Période

THIS TYPE OF MOTOR USED C.1894-1924

Canada

PART OF A LARGE AND VARIED COLLECTION OF ELECTRICAL ITEMS ACQUIRED & DOCUMENTED BY ONTARIO HYDRO IN THE 1960S. THIS COLLECTION CONSISTS OF OVER 7500 ARTIFACTS, AND IS THOUGHT TO BE THE LARGEST & MOST COMPREHENSIVE IN CANADA. IT WAS DONATED IN ITS ENTIRETY TO THE NATIONAL MUSEUM OF SCIENCE & TECHNOLOGY IN 1992

Fonction

TO CONVERT ELECTRICAL ENERGY INTO ROTARY MECHANICAL ENERGY

Technique

VERY EARLY WESTINGHOUSE DESIGN FROM WHICH INDUCTION MOTOR PRINCIPLES WERE DEVELOPED, AND LATER, MORE ADVANCED DESIGNS FOLLOWED. TYPE B MOTORS FEATURED AN IMPROVED SECONDARY WINDING (FIELD ASSEMBLY), WHICH COMBINED RESISTANCE STARTING WITH THE EFFECTS OF A CAGE WINDING AT FULL SPEED. A CLOSED-COIL, SERIES TYPE WINDING OF LOW VOLTAGE, WAS USED IN THE SECONDARY, WITH NUMEROUS IRON GRIDS CONNECTED BETWEEN ADJACENT COILS. AS FULL SPEED WAS ATTAINED, A SHORT CIRCUITING RING, SURROUNDING THE SECONDARY WINDING WAS SHIFTED CIRCUMFERENTIALLY TO BRING IT INTO CONTACT WITH THE SECONDARY BAR END CONNECTORS AT A LARGE NUMBER OF POINTS. THIS MOTOR WAS VERY SUCCESSFUL, BUT IT WAS EXPENSIVE TO BUILD AND THE DESIGN PRESENTED SOME LIMITATIONS, RE: VOLTAGE (REF.1)
