AI Technical Summary

Technical Problem

The controllers of existing circular saws have poor heat dissipation effects, resulting in excessive temperature rise, which in turn reduces the service life of circular saws.

Method used

The controller is split into a control component and a power component. The control component is small in size and can be placed in any position, while the power component is set at the air inlet position of the motor cavity to dissipate heat by circulating air.

Benefits of technology

Through the improved heat dissipation design, the service life of the controller is improved, and the space occupied by the overall circular saw is reduced, which improves the installation effect.

Abstract

The utility model particularly relates to a controller and an electric circular saw, the controller is installed inside the electric circular saw, and the controller specifically comprises a control assembly and a power assembly. The power assembly is used for being installed in a motor cavity of the shell and is arranged close to an air inlet of the motor cavity. The power assembly is used for being installed inside the shell, the control assembly is used for outputting corresponding control signals of a motor of the electric circular saw and receiving and processing various signals returned by the motor, and the control assembly is electrically connected with the power assembly. According to the controller, the controller is divided into the control assembly and the power assembly, the control assembly is small in size, can be placed at any position and does not need heat dissipation, and the power assembly can be arranged at the air inlet of the motor cavity so that heat dissipation processing of the controller can be achieved, and therefore the service life of the controller can be prolonged. Meanwhile, the controller structure is small in occupied space, and the installation effect of the controller structure can be improved.
