why onlyseries motors are used as universal motors? why not
shunt?

Answer Posted / qureshi majid

Shunt motors are started directly through line,which may be
damaging to the armature and they need special starter
avoiding said damage,where as series motors have high
starting torque with load.without load, starting must be
avoided because empty running can get very high speed
exceeding limit may cause serious damage to the system .
