In a typical motor, a component called a rotor turns inside a stationary component called a stator. One of those components contains permanent magnets that have south and north poles. The other has wire coiled around it. Putting electricity through the coils creates magnetic fields that attract and repel the poles of the permanent magnets.
Designing a motor to turn electricity into movement is tricky. In a typical motor, a component called a rotor turns inside a stationary component called a stator. One of those components contains permanent magnets that have south and north poles. The other has wire coiled around it.
In a hysteresis motor, however, it’s a useful mechanism. With careful controls, that lag in switching can cause the rotor—with its residual magnetization—to try to “catch up” with the present magnetic field of the stator; the rotor therefore turns with constant force, even when it’s first starting up.
