Abstract

1,048,471. Commutation arrangements for dynamo-electric machines. MINISTER OF AVIATION. Oct. 19, 1962 [July 19, 1961], No. 26136/61. Heading H2A. A motor having a permanent magnet rotor M has the stator field windings commutated by means of light-sensitive devices, e.g. phototransistors, sequentially excited from a light source through a rotating shutter. Pairs of photo-transistors R +, R - ; B+, B-; G +, G - ; are supported in radial pairs spaced 120 degrees apart around the axis of the machine with the positive ones illuminated through slot P and the negative ones through slot N. As the shaft rotates the stator windings of the motor are connected in turn to the positive or negative supply lines depending on which transistor is illuminated, or effectively disconnected when neither transistor is illuminated, thus producing a rotating field vector. The transistors may either switch the stator windings directly or be used to actuate further high power electronic switches depending on the size of the motor.-The motor is readily reversible. Reference has been directed by the Comptroller to Specification 973,797.
