Période

THIS TYPE OF MOTOR PRESUMABLY USED LATE19TH-EARLY 20TH C.

Canada

THIS TYPE OF MOTOR USED IN CANADIAN CITIES AT THE TURN OF THE 20TH C. FOR ALL KINDS OF WORK REQUIRING STEADY SPEED. THE SOLE AGENT IN CANADA, UNTIL AT LEAST 1906, WAS PACKARD ELECTRIC CO. LTD. (REF. 1)

Fonction

TO CONVERT ELECTRICAL INTO MECHANICAL ENERGY.

Technique

THIS MOTOR IS A PERFECTED VERSION OF THE EARLIER CROCKER-WHEELER MOTOR. IT RAN WITHOUT SPARKING, WAS NOISELESS, AND WAS EQUIPPED WITH A CONTROLLING SWITCH. THE WIRE USED ON THE ARMATURE WAS LARGER, MAKING IT LIABLE TO BREAK. IT WAS EQUIPPED WITH AUTOMATIC CENTRIFUGAL SPEED GOVERNORS, SUITABLE FOR ALL KINDS OF WORK REQUIRING STEADY SPEED. THE CROCKER-WHEELER MOTOR WAS ALSO AN IMPROVEMENT OVER OTHER MOTORS BECAUSE THE CORE AND THE POLE PIECES WERE DROP-FORGED IN ONE PIECE AND EXACTLY TO SHAPE, TO PREVENT TOO MUCH MAGNETIC LEAKAGE. THE ARMATURE WAS MADE WITH TRAPEZOIDAL TEETH, MAKING THE MOTOR MORE EFFICIENT. THE BEARINGS WERE MADE OF THE BEST BABITT METAL, THE SAME AS IN THE LARGE STEAM ENGINES AND OTHER FIRST-CLASS MACHINERY. (REF. 1)
