The Holtzer-Cabot Electric Co. has recently placed onthe market a line of single-phase, seU-starting inductionmotors of the split phase type. These motors are character-ized particularly by compactness, ruggedness and excellentstarting and running properties. As these motors require onlya double pole switch for controlling them, it is impossible todamage them by opening or closing the switch at any partof the starting cycle and they are particularly adapted to becontrolled from a V2-b-P- Single-Phase Motor

The compactness obtained in designing these motors enablesthem to be used in many places where there is not room torlarger motors. The shafts and bearings, however, are un-usually large. Every effort has been made to avoid compli-cations likely to cause trouble. Mechanically the motors fol-low the type established by polyphase practice the worldover. The rotors are of the simple squirrel cage typewithout any combustible insulation whatever, and are there- 0 6 6 ^ ?== ?^ ^ a ^ -o—a ,/ ^ J r 0. zu / y TVpe.

No friction clutch, commutator or revolving wind-ing is necessary to enable the load to be started. The electrical properties of these motors are particularlygood for single-phase machines, as may be seen from theacc
