Abstract

The stepping motor esp. for an electric clock, has a stator (1) with an arm (2) on which the excitation coil assembly (3) fits. The coil assembly comprises a coil (5) and a coil former (4). The stator is divided into two parts: the first break (26) being across the arm inside the coil assembly and the second break (27) being near a corner outside the coil assembly. Both breaks are at an angle. The stator can therefore be easily assembled and held together by a socket (14) enclosing the second break. Retaining devices (15,16,19) prevent the stator rotating and moving axially. The socket has a locking spring (30) acting in a direction that holds the two stator parts together.
