Problems solved by technology
This deceleration method needs to rely on accurate and reliable electrical components, which undoubtedly increases the manufacturing cost of mechanical products. Under the condition of low cost and low requirements, it is suspected of wasting resources; and the maintenance and maintenance requirements of electrical components are relatively high. , in the case of a relatively harsh environment, the frequency of maintenance and maintenance is high, resulting in high maintenance costs

The invention proposes an automatic speed-limiting motor equipped with three speed-limiting plates and a turntable, the three speed-limiting plates are fixedly connected to the housing of the motor body, and evenly distributed on the outer periphery of the turntable; the turntable can rotate synchronously with the rotating shaft of the motor body , there are three slideways evenly arranged on the turntable, each slideway is provided with a slide bar, the outer end of the slide bar is provided with a friction plate, and a spring is set on the slide bar; The greater the centrifugal force received, when the centrifugal force is greater than the elastic force of the spring, the sliding rod and the friction disc move along the slideway away from the rotating shaft, and then contact the speed limiting plate, the friction between the speed limiting plate and the friction disc reduces the motor speed, And then play the role of automatic speed limit. On this basis, the present invention also proposes a crane with the automatic speed-limiting motor.
Description
technical field [0001] The invention relates to motor speed control technology, in particular to an automatic speed-limiting motor; in addition, it also relates to a crane using the automatic speed-limiting motor. Background technique [0002] An electric motor is a rotary electric machine that converts electrical energy into mechanical energy. It mainly includes an electromagnet winding or distributed stator winding for generating a magnetic field and a rotating armature or rotor. Under the action of the rotating magnetic field of the stator winding, a current passes through the armature squirrel-cage aluminum frame and is subjected to the action of the magnetic field to make it rotate. [0003] At present, electric motors have been widely used as prime movers in various mechanical products, such as rice milling machines, lifting mechanisms of gantry cranes, machine tools, water pumps, belt conveyors, fans, etc.; Changes in the situation, and sometimes even the situation o...
