Abstract
A coreless permanent-magnet DC motor is characterized by comprising a commutator (1), a rear cover (2), a brush (3), a coreless armature coil (4), an external stator (6), an internal stator (7), and a rotary shaft (8). The rotary shaft (8) is rotatably connected to the internal stator (7) which is externally connected to the external stator (6). The commutator (1) is fixed on one end of the rotary shaft (8), and is connected to the brush (3) which is fixed on the rear cover (2) connected to the external stator (6). The coreless armature coil (4) is cylindrical in shape. Because of absence of an iron core, dissipation and rotation inertia are reduced, and force and energy index and efficiency are high. By using a coreless V-shaped inclined winding coreless armature, the coreless permanent-magnet DC motor has advantages of small volume, light weight, fast reaction, rapid starting, high motor efficiency, stable operation, low noise, high reliability and the like, and benefits rapid wire wrapping.
