PURPOSE:To obtain necessary fixed voltage simply and broaden application by a method wherein a plurality of proper coils are selected among the coil groups of each phase, these coils are connected in series when connection and lead sections are mounted at both ends. CONSTITUTION:Proper coils are selected among the coil groups of each phase of polyphase armature winding. When coils U3, U4, V3, V4 are selected, the coil groups of each phase are Y-connected so that these coils are connected in series, and lead wires C1, C2 are mounted at both end sections of the selected coil group U3, U4, V3, V4. Fixed voltage smaller than line voltage is obtained from the lead wires C1, C2, and used for a power supply for a brake, a power supply for a lamp, etc. |
