Automatic planer

The invention provides an automatic planer. The cooling efficiency of a controller can be further improved in the automatic planer. The automatic planer comprises a shell, a motor, a controller, a gasinlet, an exhaust port, a gas flow path and a fan, wherein the motor is accommodated in the shell; the controller is provided with a control base board for performing drive control of the motor; thegas inlet is formed in the shell; the exhaust port is formed in the shell; the gas flow path is arranged in the shell and configured so as to allow gas introduced from the gas inlet to flow through the motor toward the exhaust port; and the fan is used for generating gas flow flowing from the gas inlet to the exhaust port via the gas flow path. A specific region of the controller is disposed on the gas flow path. 提供一种自动刨床。在自动刨床中有助于控制器的冷却效率的进一步提高。该自动刨床具备：壳体；马达，其收容于壳体；控制器，其具有进行马达的驱动控制的控制基板；进气口，其设置于壳体；排气口，其设置于壳体；气体流路，其设置于壳体的内部，构成为能够供从进气口导入的气体经由马达朝向排气口流通；以及风扇，其用于产生从进气口经由气体流路而朝向排气口的气体流。控制器的特定区域配置于气体流路上。
