What type of DC motor has relatively low starting torque, but has excellent inherent speed regulation?
AI Explanation
The correct answer is D) shunt wound.
Shunt wound DC motors have relatively low starting torque, but excellent inherent speed regulation. This is because the field winding is connected in parallel (shunt) with the armature winding, which allows the field current to remain relatively constant regardless of load changes. This constant field strength provides the motor with good speed regulation, even as the load varies.
In contrast, series wound motors have high starting torque but poor speed regulation, while compound wound motors and permanent magnet motors have characteristics that fall between the series and shunt wound types.
