Key Facts about Thyristor DC Motor Drives Operation
For motors up to a few kilowatts the armature converter draws power from either a single phase or 3-phase utility supply. For large motors, 3-phase power supply is preferred because the waveforms are much smoother although traction uses single-phase with … Read more

Back emf and Torque Equations of a DC motor
Single-loop motor The effect of the force in a magnetic field may be used to cause the rotation of a motor armature. A single loop of a conductor shown in the diagram above has its ends connected to a simple … Read more
