A DC motor is a mechanically commutated electric motor powered from direct current (DC). The stator is stationary in space by definition and therefore so is its current. The current in the rotor is switched by the commutator to also be stationary in space. This is how the relative angle between the stator and rotor magnetic flux is maintained near 90 degrees‚ which generates the maximum torque. DC motors have a rotating armature winding but non-rotating armature magnetic field and a static field

GROUP 4 JULY 26‚ 2013 EE 4101 ENGR. KENNETH F. FAJILAN Reluctance Motor Introduction A reluctance motor is a type of electric motor that induces non-permanent magnetic poles on the ferromagnetic rotor. Torque is generated through the phenomenon of magnetic reluctance. There are various types of reluctance motor: Synchronous reluctance Synchronous reluctance motors have an equal number of stator and rotor poles. The projections on the rotor are arranged to introduce internal flux “barriers“

SISTEMAS DC Motors Catedrático: Ing. Gustavo Mendoza Leal Alumno: Alfredo Valdés Cárdenas Introduction A DC motor is a type of electrical machine that converts direct current into mechanical power by means of a magnetic field. DC motors are widely used in field applications because of their many advantages over AC motors such as speed control‚ high starting torque‚ quick starting‚ stopping‚ reverse and acceleration and free from harmonics found in AC. Applications of DC motors include but
