Brushless motor controller capable of self-adapting 110V and 220V voltages

Abstract

The invention discloses a brushless motor controller capable of self-adapting 110V and 220V voltages. The brushless motor controller comprises a microprocessor, a power drive module, a grid voltage detection module, a Hall signal acquisition module and a power supply module. The power supply module is used for supplying power to every circuit, and is composed of a rectification filter circuit, a switch power supply and a voltage stabilizing circuit connected in series. The grid voltage detection module is used for detecting the size of alternating current supply voltage and outputting data to the microprocessor, the Hall signal acquisition module is used for sending the operating data of the brushless motor to the microprocessor, and the microprocessor is used for outputting a control signal to a power drive module to drive the brushless motor to operate. The brushless motor controller adopts a design of electromagnetic compatibility to achieve the effects of anti-interference and isolation.

Description

technical field [0001] The invention relates to the field of brushless motor controllers, and particularly designs a brushless motor controller that can automatically adapt to 110V and 220V voltages. [0002] Background technique [0003] With the continuous development of society, more and more people go abroad and come to our country, but the commonly used mains power standard in the United States, Europe, Japan, etc. is 110V, 60Hz AC voltage, while the commonly used mains power standard in China, Russia and other countries It is 220V, 50Hz AC, the two are not compatible, which brings a lot of inconvenience to the use of electrical appliances, especially the brushless motor controller, so it is necessary to purchase a voltage converter separately during use, which not only increases the cost , and additional power loss is added, which is very uneconomical. [0004] Contents of the invention [0005] In order to solve the above problems, the present invention provides ...
