Abstract
The utility model discloses a high-power direct-current brushless motor control circuit for a flat car. The circuit comprises a diode rectifier bridge which is connected with an external power supply, and a controller connected with the diode rectifier bridge. A transformer is arranged between the external power supply and the diode rectifier bridge. The transformer is a step up transformer. The external power supply is an alternating-current power supply. According to the high-power direct-current brushless motor control circuit, a step up transformer is added to the power supply part of the original controller, such that a low voltage input from the external power supply passes through the step up transformer, and the current bore by the controller is reduced, thereby reducing the production cost of the controller.
Description
Technical field
The utility model relates to the improvement of DC brushless motor controller, particularly a kind of high power DC brushless electric machine control circuit for flat car.
Background technology
