A switched reluctance motor controller mainboard radiator for a novel angle grinder and the angle grinder

Abstract

The invention provides a switched reluctance motor controller mainboard radiator for a novel angle grinder. A heat dissipation body is provided with a mainboard placement groove. Heat dissipation mechanism placement grooves are arranged in the two sides of the mainboard placement groove. Common groove walls are arranged between the mainboard placement groove and the heat dissipation mechanism placement grooves. Mainboard placement holes are arranged in the common groove walls. A switched reluctance motor controller mainboard is placed in the mainboard placement groove, and is fixedly arrangedin the mainboard placement groove through the mainboard placement holes. A mainboard placement groove bottom radiating fin is arranged on the bottom of the mainboard placement groove. Two bosses are also arranged on the bottom of the mainboard placement groove. The bosses are arranged on the mainboard placement groove bottom radiating fin so as to make space distance be arranged between the switched reluctance motor controller mainboard and the mainboard placement groove bottom radiating fin which are placed in the mainboard placement groove. The mainboard radiator adopts integrated design, the length of the radiating fin is customized according to a shell, and so the maximum internal area of an angle grinder controller is kept and the heat dissipation capability of the controller board isenhanced.

Description

technical field [0001] The invention relates to the technical field of angle grinders, in particular to a novel angle grinder-used switch reluctance motor controller motherboard radiator and an angle grinder. Background technique [0002] The angle grinder uses high-speed rotating sheet grinding wheels, rubber grinding wheels, wire wheels, etc. to grind, cut, derust, and polish metal components. [0003] At present, the angle grinder has used the switched reluctance motor as the drive system, and the switched reluctance drive system (Switched Reluctance Drive referred to as SRD) is a new type of AC drive system developed rapidly in the mid-1980s. It also has DC drive And the advantages of AC drive; From the perspective of composition, it consists of two parts: a switched reluctance motor (SRM) and a driver. Among them, the switched reluctance motor is composed of an SRM body and a position detector (such as a photoelectric sensor) on the body; the driver is composed of a ...

Problems solved by technology

At the same time, when the angle grinder is working, the electronic components on the main control board of the controller will generate heat energy. If the temperature is too high, the power electronic devices will be lost, and even the circuit board will be burned in severe cases.
