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.
Motor is commonly thought to only be electric, which of course, converts electric energy to mechanical energy. But, that is only an electric motor. Motor; a machine, especially one powered by electricity (e.g. electric motor) or internal combustion (e.g. engine), that supplies motive power for a vehicle or for some other device with moving parts. An engine is a motor that converts thermal energy to mechanical work (more simply, a machine with moving parts that converts power into motion).
