<p>The stator is made in two parts and it is provided with pole fingers. It supports the winding. A helical spring (9) is provided at one end of rotor shaft (2) between the rotor (1) and a bearing (8) installed in the motor casing (6). It presses the rotor against the other bearing (10) in the second part of the casing (7), so that the rotor (1) is slightly braked; its oscillations are consequently nearly aperiodically damped at the end of a current pulse, and a greater stepping-speed a more flexible pulse variation and a more steady run are achieved.</p> |
