Problems solved by technology

[0002] Existing motor controllers such as figure 1 , figure 2 As shown, it includes box A, IGBT component B, gate plate C, driver board D, control board E and upper cover F. There is a cavity A1 in the middle of the box, and a cooling water channel A2 is opened on the bottom of the box. The IBGT component is installed on the bottom wall of the cavity and above the cooling water channel. The gate plate, driver board and control board are stacked and installed on the top surface of the IGBT component in sequence, and the upper cover is installed on the top surface of the box and covers the There is an opening at the top of the cavity, but this motor controller structure has the following disadvantages: 1) The modularity of the parts is low, and the scattered parts need to be installed in the box one by one, and the space inside the box is limited, so The installation is relatively troublesome and the efficiency is low; 2) The cooling effect of the motor controller is poor and unsatisfactory, which affects the stability and reliability of the equipment operation

Abstract

The invention discloses an IGBT (insulated gate bipolar transistor) module of a motor controller and an applied motor controller. The IGBT module comprises an IGBT element, a door pole plate, a driving plate and a control plate, wherein the door pole plate is mounted on a top face of the IGBT element, the driving plate is mounted on a top face of the door pole plate, and the driving plate is mounted on a top face of the driving plate. The IGBT module is characterized by further comprising a radiating bottom plate, a plurality of radiating fins are arranged on a bottom face of the radiating bottom plate and extend from top to bottom, a cool water channel is formed among the radiating fins, and the IGBT element is mounted on a top face of the radiating bottom plate. The IGBT module integrates the IGBT element, the door pole plate, the driving plate, the control plate and the radiating bottom plate, and is high in modularization degree and high in mounting efficiency for batch-production.
