WebAug 22, 2024 · The power loss or FR loss that occurs due to current flow through the resistance of the various windings of the motor is termed as copper loss. In a dc motor, it takes place in the armature and field circuits. Generally, armature copper loss is about 30 to 40% and field copper loss is about to 20 to 30% of full-load losses. WebDec 4, 2016 · Mechanical losses. As their name suggests, mechanical losses are caused by movement of the motor. These include the friction in the motor bearings, friction between the brushes and the commutator, and drag on the rotor caused by turbulence of the air around it (sometimes referred to as windage loss). Mechanical losses increase with …

Other types of DC motors require no commutation. • Homopolar motor – A homopolar motor has a magnetic field along the axis of rotation and an electric current that at some point is not parallel to the magnetic field. The name homopolar refers to the absence of polarity change. Homopolar motors necessarily have a single-turn coil, which limits them to very low voltages.

WebMar 31, 2024 · A shunt is a thin tube that drains away the extra CSF from the ventricles of the brain, to other parts of the body, where it is absorbed. Shunts are usually plastic and small, about 0.3cm (3mm) across. They have valves so that fluid can flow down from the brain but not back the other way. Shunts are also called ventricular catheters. WebA shunt is a hollow tube surgically placed in the brain (or occasionally in the spine) to help drain cerebrospinal fluid and redirect it to another location in the body where it can be reabsorbed.
