Abstract

The invention provides a motor drive device (20), which comprises a flange (25) and a radiator (30) combined with the flange. In addition, the device also comprises a fan motor (55) for cooling the radiator and a fan unit (50) equipped with a setting member (52) for the fan motor. The fan unit is fixed to the fixing part (56) of the motor drive device. The fan unit extends perpendicularly from the radiator in the insertion direction of the a second opening part (16). An abutting part (49) abutting against the front end of the setting member or a cooperation part (48) cooperating with the front end of the setting member is provided. Therefore, noises are avoided and cooling performance is prevented from decreasing. The fan motor can also be replaced and tested.

Description

technical field [0001] The present invention relates to a motor drive device including a fan unit for cooling a radiator mounted on a motor drive unit. Background technique [0002] A heat sink for heat dissipation is attached to the motor drive device installed inside the control panel. In addition, the fan unit provided with the fan motor is provided on the radiator, thereby improving the cooling effect. [0003] Japanese Patent Application Laid-Open No. 09-065661 discloses a structure in which a radiator is arranged behind a motor drive unit and a fan motor is directly fixed to the radiator. In addition, the fan motor can also be arranged near the radiator. [0004] Typically, the rear of the motor drive is located on the back of a control panel disposed adjacent to a wall or other device. Therefore, it is difficult to access the fan motor from the rear side of the motor drive device to replace and inspect the fan motor. Therefore, it is necessary to temporarily remov...
