Cumulative and differential compound motors
WebA typical characteristic is shown in Fig. 1.19. In a differentially compound motor the air gap flux decreases with load, causing an increase in the speed as load increases. There may be no saturation effects. The armature reaction demagnetises the air gap flux causing a further increase in speed. It is less stable than a cumulatively compound ... WebSpeed current characteristic of cumulative DC compound motor at larger values of armature current is similar to that of _____ DC shunt motor Induction motor DC differential compound motor DC series motor. dc machines Objective type Questions and Answers.

WebThe connection diagram of the compound motor is shown below. The compound motor is further subdivided as cumulative compound motor and differential compound motor. Cumulative compound motor: In a cumulative compound motor, the flux produced by both the windings is in the same direction. It provides high starting torque; Good speed … WebIn cumulative compound motors, the series field aids the shunt field, so flux per pole increases as the armature current increase and hence speed decreases. ... In a differential compound motor, the motor speed will increase with an increase in the load, which leads to an unstable operation.
Compound motors can be divided into two major categories based on the way their field winding is connected to the armature winding and which are Long Shunt and Short Shunt. In the following section, we delve deeper into both of these categories.
