Description

Technical Field

[0001] The utility model relates to the technical field of permanent magnet motors, in particular to a permanent magnet electric roller. Background Art

[0002] Permanent magnet electric drums are a type of permanent magnet motor. They also have an external rotor structure with the stator inside the drum. They feature high magnetic field strength, a large depth, a simple structure, ease of use, no maintenance, low power consumption, and resistance to demagnetization even after years of use. Compared to asynchronous motors of the same size and specification, permanent magnet electric drums offer greater torque. This high torque requires greater braking or backstop torque, which results in larger brakes and backstops, requiring greater space. When existing permanent magnet electric drums require the addition of brakes and backstops to accommodate site conditions, limited space and compact structures often leave insufficient space and space for mounting these devices.
