Is a Permanent Magnet Motor Feasible? | Power Electronics

A permanent magnet motor would not produce energy and would not be a perpetual motion machine Instead, it would simply use the electromagnetic energy delivered by the angular momentum of the electron in the form of magnetic forces Although quantum physics has described angular momentum as the source of energy, there remain some scientists and lay people who hold onto the incorrect

Parts of a Winch Explained – Motor Types, Gear Types

Winches use two types of DC motors, Permanent Magnet Motors and Series Wound Motors All electric DC winch motors consist of one set of coils, called an armature, inside another set of coils or a set of permanent magnets, called the stator It is the job of the stator to produce a magnetic field which will cause the rotor (or armature) to rotate when an electric current flows through it

Permanent Magnets

Coercivity and Remanence in Permanent Magnets A good permanent magnet should produce a high magnetic field with a low mass, and should be stable against the influences which would demagnetize it The desirable properties of such magnets are typically stated in terms of the remanence and coercivity of the magnet
