The invention relates to an alternating-current motor, in particular to an alternating-current motor with an emergency speed reduction device. Firstly, a power supply of a machine body is turned off,a pressing block is pushed rightwards, the pressing block pushes a connecting rod to move rightwards, the connecting rod pushes a transmission rod through a left moving groove, the transmission rod rotates with a center shaft as the center, and a right moving groove of the transmission rod drives a bottom column to move; the bottom column drives a first sliding block and a bottom plate to move. The first sliding block moves leftwards along the first sliding groove. The bottom plate pushes the lower push rod downwards, the lower push rod enables the push plate to move inwards through an inclined face at the bottom, the push plate pushes the push column to move inwards, the push column pushes the fixing base to move inwards, the fixing base pushes the friction plate to move inwards, the friction plate makes contact with the speed reduction plate and rubs with the speed reduction plate, and the speed reduction plate drives the rotating shaft to stop rotating. And the AC motor can be stopped emergently.
Description
technical field [0001] The invention relates to an AC motor, in particular to an AC motor with an emergency deceleration device. Background technique [0002] An AC motor is a machine used to convert mechanical energy and AC electrical energy into each other. Due to the tremendous development of AC power systems, AC motors have become the most commonly used motors. Compared with DC motors, since there is no commutator, the AC motor has a simple structure, is convenient to manufacture, and is relatively strong. It is easy to make a high-speed, high-voltage, high-current, and large-capacity motor. [0003] When the rotating shaft of the AC motor is involved in debris, even if the power is turned off immediately, the rotating shaft will continue to rotate due to inertia and cannot be stopped immediately, and it is difficult to cause certain damage to the internal structure of the AC motor when driving the debris to rotate, making The service life of the AC motor is reduced, r...
