Abstract
An educational electric motor adapted to be easily assembled and disassembled, comprising a three-part case formed from a central magnetic body connected at each end with transparent front and rear covers. Tape or clamping members are used to connect together the three-part case. An assembled rotor may be easily fitted within the motor case to rotate therein. A current feeding member is removably secured to at least one of the covers. The motor may be readily assembled by children and the transparent components permit the underlying principles of electricity and operation to be readily grasped and learned.
