ABSTRACT:
A turbine type synchronous motor capable of starting directly and asynchronously when coupled to a work-performing machine is constructed with a drum rotor of high mass, made of solid magnetic material containing iron, and having no damper winding. The field windings, short-circuited or closed through a resistance during starting, are radially disposed in insulated slots which are closed by insulated wedges wherein the insulation is of highly temperature resistant material.
