Bi-ventricular pacemaker â Maintains heart rate using synchronized pacing, or cardiac resynchronization therapy (CRT), that connects both the right and left ventricles; used to treat advanced heart failure; Implantable cardioverter defibrillator (ICD) â Monitors and paces the heart; delivers energy that restores the heart to a normal rhythm when it detects a dangerous rhythm; available in single-chamber, dual-chamber and bi-ventricular models.
The rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator. Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor's axis.
The two main parts of the induction motor are the stator, and the rotor. Stator in the induction motor is a series of concentric magnetic poles (usually electromagnets), and the rotor is a series of closed windings, or aluminium rods arranged in a way similar to a squirrel cage, hence the name squirrel cage rotor.
