. Lower voltage while supply frequency is constant means lower V /Hz ratio and lower flux which affects the torque. WebSep 29, 2024 · PF R = cos (tan -1 (sX RO /R R) ) A graph of rotor P.F vs speed is drawn in the figure. As the torque induced (T ind) is proportionate to the product of the rotor field, net field, and power factor. The torque …
WebJun 5, 2016 · The accelerating curve represents the starting and running ampere characteristic curve of a motor for a given load inertia (Wk2), load torque-speed curve, and starting voltage. Typically, accelerating curves are provided at the motor rated voltage (100%) and the NEMA standard minimum rated locked rotor voltage (90%). WebApr 12, 2010 · In the last 15 years, the use of doubly fed induction machines in modern variable-speed wind turbines has increased rapidly. This development has been driven by the cost reduction as well as the low-loss generation of Insulated Gate Bipolar Transistors (IGBT). According to new grid code requirements, wind turbines must remain connected …
