The Hodson Motor Kit is supplied as a pack of 2x kits (packed in strong jars).
It allows the student to wind his/her own electric motor and to make the brushes required to run it. Knowledge comes from the exercise of winding the motor and predicting results.
The finished motor holds together well so an assembled sample can always be kept in the classroom to aid beginners.
The motor can run as either a DC motor from a battery or as a synchronous AC motor from an AC power source. The kit provides everything required, except for the 'D' cell battery, but there is room for a battery to be stored in each kit.
