Description

Large-torque automobile door handle actuator motor capable of being installed rapidly Technical Field The utility model relates to the technical field of motors, in particular to a motor of a large-torque automobile door handle actuator capable of being quickly installed. Background The automobile door handle actuator generally requires quick response, short action time and convenient installation, and in order to meet the requirements, not only the sensor and the control circuit are required to meet the control requirements, but also the performance of the direct current motor as an actuating component is particularly important, namely, the motor is required to have small cogging torque and large starting torque, but in general, the automobile door handle actuator has smaller motor size, so that the power density of the motor is required to be improved as much as possible, the starting torque of the motor is improved and kept small cogging torque under the limited size, and the motor is difficult to design and install conveniently. In order to meet the requirement of starting moment, the existing general scheme is to adopt a high-performance neodymium iron boron magnet to improve the power density of the motor, the casing is designed to be round, two mounting threaded holes are designed, but the screw is required to be fastened when the design scheme is mounted, the quick mounting requirement is not met, and the cogging moment of the motor is difficult to optimize to an allowable range. Therefore, there is a need to design a high torque automotive door handle actuator motor that can be quickly installed to address one or more of the deficiencies of the prior art. Disclosure of Invention The technical scheme is that the motor of the large-torque automobile door handle actuator capable of being quickly installed is characterized by comprising a square motor shell, wherein a rotor is rotatably arranged in the motor shell, one end of the motor shell is clamped with an end cover, neodymium iron boron magnets are respectively arranged at four corners of the inner side of the motor shell, iron cores of the rotor are in a six-groove shape, and two carbon brushes are arranged in the end cover at intervals of 90 degrees. In a preferred embodiment, a mounting ring is further disposed on the inner side of the motor housing, and four neodymium-iron-boron magnets are fixedly disposed on the outer side of the mounting ring at intervals of 90 °. In a preferred embodiment, two auxiliary grooves are respectively formed on the surface of each iron core tooth pole of the rotor. The utility model has the beneficial effects that the square motor shell is used for realizing quick installation and positioning, screw fastening is not needed, the space of the motor shell is utilized to the maximum degree through the matching of six grooves and quadrupoles, the cogging moment is reduced, and meanwhile, the cogging moment is further reduced through the design of the auxiliary groove, so that the large moment and the small cogging moment are realized, and the use requirement is met.
