Many versions of this DC shunt motor, with different power, voltage, and speed ratings, were produced by American company Crocker & Wheeler (C&W) in around 1900. In a shunt motor the field coils and armature windings are wired in parallel. In the early 20th century this relatively light type of motor was used for all sorts of applications, such as driving fans, sewing machines, and small bench tools. This motor is capable of providing one sixth horsepower at 1400 rpm, which is about 122 watts.
The DC electric motor has a length and height of 22 cm. The field coils are at the bottom, one on each side. Above that is the motor housing, which contains the armature. The pulley (the round disc) on the armature shaft at the right is for a drive belt. The commutator is on the left side. This converts the generated alternating current to direct current.
