Abstract

A motor journal sticking mechanism comprises a journal sticking body, a movable disc, a wave-shaped spring piece, an electromagnet and a base, wherein the journal sticking body is conical, a middle hole is used for allowing a motor shaft to penetrate through, and a plurality of grooves are cut in the circumferential direction of the journal sticking body; and when the electromagnet is powered off, the wave-shaped spring piece pushes the movable disc to act on one end of the journal sticking body, so that the journal sticking body shrinks in the radial direction, and the motor shaft penetrating through the middle hole is tightly held. According to the motor journal sticking mechanism, the motor shaft can be locked after a motor is powered off, accidental rotation is prevented, the motor shaft is held tightly after the motor is powered off, and the state is completely consistent with the state of the motor shaft before the motor is powered off.

Description

technical field [0001] The invention relates to a motor, in particular to a motor shaft holding mechanism. Background technique [0002] The rotating motor is the most commonly used driving component. Locking the motor shaft after the motor movement ends can prevent the motor shaft from rotating unexpectedly. In addition, for special driving motors such as stepping motors, it can also prevent the motor from being damaged due to the structural reasons of the motor when the power is turned off during non-full-step motion. The resulting callback movement. The general motor shaft holding mechanism has a certain gap, which cannot guarantee that the motor shaft will not move completely after the power is turned off. Contents of the invention [0003] The purpose of the present invention is to provide a motor shaft holding mechanism, which can lock the motor shaft after the motor is powered off, prevent accidental rotation, and hold the motor shaft completely still after the pow...
