The invention discloses a direct-current separately-excited motor controller. The direct-current separately-excited motor controller includes a shell, a supporting seat, a PCB and a bottom plate; the shell is a rectangular cover body; the bottom plate is a rectangular plate; the bottom end opening of the shell is fixedly connected with the bottom plate, so that a cavity can be formed; the front side plate of the shell is provided with a wiring terminal; radiating fins are uniformly distributed on the outer surfaces of the left side plate, the right side plate and the top plate of the shell; the PCB comprises a control circuit board and a main circuit board which are arranged along a vertical direction; the control circuit board and the main circuit board are respectively arranged at the upper end surface and the lower end surface of the supporting seat; the control circuit board and the main circuit board are fixed on the shell through connecting components; the supporting seat is fixedly connected with the front side wall, the back side wall, the left side wall and the right side wall of the shell; the control circuit board is attached to the inner surface of the top plate of the shell; the main circuit board is attached to the inner surface of the bottom plate; and a portion where the control circuit board is attached to the shell and a portion where the main circuit board is attached to the bottom plate are respectively provided with aluminum nitride heat-dissipation pins for heat dissipation.
Description
technical field [0001] The invention relates to the field of motor controllers, in particular to a DC separate excitation motor controller. Background technique [0002] In DC motors, according to the excitation method, it can be divided into separate excitation, series excitation, compound excitation and permanent magnet. As an important branch of DC motors, separately excited motors are widely used in industrial production. The most notable difference between the DC separately excited motor and other DC motors is that the armature coil and the excitation coil are powered by different power sources. It is precisely because of this excitation form that it has superior speed regulation performance and mechanical characteristics. [0003] The stability of the motor controller has always been a concern in the industry. For an excellent motor controller, a reasonable structural size and heat dissipation layout are essential. However, the current DC separately excited motor contr...
