INTERPOLE RAILWAY MOTOR ON AXLE. wheels 950 mm. ( ins.), and the maximum speed of thecars is 70 km. ( miles) an hour. This motor has fourmain and four auxiliary poles. The former are laminated,and, while the latter are solid, they are slotted in a planeperpendicular to the axis to avoid eddy currents. Thearmature current flows through both sets of windings; areversal in the direction of running causes a simultaneousreversal in both the primary and secondary windings. The Works have also built an interpole motor with anhourly rating of 160 hp at 630 and 1000 volts. This
