The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors , power is delivered to windings in the stator (case) rather than the rotor . This simplifies mechanical design because power does not have to be delivered to the moving rotor, which eliminates the need for a commutator .
The short block would also have been built in a workshop that was hopefully cleaner and more organised for the specialism of engine building. Short blocks were OHV engines. Sidevalves were pre-eminent before the short block appeared as a common item, and they also offered little saving by omitting the (simple) head.
Bipolar toy motor of 1948. Note the three-pole rotor with a bipolar field. A bipolar electric motor is an electric motor with only two (hence bi-) poles to its stationary field. [1] They are an example of the simple brushed DC motor, with a commutator. This field may be generated by either a permanent magnet or a field coil.
Insides of a slip-stick piezoelectric motor. Two piezoelectric crystals are visible that provide the mechanical torque. [1]A piezoelectric motor or piezo motor is a type of electric motor based on the change in shape of a piezoelectric material when an electric field is applied, as a consequence of the converse piezoelectric effect.

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 ...
Scratch Drive Actuator A scratch drive actuator (SDA) is a microelectromechanical system device that converts electrical energy into one-dimensional motion. [ 1 ] [ 2 ]
The brush compound is compacted in a tool consisting of upper and lower punch and die, on mechanical or hydraulic presses. In this step, depending on later processing, the copper wire (called shunt wire) can be inserted automatically through a hole in the upper punch and fixed into the pressed brush block by the powder pressed around.
