PMDC motor offers ___________(a) Cumulative compound type characterist

1.	PMDC motor offers ___________(a) Cumulative compound type characteristic(b) Differential compound type characteristic(c) Series characteristic(d) Shunt characteristicI have been asked this question in an international level competition.I'd like to ask this question from PMDC Motors topic in section DC Machines of DC Machines
Answer» Right OPTION is (d) Shunt characteristic Easiest explanation: The stator is made of permanent magnet in the PMDC motor hence, there is no NEED for separate FIELD excitation for stator. So, PMDC acts as a shunt motor with FIXED field. This can be seen from the construction also.
