[Problem] To improve workability during brake installation. [Solution] A motor (100) has: a rotor (9) that is provided on a rotary shaft (3); a stator (10) that is positioned in the radial direction so as to face the rotor (9) via a magnetic space; a counter-load-side bracket (6) on which a counter-load-side bearing (8) for supporting the rotary shaft (3) is provided; a field core (12) that houses a coil (19), and is fixed to the counter-load-side bracket (6) by means of a bolt (31); multiple cylindrical collars (33) that are inserted into the counter-load-side bracket (6) at one end, and are positioned between the couner-load-side bracket (6) and the field core (12); an armature (13) that is supported so as to be capable of moving in the axial direction of the rotary shaft (3) with respect to the field core (12), and has notches (34) for engaging with the collars (33) on the periphery thereof; and a brake disc (15) that is fixed to the rotary shaft (3), and with which the armature (13) frictionally engages. |
