PURPOSE:To obtain an inexpensive fan guide mounting structure having good cooling efficiency by forming and integrating by pressing a fan guide from an end bracket. CONSTITUTION:A steel plate end bracket 103 formed integrally with a fan guide 102 is mounted by pressing on the end of a housing 101 for convering the outer periphery of an open type motor, and a hole punched at the fan guide 102 of the bracket 103 is used as an inlet hole 104 of cooling air. A stator 106 having a stator coil 105 is secured to the inner periphery of the housing 101, and a rotor 108 secured to a rotational shaft 107 through the prescribed gap is disposed inside stator 106. A cooling fan 109 is mounted on the end of the rotor 108. A plurality of cooling air outlets 110 are opened at the housing 101. |
