The invention provides a motor with a brake, a drive device, and a wheel drive device. The outer peripheral surface of the stator is fixed to the inside in the radial direction of the cylinder portion, and the stator has a through hole in the axial center portion. The rotor is arranged on the inner side of the cylinder part in the radial direction in a relative rotation mode. The rotating shaft is inserted into the through hole of the stator. The pair of circular plates is provided on both sides in the axial direction of the stator, and the pair of circular plates is coupled so as not to rotate relative to the rotating shaft and so as to be slidable in the axial direction. The magnet is fixed to the end face, opposite to the stator, of the two axial end faces of the circular plate. The pressing member is disposed on the outside in the radial direction of the rotating shaft, and is inserted into the through hole of the stator. The pair of friction plates is located between the first cover portion and the disc plate disposed on one side in the axial direction of the stator, and between the second cover portion and the disc plate disposed on the other side in the axial direction of the stator.
本发明提供带制动器的马达、驱动装置以及车轮驱动装置。定子的外周面固定于筒部的径向内侧,所述定子在轴心部具有贯通孔。转子以可相对旋转的方式设置于筒部的径向内侧。旋转轴被插入于定子的贯通孔中。一对圆板设置于定子的轴向的两侧,并且该一对圆板以不能相对于旋转轴相对旋转并且能够沿轴向滑动的方式结合。磁铁固定于圆板的轴向的两端面中的与定子相对的端面。按压部件配置于旋转轴的径向外侧,并且被插入于定子的贯通孔中。一对摩擦板位于被配置于定子的轴向的一侧的圆板与第1盖部之间以及被配置于定子的轴向的另一侧的圆板与第2盖部之间。
