The motor from a 3.5 in floppy disk drive. The coils, arranged radially, are made from copper wire coated with blue insulation. The rotor (upper right) has been removed and turned upside-down. The gray ring inside its cup is a permanent magnet. This particular motor is an outrunner, with the stator inside the rotor. DC brushless ducted fan. The ...
The features of a radial flux motor are placed on the sides. The copper windings are wrapped around slots. [1] A traditional radial flux BLDC motor places a rotor made of permanent magnets inside the stator. The stator contains support known as a yoke, which is outfitted with "teeth", individually wrapped with electromagnetic coils.
JMAG was originally released in 1983 as a tool to support the design of devices such as motors, actuators, circuit components, and antennas. JMAG incorporates simulation technology to accurately analyze a wide range of physical phenomena that include complicated geometry, various material properties, structure at the center of electromagnetic ...
When performing a modeling task for any accelerator operation, the results of charged particle beam dynamics simulations must feed into the associated application. Thus, for a full simulation, one must include the codes in associated applications. For particle physics, the simulation may be continued in a detector with a code such as Geant4.

Permanent-magnet types have some performance advantages over direct-current, excited, synchronous types, and have become predominant in fractional horsepower applications. They are smaller, lighter, more efficient and more reliable than other singly-fed electric machines. [2] Originally all large industrial DC motors used wound field or rotor ...
The motor speed varies as a non-linear function of load torque and armature current; current is common to both the stator and rotor yielding current squared (I^2) behavior [citation needed]. A series motor has very high starting torque and is commonly used for starting high inertia loads, such as trains, elevators or hoists. [2]
The Lynch motor is a unique axial gap permanent magnet brushed DC electric motor. [1] The motor has a pancake-like shape and was invented by Cedric Lynch in 1979, the relevant patent being filed on 18 December 1986.
