PROBLEM TO BE SOLVED: To provide a motor whose installation space can be reduced and whose connecting operation can be made easy by a method in which components for a driving device such as an inverter or the like used for a driving control operation are built in so as to be distributed to a plurality of components for the motor. SOLUTION: A rectifying circuit 16 and a smoothing capacitor 17 as components for an inverter 15 are connected so as to be built in a terminal box 14 as a component for a motor, and connecting terminals 27 which are used to connect input power supplies U, V, W are installed at the rectifying circuit 16. On the other hand, a switching circuit 18 as another component for the inverter 15 is built in a bearing bracket on the side of a fan as another component for the motor, and a drive circuit part 26 as another component for the inverter 15 is built in a fan cover as another component for the motor. Thereby, the installation space of the motor can be reduced, and the connecting operation of the motor can be made easy. |
