1.maximum torque is experienced
2.torque is uniform for all positions of coil
A radial magnetic field is one in which the plane of the coil is always parallel to the direction of the magnetic field. The main advantages of the armature to rotate in a radial magnetic field than uniform one are: 1. The maximum torque is generated 2. For all positions of a moving coil, torque is constant.
If the diametrical clearance cannot be measured directly, the radial clearance can be calculated using the formula: Radial Clearance = (Diameter of the larger part - Diameter of the smaller part) / 2 This formula assumes that the parts are concentric and that the radial clearance is uniform around the circumference.
The magnetic field inside a current-carrying loop is uniform near the center of the loop and perpendicular to the plane of the loop. As you move away from the center, the field strength decreases and the direction of the field may not be completely uniform due to the loop's geometry.
A horseshoe electromagnet is used to generate a magnetic field when an electric current passes through it. It is commonly used in various applications such as in electric motors, speakers, and magnetic resonance imaging (MRI) machines. The horseshoe shape helps concentrate and strengthen the magnetic field produced.
A thrust bearing is designed to handle axial loads (parallel to the shaft), while a radial bearing is designed to handle radial loads (perpendicular to the shaft). These bearings have different internal structures to accommodate their respective load types. Thrust bearings usually have a series of balls or rollers to support axial loads, whereas radial bearings have a raceway to support radial loads.
In uniform circular motion, "uniform" refers to a constant speed of the object moving in a circular path. It means the object is moving around the circle at a consistent rate without speeding up or slowing down. uniform circular motion does not mean that the object is at rest or that the path is a perfect circle.
1. to intensify the magnetic field by reducing the length of airgap across which the magnetic flux has to pass; 2. to give a radial magnetic flux of uniform density, thereby enabling the scale to be uniformly divided.
A radial magnetic field ensures that the plane of the coil (rotating within the magnetic field, in say a DC motor) is always flat within the external magnetic field ensuring maximum torque in (nearly) all positions. Hope this helps!
To provide a radial magnetic flux.
A motor effect is when magnetic flux lines interact with the current flow in the current conducting wire (a production of current means there is a production of a magnetic field, thus the magnetic field of a permanent magnet interacts with the magnetic field of the current), hence causing a motor effect, where electric energy is transformed into mechanical energy. In a galvanometer, the concept of the motor effect is used for it to detect and measure the magnitude of small electric currents as an instrument. A galvanometer uses radial magnets which cover more area of the rotor (this is where the needle is attached), as this rotor consists of an armature and loops of wire, it is perpendicular to the magnetic flux lines of the radial magnet. Therefore as the current flows through the coil, a magnetic field is produced, and the motor effect occurs allowing the needle to move on the scale.
When a centrifugal pump operates at its best efficiency point (BEP), the flow angles match with the impeller vane angles. At the BEP, the flow velocity in the volute is uniform around the volute (i.e., there is not acceleration of the fluid in the volute). Therefore, the pressure around the volute is uniform. The uniform pressure around the circumference results in a net zero radial force on the impeller (or the shaft). Note this is theoretical. In practice even at BEP, there is a small radial load because the pressure is not uniform. If the pump is operated away from the BEP, the flow velocities in the volute are non-uniform which results in a non-uniform pressure field and a net radial load (can be obtained by integrating the pressure around the circumference of the volute or the impeller).
That would be a TWT amplifier (traveling wave tube).
To produce a constant torque on the coil
It's far better to have the armature re-wound by a specialist repairer. Trying to repair reliably, a break of wire or insulation in a tightly-wound armature revolving within a stator with very little radial clearance,is not really feasible; and certainly not easy. To be honest I'd look at a new machine if possible, by exchange if available.
Radial symmetry is selectively advantageous because the organisms approach their environment from all sides equally. In addition to sessile animals, radial symmetry can also be found in some other animals and plants.
