A DC shunt motor is a type of direct current (DC) motor in which the field winding is connected in parallel (shunt) with the armature winding. Because the field winding is connected directly across the supply voltage, the field current …

The developed torque of a DC motor is the torque produced due to the interaction between the magnetic field of the stator and the current-carrying conductors of the armature. This electromagnetic interaction converts electrical energy into mechanical energy, causing the …

A DC series motor is a type of direct current (DC) motor in which the field winding is connected in series with the armature winding. Because of this series connection, the same current flows through both the armature and the …
