Hamburg-Blankenese-Ohlsdorf Railway Improvements—Two Views of the New Single-Phase Motor by the alternating magnetic field in the armature coilsshort circuited under the brushes. At the same timethese interpoles also give a component field to take up thecommutation voltage which occurs in a single-phase justas in a direct-current motor. The electrical qualities ofthis motor permit larger air gaps than hitherto withoutaffecting the efficiency. The stator winding has six mainpoles, each of which consists of three coils. There arc threecommutating poles for the six main poles. The armature control, lighting, compressor and heating circuits. Themain low-tension coil is grounded and also has an auto-matic cut-out to prevent abnormally high potentials. Themotormans cab contains an oil switch which has one con-nection on each side to a grounding switch. When thedoor of the high-tension compartment is opened this switchimmediately grounds all apparatus therein through a cop-per bar which is
