Problems solved by technology
[0003] For some special occasions, ultra-low-speed rotary drive is required, and the rated drive speed of general motors is relatively fast, which cannot meet the demand
If the servo system is used to control the servo motor at low speed, the servo motor will be driven by excessive current during long-term low-speed operation, which will greatly reduce the service life of the servo motor
If an additional reducer is used, the overall volume of the motor and reducer is large, making it difficult to apply in a small space

The invention provides a novel low-speed motor. The motor comprises a housing, a seal cover, a gear ring, a flexible gear cup, an output shaft, a control box and an excitation winding, wherein the housing is hat-shaped and a shaft hole is formed in the center of the end surface of the housing; inner teeth are arranged on the inner side of the gear ring in a circumferential direction and the gear ring is made from a rigid material and rigidly fixed to the inner wall of the housing; the flexible gear cup is arranged in the gear ring, and outer teeth are arranged on the outer edge of the flexible gear cup and are not engaged with the inner teeth of the gear ring under the condition that the flexible gear cup does not deform; each outer tooth of the flexible gear cup is correspondingly embedded with a magnetizer; the excitation winding is provided with excitation coils arranged along the circumference and is arranged outside the gear ring; the seal cover is packaged on the housing and a shaft hole is formed in the center of the seal cover; the output shaft is connected with the flexible gear cup and penetrates out of the shaft hole of the housing from the shaft hole of the seal cover in an axial direction; and the control box is arranged outside the housing and electrically connected with the excitation winding. According to the motor, low-speed rotary driving can be performed.
Description
technical field [0001] The invention relates to the field of precision transmission devices, in particular to a novel low-speed motor. Background technique [0002] The motor is an important driving component in the mechanical field, and there are various designs to meet different driving requirements. [0003] For some special occasions, ultra-low-speed rotary drive is required, and the rated drive speed of general motors is relatively fast, which cannot meet the demand. If the servo system is used to control the servo motor at low speed, the servo motor will be driven by excessive current during long-term low-speed operation, which will greatly reduce the service life of the servo motor. If an additional reducer is used, the overall volume of the motor and reducer is large, making it difficult to apply in a small space. [0004] It is not difficult to see that there are certain defects in the prior art. Contents of the invention [0005] The technical problem to be so...
