An industrial electric motor . An electric motor is a machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.
Fleming's left-hand rule. Fleming's left-hand rule for electric motors is one of a pair of visual mnemonics, the other being Fleming's right-hand rule for generators. [1] [2] [3] They were originated by John Ambrose Fleming, in the late 19th century, as a simple way of working out the direction of motion in an electric motor, or the direction of electric current in an electric generator.
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. [1] It is a commutated series-wound motor where the stator's field coils are connected in series with the rotor windings through a commutator. It is often referred to as an AC series motor.
The large brown molded-plastic piece in the foreground supports the brush guides and brushes (both sides), as well as the front motor bearing. A field coil is an electromagnet used to generate a magnetic field in an electro-magnetic machine, typically a rotating electrical machine such as a motor or generator.
Barlow's wheel was an early demonstration of a homopolar motor, designed and built by English mathematician and physicist, Peter Barlow in 1822. [1] It consists of a star-shaped wheel free to turn suspended over a trough of the liquid metal mercury , with the points dipping into the mercury, between the poles of a horseshoe magnet .

The DIII-D tokamak at General Atomics, the Princeton Large Torus (PLT) at the Princeton Plasma Physics Laboratory, and the Nimrod synchrotron at the Rutherford Appleton Laboratory each used large flywheels on multiple motor–generator rigs to level the load imposed on the electrical system: the motor side slowly accelerated a large flywheel to ...
