![]() ![]() When the load is extremely low within a shunt motor, then the armature current can also be below. As a DC Shunt motor attains its complete speed, then the armature current can be directly connected to the motor load. The speed characteristic of a shunt motor is different compared with a series motor. of parallel lanes DC Shunt Motor Speed Control N = Motor’s speed in revolutions per minuteĪ = No. Mathematically, this can be expressed as, Thus, this e.m.f is named as the back e.m.f, & it is represented with Eb. Although, according to Lenz’s law, the induced e.m.f can act within reverse direction toward the armature voltage supply. Thus an e.m.f can be stimulated within the armature winding based on the Faradays law ( electromagnetic induction). Whenever the DC shunt motor’s armature winding rotates within the magnetic field which is generated by the field winding. Thus the Φ remains more otherwise less stable, due to this reason a shunt wound DC motor can be named as a constant flux motor. But we know that the armature current is proportional to the field flux (Ish ∝ Φ). ![]()
