Description

Technical Field

[0001] This utility model belongs to the technical field of AC / DC brushless motors, specifically relating to an AC / DC brushless motor. Background Technology

[0002] A brushless DC motor consists of a motor body and a driver, and is a typical mechatronic product. A brushless motor refers to a motor without brushes and a commutator (or slip rings), also known as a commutatorless motor. While brushless DC motors share the same working principle and application characteristics as conventional DC motors, their composition differs. In addition to the motor itself, the former includes a commutation circuit, and the motor and commutation circuit are tightly integrated. Existing brushless DC motors cannot achieve AC / DC compatibility; therefore, this invention proposes an AC / DC brushless motor. Utility Model Content

[0003] The purpose of this invention is to provide an AC / DC brushless motor to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an AC / DC brushless motor, including a motor base, a motor shaft rotatably mounted at the center of the motor base via a bearing sleeve, a rotor mounting sleeve fixedly mounted on the outer side of the motor shaft, a rotor fixedly mounted on the inner side of the rotor mounting sleeve, a stator mounted on the inner side of the rotor, the stator being sleeved on the outer side of the motor shaft and fixedly mounted to the motor base, a drive control board being provided inside the motor base, the drive control board being provided with an MCU microcontroller, a motor power amplifier module, a power supply, a power converter, and a motor control terminal, and the MCU microcontroller, the motor power amplifier module, the power supply, the power converter, and the motor control terminal being electrically connected to each other.

[0005] Preferably, the edge of the motor base is provided with an extended skirt, and the extended skirt is provided with a fixing through hole for installation.

[0006] Preferably, a ring of arc-shaped magnetic blocks is uniformly arranged on the inner side of the rotor, and multiple T-shaped winding groups are distributed on the outer circumference of the stator.

[0007] Preferably, the power supply can convert AC power into DC power to power the power amplifier module and MCU microcontroller, as well as power the motor control terminal, through a power converter.

[0008] Preferably, when DC power is supplied, the DC power output terminal of the motor control terminal can also be used as the DC power input terminal, which is converted by the power converter to supply power to the MCU microcontroller and the motor power amplifier module.

[0009] Compared with the prior art, the beneficial effects of this utility model are: the entire drive control board of the motor integrates a power converter, which converts AC power into DC power to power the motor power amplifier module and MCU microcontroller, and also outputs another power supply to the motor control terminal.

[0010] Furthermore, the DC power output terminal can also be used as a DC power input terminal. When DC power is supplied, this port serves as a DC power input terminal, which is converted by the power converter to supply power to the MCU microcontroller and motor power amplifier module. This achieves both AC-DC conversion and DC-DC conversion at a relatively low cost. Attached Figure Description
