Problems solved by technology

One is that the power module generates a lot of heat, and the service life of the electronic device is shortened by half when the temperature of the electronic device rises by 10°C; the other is that the power module has more pins than conventional electronic components, and the slightly larger vibration during its installation and use may cause stress Active pin causes failure
However, it is difficult to avoid these two problems when the power module is applied to the motor controller.
The usual practice in the industry is to separately design the radiator and controller and add a vibration damping device or structure to prevent excessive temperature and excessive vibration, but the increase in the structure will lead to an increase in the size and cost of the motor

Embodiment Construction

[0013] figure 1 It is an embodiment in accordance with the technology of the present invention, wherein the motor 100 includes a stator 110, a rotor (not shown), a front end cover 130 for fixing the relative rotation of the stator and the rotor, a rear end cover 140, and a controller 150 fixed on the end cover. The front and rear covers (130, 140) are metal parts, and in this embodiment, aluminum alloy is used for casting. The controller 150 can be fixed on any end cover according to design requirements, but in this embodiment, the controller 150 is fixed on the rear end cover 140 of the non-output end of the motor. The controller 150 is a PCB board 170 that integrates the power module 160 and other conventional electronic components (capacitors, inductors, terminals, etc.), wherein the power module (160) and the conventional electronic components are located on both sides of the PCB board 170, respectively. In this embodiment, the side of the PCB board 170 on which the power...

Abstract

The invention discloses a motor of an integrated controller and an installation method thereof. The motor of the integrated controller comprises a stator, a rotor, a first end cover for fixing the stator and the rotor to move relatively, a second end cover made of metal materials with good thermal conductivity and a controller, a PCB of the controller configured with a power module and conventional electric elements, the power module and the conventional electric elements of the controller are located at the two sides of the PCB respectively, and the power module configured on the PCB is fixed on the second end cover in an attached mode. The power module conducts heat radiation through using the second end cover, the cost of independently arranging a radiator is saved, and the power module can be effectively fixed on the PCB.

Description

technical field [0001] The invention relates to a motor with an integrated controller and an installation method thereof, in particular to a controller-controlled motor with a power module and an installation method thereof. Background technique [0002] Traditional motor manufacturers only provide stator and rotor solutions for customers to choose from, and customers need to design or purchase corresponding control devices separately. Since the overall cost of the motor solution is very high due to separate design or procurement, and the compatibility between the motor and the controller cannot be well guaranteed, more and more motor manufacturers provide an integrated motor solution with an integrated controller. With the environmental requirements for energy saving and efficiency improvement of motors and the widespread adoption of energy-saving technologies such as frequency conversion control, more and more power modules are equipped on controllers. [0003] The power ...
