Abstract

The invention provides a cooling plate for electric motor with improved heat radiation capability. The cooling plate includes a plurality of plate members stacked on one another between an electric motor and a coupled body to which the electric motor is coupled, wherein at least one of the plurality of plate members has a penetration groove extending through the plate member in a thickness direction and extending in the plate member in a plane direction orthogonal to the thickness direction, the penetration groove defining a coolant supply channel for supplying a coolant.

Description

technical field [0001] The invention relates to a motor cooling plate for cooling the heat generated by an electric motor. Background technique [0002] In a machine using an electric motor, such as a machine tool, the heat generated by the electric motor is transmitted to other parts of the machine through the connecting portion of the electric motor. Depending on the location of the machine, there is a large thermal deformation caused by the heat generated by the motor, which cannot be ignored, and as a result, the processing accuracy may be reduced. In contrast, there is known a technique of interposing a cooling plate between the motor and other parts of the machine to reduce heat conduction from the motor (see JP-A-2011-51027). [0003] A motor cooling plate that effectively reduces heat transfer from the motor is desired. Contents of the invention [0004] According to a first aspect of the present invention, there is provided a cooling plate, which is composed of ...
