摘要： A motor frame with bumps includes a frame body, plural bumps and plural heat-dissipation fins. The frame body has an internal surface and an external surface. Each of the bumps protrudes radially inward from the inner surface, and plural internal flow passages are formed by every two neighboring bumps. Each of the heat-dissipation fins protrudes radially outward from the external surface, and plural external flow passages are formed by every two neighboring heat-dissipation fins. Each of the bumps is radially outwards respective to at least two of the heat-dissipation fins.
