Torque and Speed

WebWhether measured in kg-cm, lb-in, or Nm, torque is the amount of load the motor or gear motor output shaft can overcome. On a dc motor / gear motor performance curve, torque is usually represented by the X-axis. The intersection of the speed line ( N) and the X-axis is the stall torque (T) point. This is where the motor produces its maximum ... WebMay 28, 2024 · The graph shows the power curves intersecting at exactly the same speed as the wheel torque curves. This is guaranteed for any power curve by the mathematical relationship between power and torque. It is not a coincidence.

WebCharacteristic power–speed curves of two wind turbines. Some authors use analytic curves with linear, quadratic or cubic forms, or a combination of these, to represent the power curve PWT (v) of a wind turbine ( Haslett and Kelledy, 1981; Koeppl, 1982; Jones 1986, 1988; Celik, 2003; Chang and Tu, 2007). WebA variable speed wind turbine is one which is specifically designed to operate over a wide range of rotor speeds. It is in direct contrast to fixed speed wind turbine where the rotor speed is approximately constant. The reason to vary the rotor speed is to capture the maximum aerodynamic power in the wind, as the wind speed varies.
