Starters are used with D.C. motors because to restrict armature current as there is no back e.m.f. while starting.
Last Answer : D.C. shunt motors are used for driving machine tools.
Description : State starters used for i) 3-Ph squirrel cage induction motor (3HP) ii) D.C. motor
Last Answer : Name the starters used for following motors : i) 3 H.P. 3-Ph squirrel cage I.M: i) DOL starter OR ii) Star-Delta Starter OR ii) Auto transformer starter OR iii) Soft start starter. ii) D.C Shunt Motor : 1) Armature resistance starter (Three Point Starter) OR 2) Four Point Starter
Last Answer : In case of D.C. shunt motors the speed is dependent on back e.m.f. only because flux is practically constant in D:C. shunt motors.
