Abstract

PURPOSE:To reduce the number of components by providing a brake core having an exciting coil by placing together with it in the advanced direction of a stator core of a motor and using a permanent magnet and a back core both as a motor and a brake gear. CONSTITUTION:A brake gear 1, when the length in the advanced direction of a core 5(a) of a stator 5 of a linear DC motor is Lm, is placed to the stator core together with a brake core 10(a) having a U-section as the length (Lm>Lb) of the same width Lb that it has. And, the center part S of the brake core 10(a) as well as the stator core 5(a) is opposed to a permanent magnet 6 at a distance of gap g2, and both ends T thereof are constituted so as to oppose to a back core 7 at a distance of gap g1. Accordingly, in the time of normal operation, a coil 10(c) is excited by power closing operation, and a brake is released so that a linear DC motor 1 makes a specific operation. At this time, even if electrical power fails, the excitation of the coil 10(c) is cut off and an emergency brake is applied to the motor 1.
