Abstract

907,717. Electromagnetic brakes. ENGLISH ELECTRIC CO. Ltd. March 6, 1959 [March 13, 1958], No. 8081/58. Class 103 (1). [Also in Group XXXV] An electric motor 1 has an electromagnetically-released friction brake comprising an annular electromagnet having a plurality of armatures 5 which are arranged around the motor shaft or an extension thereof, pivotally mounted adjacent one end of the electromagnet, and have at their free ends friction surfaces urged into engagement with the shaft or its extension or a bush 2 secured thereto by a spring 10 acting on inturned lever portions 9 of the armatures. As shown, four armatures are pivoted against a thrust plate 6 and are guided to have only radial movement by a cruciform orifice in a ring 8. The force of the compression spring 10, conveyed via a chamfered plunger 11, is adjustable by movement of a shouldered screw 12 against which the spring is seated such adjustment being accessible by removal of a screw 16 securing the cover 15 of a terminal block 14 for the motor and brakewinding leads. The bush 2 may be of nylon, the armatures may have a lining of friction material, and the invention is applicable to electric remote-control systems in aircraft.
