AC voltage frequency of stator winding of gear reducer

AC voltage frequency of stator winding of gear reducer

2024-04-23

For example, a gear reducer stator winding AC voltage frequency f = 50Hz, the stator winding magnetic logarithm p = 3, then the rotating magnetic field speed n = 60 × 50 ÷ 3 = 1000r/min. When the motor is running, the direction of the rotor is the same as the direction of the rotating magnetic field. The rotor is rotated by the rotating magnetic field. The speed of the rotor is less than the speed of the rotating magnetic field and lags behind the speed of the rotating magnetic field. The speed of the rotating magnetic field is not synchronized. Such a motor whose rotor speed is not synchronized with the rotating magnetic field speed is called an asynchronous motor.

In the field of low-noise motors, we have contributed to this. The gear reduction motor is a power transmission mechanism that uses a gear speed converter to decelerate the number of revolutions of the motor (motor) to the desired number of revolutions, and Get a larger torque mechanism. In the current mechanism used to transmit power and motion, the application range of the gear motor is quite wide. Low noise type deceleration motor should be the subject of research and development of our deceleration machine enterprises. The noise of the gear reduction motor has a great influence on the working stability accuracy, the contact accuracy of the gear, the movement accuracy of the gear, the assembly accuracy and so on. In order to reduce the noise of the gear reduction motor, it is necessary to know the cause of the noise. The noise of the gear is caused by the vibration caused by the periodic alternating force generated by the meshing of the gears in the machine during its operation.

Reducer can not run overload

Reducer can not run overload

The reducer manufacturer said that this situation is just like the lighting lamp in the home. The current is very large when starting, but the current will be larger during normal use than when starting, and so will the motor. What is the principle for this? Here we need to understand from the perspective of motor starting principle and motor rotation principle: when the induction motor is in a stopped state, from an electromagnetic point of view, it is like a transformer. The stator winding connected to the power supply is equivalent to the primary coil of the transformer, and the closed-circuit rotor winding is equivalent to the secondary coil of the transformer that is short-circuited. There is no electric connection between stator winding and rotor winding, only magnetic connection, magnetic flux through the stator, air gap, rotor core into a closed circuit. At the moment of closing, the rotor has not yet rotated due to inertia, and the rotating magnetic field cuts the rotor winding at a larger cutting speed-synchronous speed, so that the rotor winding induces a higher potential that may be reached. Therefore, a large current flows in the rotor conductor. This current generates magnetic energy that offsets the stator magnetic field, just as the secondary magnetic flux of the transformer offsets the primary magnetic flux.

The speed ratio of planetary reducer has different efficiencies. Output torque = input power * 9549/input speed * transmission ratio * efficiency. Helical gears can be regarded as cylindrical gears arranged by a group of thin-plate gears with appropriate teeth. In this way, the contact of each piece is at different parts of the tooth profile, thus producing the effect of compensating the error of each thin-plate gear. This compensation effect is very effective due to the elasticity of the gear teeth, thus obtaining such a result, A tooth with an error within 10mm can average the error, so that it can run smoothly under load as a tooth with an error within 1mm. Because at any instant in time, about half of the time (assuming an overlap of about 1.5) there will be two teeth meshing, this brings an additional benefit in terms of strength. Thus the stress may be based on 1.5 times the tooth width rather than one tooth width.

As an essential component of screw lift and other transmission products, the stability of the hard tooth surface reducer plays an important role in the whole transmission system. However, if the hardness of the hard tooth surface reducer fails to meet the requirements during the purchase process, or the use cycle is too long, or the overload is too long, it will accelerate the wear of the hard tooth surface gear, which will affect the normal operation of the transmission system.
