The invention provides a vector braking system and method for an electric roller, the system comprises a driver and the electric roller, and the driver comprises a braking force regulator; the driver is used for receiving a braking instruction and acquiring the rotating speed of the electric roller; when the rotating speed of the electric roller is greater than a first preset rotating speed, the driver sends a braking instruction to the braking force regulator; the braking force regulator is used for providing a vector opposite to the current rotating direction of the electric roller for the electric roller based on a braking instruction for braking until the rotating speed of the electric roller is smaller than or equal to a second preset rotating speed; and when the rotating speed of the electric roller is smaller than or equal to a second preset rotating speed, the braking force regulator sends a lower pipe full-conduction instruction to the electric roller until braking of the electric roller is finished. According to the invention, negative vector is adopted during motor braking, and meanwhile, a braking force regulator is added, so that the motor and a driving board card are prevented from being damaged due to overlarge braking current.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a vector braking system and method for an electric roller. Background technique [0002] At present, the drive methods of permanent magnet synchronous motors are mainly divided into two categories, one is square wave drive, and the other is sine wave drive. Both have their own advantages and disadvantages, and the choices are different depending on the application object. [0003] The direct drive electric roller has great advantages in terms of cost and manufacture because there is no reduction gear in application. Generally speaking, the direct-drive electric roller is divided into inner rotor and outer rotor according to the structure of the motor. This invention mainly introduces the use of the inner rotor. Usually, the inner rotor motor drives several unpowered rollers through a wedge-shaped drive pulley and a multi-ribbed belt. . Due to the lack of a reduction gear struct...
