Select all that are true. Group of answer choices major parts of a dc motor are stator, rotor, commutator, and brushes. If the rotor of a dc motor consists of just one conductor loop, the output torque will vary in magnitude from zero to a maximum and back to zero over every half turn of the rotor. Using multiple loops in the rotor of a dc motor not only gives higher torque but also ensures a constant magnitude of the output torque. Using electromagnets in the stator of a dc motor makes higher torque values possible. In a series motor, rotor and stator are connected in series. In a shunt motor, a bypass circuit is provided to prevent overload.
