One kind of the outdoor fan drive apparatus that comprises: before the driving of the outdoor fan of the brushless motor starter, the device may be determined according to the rotational direction of the output signal of the brushless motor a rotor position detecting means for detecting the rot...
A new form is suggested of writing the kinetic coefficients, which agrees with the derivation of the kinetic equation and includes the Markov definition as a special case. Relations are established between the kinetic coefficients with conditional moments and cumulant functions of the random process. ...
