The characteristic Curve of the motor is made of four performance lines:N=f(T) (rotational speed – torsion line), I= f(T) (electric current – torison line), P=f(T) (output power – torison curve), η=f(T) (efficiency – torsion curve)
No in the chart represents the unloaded rotational speed (r/min),which refers to the number of times the motor rolate every minute under specified voltage without any load.
Io in the chart respesents unloaded the electric current(A), which refers to the electric current value of the motor under specified voltage without any load.
Ts in the chart respesents standstill torsion (g.cm),which refers to the torison which stops the motor rotating under specified voltage.
Is in the chart respesents standstill electric current(A), which refers to the electric current value when the torsion stops the motor rotating specified voltage.
P in the chart respesents output power of the motor(W).
Pmax in the chart respesents the maximum output power of the motor.
η in the chart respesents the working efficiency of the motor (%), which refers to the output power x100%.
η max in the chart respesents the the maximum efficiency of the motor.
