WebWith this method, four different speeds can be obtained 1. when only motor A works, corresponding speed = .Ns1 = 120f / P 1 2. when only motor B works, corresponding speed = Ns2 = 120f / P 2 3. if commulative cascading is done, speed of the set = N = 120f / (P 1 + P 2) 4. if differential cascading is done, speed of the set = N = 120f (P 1 - P 2) 3. WebThe maximum range of speed control of about 3 : 1 will be available depending on the load. This method of speed control is most economical for constant torque drives. This method of speed control is employed chiefly for dc series motors driving cranes, hoists, trains etc. because such drives operate on intermittent duty. proximity badge
