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.
Rotors (A) are the biggest brake component you will see. They are a circular plate mounted to your axle, surrounding the hub (E). The rotor is what the brake pads clamp to in order to stop the vehicle. Brake pads (D) are the actual pieces that clamp to the rotors to do the stopping.
