Electric Motors

An electric motor is a machine that converts electrical energy into mechanical energy.

An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor that produces torque is obtained by electromagnetic induction from the magnetic field of the stator winding.

A synchronous electric motor is an AC electric motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current.

A stepper motor, also known as step motor or stepping motor, is a brushless DC electric motor that rotates in a series of small and discrete angular steps.

A linear motor is an electric motor that has had its stator and rotor "unrolled", thus it produces a linear force along its length, rather than a rotational force (torque).

A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply.

The switched reluctance motor (SRM) is a type of reluctance motor.

A servomotor (or servo motor or simply servo) is a rotary or linear actuator that allows precise control of angular or linear position, velocity, and acceleration in a mechanical system.

The shaded-pole motor is the original type of AC single-phase electric induction motor, dating back to at least as early as 1890.

A torque motor is a specialized form of DC electric motor which can operate indefinitely while stalled, without incurring damage.

An electrostatic motor or capacitor motor is a type of electric motor based on the attraction and repulsion of electric charge.

The universal motor is a type of electric motor that can operate on either AC or DC power and uses an electromagnet as its stator to create its magnetic field.

A DC motor is an electrical motor that uses direct current (DC) to produce mechanical force.

An axial flux motor (axial gap motor, or pancake motor) is a geometry of electric motor construction where the gap between the rotor and stator, and therefore the direction of magnetic flux between the two, is aligned parallel with the axis of rotation, rather than radially as with the concentric cylindrical geometry of the more common radial flux motor.

A repulsion motor is a type of electric motor which runs on alternating current (AC).

A wound-rotor motor, also known as slip ring-rotor motor, is a type of induction motor where the rotor windings are connected through slip rings to external resistance.

A reluctance motor is a type of electric motor that induces non-permanent magnetic poles on the ferromagnetic rotor.
